Measuring Children's Knowledge of Acute Rheumatic Fever and Rheumatic Heart Disease: Development and Validation of RHD Knowledge Scale in Nepal.

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
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain significant public health challenges in low- and middle-income countries, including Nepal. This study aimed to develop and validate a tool to assess children's knowledge of ARF and RHD. A 14-item multiple-choice questionnaire was developed through expert consultation and a systematic translation and back-translation process. Content validity was evaluated by 10 experts using item-level and scale-level content validity indices (I-CVI and S-CVI) and the Content Validity Ratio (CVR). A cross-sectional survey of 207 students aged 11 to 16 years was conducted in public schools. Item difficulty and discrimination indices were calculated, and internal consistency was assessed using the Kuder-Richardson Formula 20 (KR-20). Known-groups validity was tested by comparing scores across grades and prior exposure to RHD screening programs. The scale demonstrated excellent content validity (S-CVI/Ave = 0.91) and good internal consistency (KR-20 = 0.772). Item difficulty indices ranged from 0.32 to 0.61, and discrimination indices from 0.23 to 0.36, both within ideal ranges. The mean knowledge score was 6.05 ± 3.43. Higher knowledge scores were observed among older students, those in higher grades, and those previously screened for RHD (
