Outcome Predictors of Generalized Myasthenia Gravis: A Prospective Observational Study.
Article in Annals of Indian Academy of Neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesThere is paucity of studies on long-term remission of autoimmune generalized myasthenia gravis (MG) from Southeast Asia. We report the outcome predictors of generalized MG and also evaluate the influence of high- versus low-dose prednisolone and prednisolone with or without azathioprine (AZA).
methodsFifty-seven patients with generalized MG were included, who completed 2 years of follow-up. Demographic information, comorbidities, Myasthenia Gravis Foundation of America (MGFA) class at baseline and follow-up, acetylcholine receptor (AChR) and muscle-specific kinase antibodies, decremental response, thymectomy, and treatments were recorded. Maximum doses of prednisolone, AZA, and acetylcholinesterase inhibitors were noted. The predictors of MGFA 0 at 3 and 6 months and minimal manifestation (MM) status at 2 years were evaluated.
resultsMGFA 0 was achieved by 27 (47.4%) patients at 3 months, 35 (61.4%) patients at 6 months, and 46 (80.7%) patients at 12 months. At 2 years, 48 (84.2%) patients achieved the MM status and none achieved complete stable or pharmacologic remission. On multivariate analysis, AChR antibody titer (adjusted odds ratio [AOR] 1.08, 95% confidence interval [CI] 1.006-1.167; P = 0.03) and MG activity of daily living (MGADL) at 6 months (AOR 1.28, 95% CI 1.066-1.558; P = 0.01) predicted the MM status. Maximum dose of prednisolone and adjunctive AZA did not predict the MM status.
conclusionsAbout 84.2% of patients with generalized MG, especially those with a low AChR antibody titer and MGADL < 4 at 6 months, achieved the MM status at 2 years.
