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 incidence of cognitive impairment in patients with peritoneal dialysis (PD) and hemodialysis (HD) has been increased, but the specific mechanism is not clear. Disruption of iron homeostasis is associated with cognitive impairment. This study aimed to explore the relationship between brain iron deposition and cognitive impairment in patients with PD and HD by using quantitative susceptibility mapping (QSM).

methodsThe cross-sectional study enrolled 56 PD patients, 66 HD patients, and 56 age-sex matched healthy controls. All participants underwent QSM to measure brain iron content and Montreal Cognitive Assessment (MoCA) to assess cognitive function. In addition, relevant biochemical indicators were collected and analyzed. The ANOVA was used to test for differences in susceptibility value among bilateral caudate nuclei (CAU), thalamus (THA), putamen and pallidum. Pearson correlation analysis was performed to investigate the relationships between susceptibility value and clinical laboratory parameters or MoCA score.

resultsCompared with HC, PD patients showed higher susceptibility value in bilateral CAU and left THA. Compared with HD patients, PD patients showed higher susceptibility value in left THA. PD patients showed a negative correlation between susceptibility value and MoCA score.

conclusionThere are different patterns of brain iron deposition in PD and HD patients. Abnormal brain iron deposition in PD patients may be associated with cognitive impairment.
