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

The spot urinary potassium-to-creatinine (uK/uCr) ratio has been proposed as a surrogate for 24-h potassium excretion, but its clinical determinants and prognostic significance in heart failure (HF) remain unclear. We evaluated the clinical variables associated with the uK/uCr ratio and its relationship with long-term mortality in ambulatory HF patients. We ambispectively analyzed 1,145 patients from a single-center HF clinic. A multivariable linear regression model was used to identify factors independently associated with the uK/uCr ratio, and Cox models assessed its prognostic value. Mean age was 73.2 ± 11.3 years, 41.5% were women, and 52.0% had HF with preserved ejection fraction. Median NT-proBNP and uK/uCr were 1324 (447-2952) pg/mL and 48 (36-62) mmol/g creatinine, respectively. Higher uK/uCr was independently associated with estimated glomerular filtration rate (28.3% of R
