Multiple sclerosis patients who are stable on interferon therapy show better outcomes when staying on same therapy than patients who switch to another interferon.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundReal-world outcomes from staying on an interferon beta (IFNβ) vs switching to another IFNβ could help guide treatment decisions. This study's objective was to compare outcomes of stable multiple sclerosis (MS) patients on an IFNβ who stayed on therapy vs those who switched to another IFNβ.
methodsMS patients were identified from the Optum Insights Clinformatics Data Mart Multi-Plan who were 18-64 years old and relapse-free (stable) over 1 year while continuously being treated with an IFNβ. Patients were propensity score matched 3:1 using age, gender, initial IFNβ, adherence, and month and year for patients who stayed on the initial IFNβ (No Switch) to patients who switched to another IFNβ (Switch). Patients had to be continuously enrolled for 1 year prior to and 1 year after the index date (date of the first claim of the switched-to IFNβ or the match date when continuing on initial IFNβ treatment). Patients were enrolled with index dates between January 1, 2005 and September 30, 2014. Relapses were recorded during the 1-year follow-up period after index date.
resultsAfter matching, there were 381 patients in the Switch group and 1,143 in the No Switch group. Baseline characteristics were well matched between groups (average age 46 years, 72% female). The percentage of patients experiencing a relapse during the follow-up was significantly higher in the Switch group than in the No Switch group (21% vs 12%,
conclusionMS patients stable on IFNβ therapy who remain on initial therapy had significantly better outcomes (lower annual relapse rate and percentage of patients with relapses) than patients who switched to another IFNβ. This supports the benefits of allowing patients to remain on current IFNβ therapy when stable.
