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

Posterior lumbar subcutaneous edema (PLSE) is often found on MRI in adults with obesity or various lumbar conditions. We report a case of a 6-year-old boy with IgA vasculitis (Henoch-Schönlein purpura) along with PSLE observed on CT and MRI. The finding is markedly rare in patients with IgA vasculitis, with only limited cases previously reported in the literature. The edema was symmetrically localized along the erector spine muscle with a smooth margin. These findings differed from the irregularly accumulated edema observed in some adult cases. PLSE should not be overlooked as a nonspecific finding. When symmetrical and circumscribed PLSE is found in children, IgA vasculitis should be added to differential diagnosis in PLSE.
