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
Objective: To validate the General Medication Adherence Scale (GMAS) in Brazilian Portuguese for hypertensive patients. Methods: The GMAS-English was translated into Brazilian Portuguese and adapted for cultural appropriateness by a translation process and expert panel. A cross-sectional study was conducted in northeast Brazilian cardiology divisions of public and private hospitals, interviewing hypertensive patients. Reliability was assessed using Cronbach's alpha, intraclass correlation, and Pearson's correlation. Convergent validity was tested against the BMQ using chi-square. Criterion validity was assessed by comparing GMAS with blood pressure control using chi-square. Results: The GMAS was translated and adapted according to standard procedures. In a validation study with 167 hypertensive patients, Cronbach's alpha was 0.79, and Pearson's correlation showed significant test-retest reliability ( Conclusion: The Brazilian Portuguese version of the GMAS exhibited good consistency and reproducibility, modest agreement with BMQ scale and did not demonstrate acceptable criterion validity for hypertensive patients.
