Determining Effectiveness of "Off-Label Therapies" for Multiple Sclerosis in a Real-World Setting.
Article in Annals of Indian Academy of Neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo determine the factors, if any, that are associated with the efficacy of "off-label therapies" (OLTs) for multiple sclerosis (MS).
methodsConsecutive patients (N = 174) with relapsing-remitting MS (RRMS) or secondary progressive MS (SPMS) with relapses, on OLTs with a generic formulation of azathioprine, mycophenolate mofetil, or rituximab biosimilar for ≥2 years were included. Annualized relapse rate (ARR) and expanded disability status score (EDSS) 1 year before and ≥2 years after starting OLTs were recorded. Optical coherence tomography (OCT) was done at baseline and at the end of the study.
resultsDuring a median period of 4.1 years (2.4-24), ARR reduced in all (P < 0.0001) and EDSS improved in RRMS (P < 0.0001) patients but not in SPMS (P < 0.31) patients. Good responders were those who had RRMS (P = 0.001, odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.15), female gender (P 0.008, OR 6.67, 95% CI 1.7-26.8), and had early access to OLT (P = 0.006, OR 1.2, 95% CI 1.05-1.40). Baseline peripapillary retinal nerve fiber layer thickness identified the risk of conversion to SPMS (P < 0.01, OR 1.03; 95% CI 1.01-1.06).
conclusionsThis limited prospective study suggests that early identification of patients who could potentially respond to unconventional but accessible therapies may be valuable in the treatment of MS, particularly in resource-poor regions.
