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 40-year-old woman presented with intermittent limb weakness, edema, and persistent hypokalemia. She had a history of recurrent urinary tract infections, but no diuretic or laxative use. Laboratory findings revealed metabolic alkalosis with elevated plasma renin activity and aldosterone levels. The urinary electrolyte response to fluid administration suggested pseudo-Bartter syndrome due to the volume depletion. Abdominal imaging revealed renal scarring, suggesting focal renin release from the ischemic regions. This case highlights the importance of recognizing secondary systemic renin-angiotensin-aldosterone system (RAAS) activation driven by focal renin release in renal scarring. This also illustrates a paradox in which salt and water restriction may worsen RAAS-driven hypokalemia.
