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
aimsThis study aimed to translate and validate the Persian version of the Global Sleep Assessment Questionnaire (GSAQ) in patients with chronic obstructive pulmonary disease (COPD) to screen for sleep disorders.
methodsAfter obtaining permission from the original developers, the English version of GSAQ was translated into Persian. Ten sleep medicine experts assessed the face and content validities of the Persian GSAQ. After that, 20 patients with COPD and different literacy and socioeconomic status were interviewed to evaluate face validity. For evaluation of internal consistency (by Cronbach's alpha), reliability (by test-retest reproducibility after 2-4 weeks), and construct validity, 50 consecutive patients with COPD were enrolled in the study. Construct validity, using convergent and divergent validity, was evaluated by examining Pearson correlation coefficients between GSAQ scales, the Pittsburgh Sleep Quality Index (PSQI), and the Saint George Respiratory Questionnaire (SGRQ).
resultsGSAQ was successfully translated into Persian. The overall mean score of GSAQ was 9.36 ± 13.52. The internal consistency of the Persian GSAQ was acceptable (Cronbach α = 0.73), and the calculated intra-class-correlation (ICC) value was 0.82. The Pearson R coefficient was 0.72 between GSAQ and PSQI and 0.77 between GSAQ and SGRQ, implying a significant relationship (p < 0.001).
conclusionThe Persian version of GSAQ is a valid and reliable questionnaire for screening sleep disorders in Persian-speaking individuals with COPD.
