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

Objective: The reported incidence of delirium in hospitalized heart failure (HF) patients in current studies was inconsistent. The objective of this study was to conduct a meta-analysis to quantify the incidence of delirium in hospitalized HF patients. Methods: PubMed, The Cochrane Library, Web of Science, Embase, Ovid Medline, CINAHL, CNKI, WanFang Database, VIP, and SinoMed were systematically searched from inception to 18 May 2026. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias. Stata 18.0 was used for statistical analysis. The meta-analysis employed a random-effects model with the DerSimonian-Laird method to pool the incidence of delirium in hospitalized HF patients. Subgroup analysis, sensitivity analysis, and meta-regression analysis were undertaken to identify the sources of heterogeneity. Results: Ultimately, 17 studies met the inclusion criteria, including a total of 17,944 HF patients. The meta-analysis results showed that the pooled incidence of delirium in hospitalized HF patients was 18.5% (95% confidence interval: 13.1%-24.6%; Conclusion: Incident delirium in patients hospitalized for HF is common, affecting nearly one in five patients. Subgroup analysis identified potential factors influencing delirium onset in hospitalized HF patients. Despite the substantial heterogeneity across estimates, these findings underscore the need for systematic screening and routine assessment of delirium during hospitalization.
