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

Background: Long QT syndrome is clinically associated with recurrent ventricular tachycardia and sudden cardiac death. Mutations in Objective: We aimed to investigate the pathogenicity and personalized therapy for a patient with LQTS2 carrying a novel Methods: This study aimed to evaluate the expression and function of the channel protein, we conducted immunoblotting and whole-cell patch-clamp recordings. In addition, patient-specific human-induced pluripotent stem cell-derived cardiomyocytes were combined with a heart-on-chip platform to validate the pathogenicity of this heterozygous variant and investigate the pharmacologic candidates for phenotypic rescue. Results: In HEK293 cells overexpressing the mutant Conclusion: The F431L mutation in
