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
introductionThe change in morphology and functions of the right ventricle is an important predictor of heart and lung disease. There is limited data on the normal dimension of the right ventricle. The study aimed to find the right ventricular diameter, its thickness, and tricuspid annular plane systolic excursion in healthy male medical students of a tertiary care hospital.
methodsIt is a descriptive cross-sectional study conducted in healthy medical students of Kathmandu Medical College and Teaching Hospital, from February-April, 2019. Ethical approval was taken from the institutional review committee (reference number 120720193). Convenient sampling method was used. We measured various dimensions of the right ventricle in different views. The data was analyzed in the Statistical Package for the Social Sciences.
resultsIn the 96 male students included in the study, the mean right ventricular basal diameter was 36.45±3.49 mm, right ventricular mid cavity diameter was 29±3.63 mm, right ventricular longitudinal dimension was 65.72±7.52 mm, right ventricular outflow tract in parasternal long-axis view was 27.07±2.12 mm, proximal and distal right ventricular outflow in parasternal short-axis view was 25.33±2.57 mm and 20.08±1.99 mm, right ventricular thickness was 4.20±0.54 mm, and tricuspid annular plane systolic excursion was 23.02±3.54 mm.
conclusionsThe study found that the values of right ventricular dimensions and the right ventricle's tricuspid annular plane systolic excursion among male medical students of a tertiary care hospital to be in accordance with the guidelines by the American Society of Echocardiography. The upper limits of the normal values of the right ventricle could be very helpful in clinical practice in determining the right ventricle dimension.
