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: Compliance with health-related behaviors is a dilemma among heart failure (HF) patients. The present study aimed to assess the validity and reliability of a Persian translation of the revised heart failure compliance questionnaire (RHFCQ) in Iranian HF sufferers. Methods: This methodological study was performed on outpatient HF individuals referred to a heart clinic in Isfahan, Iran. The forward-backward translation method was used for translation. Twenty subjects were invited to express their opinions on the provided items concerning simplicity and understandability. Twelve experts were invited to rate the items regarding the content validity index (CVI). Cronbach's α was used to evaluate internal consistency. The patients were asked to complete the questionnaire for the second time after 2 weeks to investigate test-retest reliability using the intraclass correlation coefficient (ICC). Results: There were no obvious difficulties during the translation and assessment of the simplicity and comprehensiveness of the questionnaire items. The CVI of the items ranged from 0.833 to 1.000. Totally, 150 patients (age: 64.60±15.00 y, males: 58.0%) filled in the questionnaire twice with no missing data. The highest and lowest compliance rates were attributed to alcohol and exercise domains, respectively (83.00±7.70% and 45.55±12.00%, respectively). Cronbach's α was 0.629. After the omission of 3 items related to smoking and alcohol cessation, Cronbach's α rose to 0.655. The ICC showed an acceptable value of 0.576 (95% CI, 0.462 to 0.673). Conclusion: The modified Persian RHFCQ is a simple and meaningful tool with acceptable moderate reliability and good validity for assessing compliance in Iranian HF patients.
