Abstract

Objective: To investigate the impact of interferon‐beta (IFNβ) on disease progression in relapsing‐remitting multiple sclerosis patients. Methods: A cohort of 1,504 relapsing‐remitting multiple sclerosis (1,103 IFNβ–treated and 401 untreated) patients was followed for up to 7 years. Cox proportional hazards regression adjusted for propensity score inverse weighting was used to assess the differences between the two groups for three different clinical end points: secondary progression (SP) and irreversible Expanded Disability Status Scale (EDSS) scores 4 and 6. Times from first visit and from date of birth were used as survival time variables. Results: The IFNβ–treated group showed a highly significant reduction in the incidence of SP (hazard ratio [HR], 0.38, 95% confidence interval [CI], 0.24–0.58 for time from 1st visit; HR, 0.36, 95% CI, 0.23–0.56 for time from date of birth; p < 0.0001), EDSS score of 4 (HR, 0.70, 95% CI, 0.53–0.94 for time from first visit; HR, 0.69, 95% CI, 0.52–0.93 for time from date of birth; p < 0.02), and EDSS score of 6 (HR, 0.60, 95% CI, 0.38–0.95 for time from first visit; HR, 0.54, 95% CI, 0.34–0.86 for time from date of birth; p ≤ 0.03) when compared with untreated patients. SP and EDSS scores of 4 and 6 were reached with significant delays estimated by times from first visit (3.8, 1.7, and 2.2 years) and from date of birth (8.7, 4.6, and 11.7 years) in favor of treated patients. Sensitivity analysis confirmed findings. Interpretation: IFN‐β slows progression in relapsing‐remitting multiple sclerosis patients. Ann Neurol 2007;61:300–306

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
