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

Rationale & Objectives: Cognitive function is impaired in patients with chronic kidney disease, particularly in those undergoing hemodialysis, although the precise mechanisms are not well understood. This cross-sectional study examined the possible relationship between serum electrolyte levels and cognitive function in patients receiving maintenance hemodialysis. Study Design: Cross-sectional study. Settings & Participants: Eligible patients were selected from the participants of the Osaka Dialysis Complication Study, a multicenter study conducted in Japan. Exposures: Serum sodium, potassium, and chloride levels. Outcomes: Cognitive function assessed by the Modified Mini-Mental State examination (3MS) which was mathematically transformed to 3MS' to follow a normal distribution. Analytical Approach: Multivariable-adjusted linear regression analysis. Results: For this study, 1,207 patients were selected. Their median age, 3MS score, serum sodium, potassium, and chloride concentrations were 67 (IQR, 60-74) years, 91 (IQR, 82-97) points, 139 (IQR, 137-141) mEq/L, 4.7 (IQR, 4.2-5.2) mEq/L, and 102 (IQR, 99-105) mEq/L, respectively. After adjustment, sodium ( Limitations: Causality cannot be determined because of the cross-sectional design. Conclusions: This study revealed that serum chloride level was a novel factor independently associated with cognitive performance in patients on maintenance hemodialysis, suggesting an unrecognized role of chloride in cognition.
