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

A medical case report is a form of scholarly writing describing unique clinical vignettes that offer important learning points in patient management and generate hypotheses to spur further research. Despite its long-standing tradition dating back to 400-1600 BC, the case report has fallen out of favour in modern medical journals due to perceived lower status in the evidence hierarchy and concerns of limited citation potential affecting journal impact factors. In this commentary, we argue for the enduring relevance of case reports in contemporary medical practice, specifically in four main areas: (1) serving as catalysts for scientific discovery, (2) contributions to clinical diagnosis/management, (3) educational value in cultivating clinical reasoning skills and (4) accessibility as a scholarly design for junior medical trainees. We then describe practical strategies for medical trainees and practitioners pertaining to case selection, consent-taking processes, co-author inclusion and writing styles to improve the chances of successful case report publication.
