The Visual Analog Scale (VAS) is an instrument used to measure a person's subjective quantitative evaluation of an item such as pain intensity. The VAS contains a continuous line between two end points whereby the respondent places a mark on the line to indicate his or her response. In this study, patients scored their pain intensity in the most affected joint of the gout flare on a 0 100 mm VAS. The scale ranged from 0 (no pain) to 100 (unbearable pain). The scores were measured to the nearest millimeter from the left. Missing pain intensity data at 72 hours was imputed using the Last-Observation-Carried-Forward (LOCF) method.

Full Analysis Set: The Full Analysis Set (FAS) consisted of all patients as randomized that had at least one dose of study drug. Following the intent-to-treat principle, patients were analyzed according to the treatment they were assigned to at randomization.

A Likert scale is a type of scale with a range of responses corresponding to an item such as pain. The respondent selects the best response that indicates the respondent's subjective evaluation of the item. Patients scored their pain intensity in the most affected joint of the gout flare on a 5-point Likert scale (none, mild, moderate, severe, extreme). The scores were measured to the nearest millimeter from the left. The LOCF method was used to impute post-dose pain intensity Likert measurements up to 14 days.

Patients met the definition of a new flare if they had: a flare in a joint, which was not a previously affected joint (at baseline or during the study), or a flare in a joint previously affected (at baseline or during the study) after the previous flare in that joint had resolved completely according to the patient's perception. Patients did NOT meet the criterion of having a new gout flare if they had increasing/renewed gout pain in an affected joint before the flare had resolved completely.

Patients did NOT meet the criterion of having a new gout flare if they had increasing/renewed gout pain in an affected joint before the flare had resolved completely. Less than 50% of patients had new flares. Therefore, the median time to new flare could not be calculated.

Patients completed diary entries at 6, 12, 24, 48 and 72 hours post dose and then daily up to 7 days post-dose and/or daily until resolution of the flare. Kaplan Meier estimate of time to resolution of gouty flare as reported by patient, along with associated 95% confiedence interval, were reported.

A Likert scale is a type of scale with a range of responses corresponding to an item such as pain. The respondent selects the best response that indicates the respondent's subjective evaluation of the item. Patients scored their response to treatment on a 5-point Likert scale (excellent, good, acceptable, slight, poor). This outcome measure shows the number of patients indicating each score on the scale.

The study physician assessed the most affected joint for tenderness. Tenderness was measured on a 0 - 3 point scale as follows: 0 = no pain, 1 = patient states that "there is pain", 2 = patient states "there is pain and winces" and 3 = patient states "there is pain, winces and withdraws" on palpation or passive movement of the affected study joint.
