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.

Abstract

aimsEnd-stage renal disease (ESRD) is associated with working memory (WM) impairment. We assessed how structural connectivity (SC), functional connectivity (FC), and structural-functional coupling (SFC) differ between pre-dialysis ESRD (ESRDp), maintenance hemodialysis ESRD (ESRDm), and healthy controls (HCs), and how these changes relate to serum markers and WM performance.

methods29 ESRDp, 29 ESRDm, and 46 HCs completed 0-, 1-, and 2-back tasks, diffusion MRI, and fMRI. WM nodes were defined by overlaying a meta-analytic map with the Harvard-Oxford atlas. SC, FC, and regional SFC were computed among WM-related regions. Group differences, correlations with serum markers, and mediation models were examined.

resultsESRDp showed markedly lower n-back accuracy, longer reaction time (RT), reduced frontoparietal SC, and widespread SFC reductions compared with ESRDm and HCs, whereas ESRDm exhibited near-normal WM performance and partially restored SC/SFC. Elevated urea and lower sodium in ESRDp were associated with weaker SC and altered SFC, which related to poorer accuracy and slower RT; SC and SFC significantly mediated these associations.

conclusionESRDp is characterized by disruption and decoupling of WM networks, while ESRDm is associated with partial network normalization. WM-related SC and SFC combined with serum markers may help identify cognitive vulnerability in ESRD.
