RESYZE was a non-interventional/observational, retrospective, multi-center study conducted in 28 public and private hospitals in Spain, assessing secondary progressive multiple sclerosis (SPMS) patients in a real-world setting. Patients underwent clinical assessments and received their standard routine medical care, as determined by their treating physicians. The study used secondary data i.e., electronic medical records (EMR) from hospitals. Patients who met the eligibility criteria were selected from the EMR of each of the sites, to include adult SPMS diagnosed patients who received at least one dose of siponimod during the start of treatment period between April 2021 and 01 September 2022, with a 12-month observation period, regardless of whether or not they continued the treatment. The study compiled data that was available in the hospital EMR from each patient up to 24 months before the first siponimod dose, and 12 months after the first siponimod dose. Data were collected for each patient at regular intervals of 6/12 months and within a window period of ±45 days, as available.

| Number of Patients by Number of Relapses in the 12 Months Before Starting Siponimod Treatment | Baseline |
| Number of Patients by Number of Relapses in the 24 Months Before Starting Siponimod Treatment | Baseline |
| Number of Patients by Number of Gadolinium T1 (Gd-T1) Lesions 24 Months Before Starting Siponimod Treatment | Baseline |
| Baseline Expanded Disability Status Scale (EDSS) Score at the Start of Siponimod Treatment | The EDSS uses an ordinal scale to assess neurologic impairment in MS based on a neurological examination. Scores in each of 7 functional systems (Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, and Cerebral) and an ambulation score were combined to determine the EDSS score. The scale ranges from 0 to 10, with 0 being normal neurological exam and 10 being death due to MS. | Baseline |
| Number of Patients With Cognitive Decline Diagnosis | Baseline |
| EDSS Cognitive Subscale Score in Patients With Cognitive Decline | The EDSS cognitive subscale is used to grade the decrease in mentation inside the Cerebral Functional System of the EDSS scale. The scale ranges from 0 to 5, with 0 being normal (no decrease in mentation) and 5 being dementia, confusion and/or complete disorientation. | Baseline |
| Number of Patients by Comorbidity | Baseline |
| Up to 12 months |
| Number of Patients by Reason for Temporal Discontinuation of Siponimod Treatment | Up to 12 months |
| Number of Patients by Reason for Permanent Discontinuation of Siponimod Treatment | Up to 12 months |
| Number of Patients Who Started a New Disease Modifying Treatment After Permanent Discontinuation of Siponimod Treatment | Up to 12 months |
| Number of Patients by New Disease Modifying Treatment After Permanent Discontinuation of Siponimod Treatment | Up to 12 months |

| Number of Patients by Type of Concomitant Treatment Received for Symptomatic Treatment of MS | Up to 12 months |

| Number of Patients who Needed a Siponimod Dose Modification | Up to 12 months |
| Number of Patients by Reason for Siponimod Dose Modification | Up to 12 months |
| Number of Patients who Needed First Dose Observation | Day 1 of the 12-month observation period |
| Number of Patients who Reported an Adverse Event During First Dose Observation | Day 1 of the 12-month observation period |
| Number of Patients who Reported an Adverse Event During Treatment With Siponimod | Up to 12 months |

| Number of Patients With Adverse Events Which Led to Temporary Discontinuation or Dose Adjustment of Siponimod Treatment | Up to 12 months |
| Number of Patients With Serious Adverse Events Which Led to Permanent Discontinuation of Siponimod Treatment | Up to 12 months |
| Number of Patients With Serious Adverse Events Which Led to Temporary Discontinuation or Dose Adjustment of Siponimod Treatment | Up to 12 months |
| Number of Patients Who Died During Treatment With Siponimod | Up to 12 Months |
| Number of Patients by Lymphopenia Grade During Treatment With Siponimod | Lymphopenia grades:
| Baseline, Month 6, Month 12 |
| Number of Patients With Confirmed Disability Progression During Treatment With Siponimod | Confirmed Disability Progression was determined by an increase of at least 1 point in the Expanded Disability Status (EDSS) score if the baseline EDSS was 5.5 or less, or an increase of 0.5 points in the EDSS score if the baseline EDSS score was greater than 5.5 confirmed in a second visit performed at least 3 months apart. The EDSS uses an ordinal scale to assess neurologic impairment in MS based on a neurological examination. Scores in each of 7 functional systems (Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, and Cerebral) and an ambulation score were combined to determine the EDSS scores, ranging from 0 (normal) to 10 (death due to MS). | Up to 12 months |
