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

backgroundThe interplay between cardiac and kidney functions is mediated by the autonomic nervous system. Cardiovascular autonomic neuropathy (CAN) is a well-documented dysfunction of this system, with heart rate variability (HRV) serving as the principal diagnostic tool. CAN is recognized as a prognostic marker for adverse kidney outcomes in diabetic kidney disease (DKD). However, the pathogenesis of CAN in patients with nondiabetic chronic kidney disease (CKD) remains underexplored. This study elucidated the prevalence of CAN and its clinicopathologic characteristics in patients with nondiabetic CKD.

methodsThis cross-sectional analysis evaluated 165 nondiabetic CKD patients who underwent kidney biopsy from 2020 to 2023. HRV was quantified using the coefficient of variation of the RR interval (CVRR). CAN was diagnosed based on the CVRR and defined using the CVRR reference value-derived by defining the age and sex-dependent lower normal limits as the 2.5 percentile point of the distribution of the CVRR values in healthy individuals.

resultsThe median patient age was 47.0 (34.0-57.0) years, and 50.9% were male. The median estimated glomerular filtration rate was 65.0 (42.0-85.0) mL/min/1.73m

conclusionsThe prevalence of CAN diagnosed using the CVRR in this nondiabetic CKD cohort was 9.7%, which is four times higher than that in healthy individuals. Nondiabetic CKD patients with CAN was associated with advanced IF/TA.
