1 · What the graph read from it

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.

2 · The registry

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

backgroundCongenital heart disease (CHD) is a leading cause of pediatric morbidity and mortality worldwide. The genetics of CHD in African populations is not well understood, although it has been shown in other settings that a genetic diagnosis can have implications for patient management and risk stratification. In this study, we aimed to identify pathogenic and likely pathogenic (P/LP) variants in a cohort of patients with CHD from Southern Africa.

methodsExome sequencing was used to screen 356 patients with diverse cardiac phenotypes from South Africa and Namibia.

resultsA P/LP variant was identified in 28 patients (7.9%). Analysis of 11 parent-child trios revealed a further LP variant in

conclusionsTogether, these data confirm a role for rare deleterious variation in nonsyndromic CHD and demonstrate that a P/LP variant can be identified in 8% of patients from Southern Africa.
