| FG000 | Cohort A | Cohort A included pediatric participants (full-term newborns to <18 years) in which a CVC was recently placed and who were asymptomatic for CVC-related deep vein thrombosis (DVT). Imaging procedures occurred on Day 40 ± 20 days relative to catheter placement (Day 0) and included: ultrasound (US) and magnetic resonance imaging (MRI), with and without contrast enhancement. The MRI and US were to be done within 48 hours of each other. An approved gadolinium contrast agent at a dose which was considered 'state-of-the-art' or standard institutional practice at the specific site and in accordance with the country-specific regulatory guidance was to be used for MRI with contrast. No sedation or anesthesia was to be allowed. Participants who developed symptoms of VTE prior to imaging should have been switched to Cohort B. |

| Number of Participants and Reasons for Non-Completion of Each of the Imaging Procedures, Ultrasound (US), MRI With Contrast and MRI Without Contrast | Bilateral US was attempted but if it could not be completed, a unilateral US was accepted for analysis. Participants who did not complete the MRI procedure with contrast could be different participants from those who did not complete the MRI procedure without contrast. Primary reasons for non-completion of imaging included: technical, investigator decision, child refused, parent refused, child missed appointment, difficulties with anesthesia/sedation, child unable to lie still, problems with contrast administration, and other reasons. Other reasons could include: late to appointment and unable to perform MRI due to time constraints; logistical reasons, parent agreed to only ultrasound at time of consent, schedule delay, equipment not available, difficulty putting patient in correct position. Due to the small numbers of participants in some cohorts, these data were more meaningful with all cohorts grouped together for the total imaged population. | Either Day 40±20 days following the placement of CVC (cohort A) or within 7 days of: symptoms of DVT or incidental diagnosis of CVC-related DVT(cohort B) or Day of MRI + 48 hours (cohort C). |
| Number of Participants With an Adjudicated Deep Vein Thrombosis (DVT) Detected By a Study-Related Ultrasound (US) and/or MRI, By Cohort and Age Group | MRI with contrast (c) and without (w/o) contrast (c) enhancement were performed and a US was done within 48 hours of the MRI. Once detected, the DVT was adjudicated and confirmed by an independent central adjudication Committee (ICAC) consisting of experienced physicians not involved in the study and blinded to each participant's identity and clinical course. Participants were considered positive for DVT if at least one of the radiographic procedures was positive. Cohort A: Day 0=day of catheter placement; Day 40 (± 20 days)=day of imaging procedures at Visit 1, or if possible within 72 hours after a CVC is removed or lost. Cohort B Visit 1: within 7 days of initiation of symptoms of a CVC-related DVT (symptoms include but were not limited to: redness, pain/tenderness, swelling, presence of subcutaneous collaterals, catheter occlusion, and the presence of catheter related infection) or within 7 days of an incidental diagnosis of CVC-related DVT by radiographic imaging. | Either Day 40±20 days following the placement of CVC (cohort A) or within 7 days of: symptoms of DVT or incidental diagnosis of CVC-related DVT(cohort B) or Day of MRI + 48 hours (cohort C) |
| All Participants With an Adjudicated Deep Vein Thromboembolism (DVT) By Study-Related Radiographic Procedures That Diagnosed the DVT | Adjudication was by an Independent Central Adjudication Committee (ICAC) consisting of experienced physicians not involved in the study and blinded to each participant's identity and clinical course. One set of 3 study-related diagnostic imaging procedures (US, MRI with contrast, and MRI without contrast) was performed. Participants were considered positive for DVT if at least one of the radiographic procedures was positive. | Either Day 40±20 days following the placement of CVC (cohort A) or within 7 days of: symptoms of DVT or incidental diagnosis of CVC-related DVT(cohort B) or Day of MRI + 48 hours (cohort C) |
| Either Day 40±20 days following the placement of CVC (cohort A) or within 7 days of: symptoms of DVT or incidental diagnosis of CVC-related DVT(cohort B) or Day of MRI + 48 hours (cohort C) |
| Number of Participants With Adjudicated Pulmonary Embolism (PE) Events (Symptomatic or Asymptomatic) Identified During the Study | Signs and symptoms of PE include shortness of breath, pleuritic pain, cough, orthopnea, wheezing, and may have associated signs and symptoms of DVT. In the event a PE was detected while undergoing the study MRI or other imaging procedure required for care of an underlying condition, and the participant did not manifest any signs and/or symptoms of a PE, the event was considered an asymptomatic PE. The participant was managed and further investigated according to the investigator's standard of care. All diagnostic imaging procedures performed, such as contrast-enhanced computer tomography (CT) pulmonary angiogram, nuclear ventilation perfusion lung scan (V/Q scan), were submitted for adjudication as a suspected PE. | Enrollment up to Visit 1 plus 30 days (up to approximately 90 days) |
| Number of Deaths Which Occurred During the Study | Death as an endpoint in a participant with an adjudicated venous thromboembolism (DVT or PE) was summarized, regardless of the cause of the death. The VTE was adjudicated by a blinded central independent adjudication committee. | Enrollment up to last US or MRI plus 30 days (up to approximately 90 days) |

| FG001 | Cohort B | Cohort B included pediatric participants (full-term newborns to <18 years) with a CVC and who were either symptomatic for a CVC-related DVT or had an incidental diagnosis of CVC-related DVT based on radiographic imaging performed for other clinical reasons. Diagnostic imaging procedures, US and MRI (with and without gadolinium contrast enhancement) were to be done within 48 hours of each other or, for those with therapeutic anticoagulation, within 24 hours. Aesthesia/sedation allowed as routine standard of care for participants only if symptomatic for a CVC-related DVT. For those participants symptomatic for a CVC-related DVT, MRI and US were to be initiated within 7 days of symptoms. In those participants with an incidental diagnosis of a CVC-related DVT made by radiographic imaging performed for clinical reasons, MRI and US were to be done within 7 days of the diagnosis of the CVC-related DVT. |
| FG002 | Sub-Study Cohort C | A Sub-study with additional cohort C was initiated to collect diagnostic imaging procedures for the detection of CVC-related DVT in a population < 18 years of age who had a CVC in place and who were scheduled to undergo a contrast enhanced MRI in any part of their body as part of their clinical care and who allowed the diagnostic imaging procedure to include the area around the CVC. Participants who developed symptoms of VTE prior to imaging should have been switched to Cohort B. |

| OG006 | Cohort C Newborn to <2Years | Pediatric participants with a CVC in place and having an MRI for clinical reasons were enrolled were enrolled in the substudy, Cohort C. An ultrasound was to be performed around the area of the CVC within 48 hours of the MRI. The MRI was performed both with and without contrast. |
| OG007 | Cohort C 2Years to <12Years | Pediatric participants with a CVC in place and having an MRI for clinical reasons were enrolled in the substudy, Cohort C. An ultrasound was to be performed around the area of the CVC within 48 hours of the MRI. The MRI was performed both with and without contrast. |
