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

Cognitive impairment is common in maintenance hemodialysis, but practical risk-assessment tools remain limited. We evaluated the association between baseline serum brain-derived neurotrophic factor (BDNF) and 1-year screening-defined incident cognitive impairment and examined whether BDNF added predictive information beyond routine clinical, laboratory, and baseline cognitive variables. This single-center prospective cohort included 130 maintenance hemodialysis patients with baseline Montreal Cognitive Assessment (MoCA) scores ≥26. The primary outcome was screening-defined incident cognitive impairment, defined as follow-up MoCA <26. Serum BDNF was measured by enzyme-linked immunosorbent assay. Five models were assessed using repeated 5-fold cross-validation; repeated nested cross-validation was added as a sensitivity analysis. During follow-up, 70 patients (53.8%) met the screening-defined outcome. Each 1-SD higher BDNF level was associated with lower odds of the outcome [adjusted OR, 0.52 (95% CI, 0.34-0.80);
