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

Prurigo pigmentosa (PP) is a rare inflammatory dermatosis first described in 1971 by Nagashima, classically predominantly affecting young women, particularly those of East Asian descent. Clinically, PP presents with pruritic, erythematous papules, which eventually form a reticulated pattern and resolve into post-inflammatory hyperpigmentation. The exact pathogenesis of PP remains unclear, but it is frequently linked to ketosis-inducing conditions, including strict dieting, fasting, and metabolic changes, such as those observed in diabetic ketoacidosis or anorexia nervosa. In recent years, PP has been increasingly reported in patients undergoing bariatric surgery, likely due to the rapid weight loss and subsequent ketosis that often follow these procedures. This review aims to take a closer and deeper look at the emerging connection between PP and bariatric surgery, particularly laparoscopic sleeve gastrectomy.
