Hungarian Validation of the Individualized Neuromuscular Quality-of-Life Questionnaire (INQoL) in Adult Patients with Muscular Diseases.
Article in Neurology international, 2026. 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
methodsAccording to the widely accepted method of validation, we first translated the original INQoL version into Hungarian, and then a native English speaker translated it back into English to test its validity. Following a pretest procedure, the INQoL was administered to 80 patients with various muscular diseases and 30 age-matched controls. The internal consistency and test-retest reliability were assessed. Concurrent validity was measured using the 36-item Short Form Survey (SF-36) questionnaire.
resultsFor all INQoL subscales, Cronbach's alpha was above 0.7, demonstrating the reliability of the subscales. The highest Cronbach alpha value was for the Weakness subscale (0.983) and the lowest for the Treatment subscale (0.794). The intraclass correlation coefficient test values ranged from 0.810 (Treatment) to 0.988 (Pain), indicating excellent test-retest reliability. There was a strong correlation between the SF-36 Physical Function and multiple INQoL subscales, including Weakness (r = 0.754,
conclusionsOur findings indicate that the Hungarian-language adaptation of the questionnaire possesses adequate reliability and construct validity for assessing the quality of life in patients with muscular disorders.
