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
We compared the efficacy and safety of a biosimilar form of beta-interferon-1a (Actovex) versus the reference product in the treatment of relapsing remitting multiple sclerosis (RRMS). In a double blind, randomized phase 3 clinical trial, we evaluated 138 patients with RRMS that were allocated to receive the biosimilar medication and the reference treatment (30 μg intramuscular, weekly for one year). We investigated changes in EDSS, relapse rate and MRI changes within one year. In sixty-nine patients who were allocated to each arm and analyzed mean age and its standard deviation was 32.4 ± 8.8 and 31.5 ± 8 for the biosimilar medication and the reference arm respectively. One-year follow-up revealed a mean difference of 0.084 in EDSS (95% CI: 0.069-0.237) between the two groups in favor of the biosimilar medication. This value did not exceed the predefined non-inferiority margin of 0.1. There were no statistically significant differences in relapse rate and systemic and local adverse events of the two groups. The results show that the biosimilar interferon 1-a is non-inferior to the reference product in terms of efficacy while it demonstrates comparable safety. In conclusion the biosimilar interferon 1-a can be considered as an effective and safe alternative to the reference product due to lower cost and more availability.
