Long-term efficacy and safety of three times weekly dosing regimen of glatiramer acetate in relapsing multiple sclerosis patients: Seven-year results of the Glatiramer Acetate Low-frequency Administration (GALA) open-label extension study.

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
objectiveDescribe the long-term outcomes of early-start (ES) and delayed-start (DS) glatiramer acetate 40 mg/mL treatment three times weekly (GA40) for up to seven years in the Glatiramer Acetate Low-frequency Administration (GALA) study in patients with relapsing multiple sclerosis (RMS).
methodsPatients were evaluated every three to six months. The primary efficacy endpoint was annualized relapse rate (ARR); additional endpoints were exploratory or post hoc. For efficacy, data from the entire exposure period were used for the ES and DS cohorts. For safety, exposure only under GA40 was considered.
resultsOf the patients who continued into the open-label extension (OLE), 580/834 (70%) ES and 261/419 (62%) DS completed the OLE. For the entire placebo-controlled and OLE study period, ARR was 0.26 for ES and 0.31 for DS patients (risk ratio = 0.83; 95% confidence interval [CI]: 0.70-0.99). ES prolonged median time to first relapse versus DS (4.9 versus 4.3 years; hazard ratio = 0.82; 95% CI: 0.6-0.96). OLE-only results showed DS patients experienced similar efficacy for relapse and disability outcomes as ES patients. Adverse events were consistent with the well-established GA safety profile.
conclusionsGA40 treatment conferred clinical benefit up to seven years, resulting in sustained efficacy and was generally well tolerated in RMS patients.
