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

backgroundHeart failure (HF) is among the cardiovascular diseases with high morbidity and mortality worldwide. Due to the high burden of HF, finding easy-to-use prognostic factors has become important. Studies have investigated the correlation between anion gap (AG) and the HF prognosis. In this systematic review and meta-analysis, we aimed to evaluate the association between AG association with HF prognosis.

methodsPubMed, Embase, Scopus, and the Web of Science were systematically searched for studies evaluating AG in HF prognosis. Standardized mean difference (SMD) and pooled hazard ratio (HR) in addition to 95% confidence intervals (CIs) were calculated using random-effect meta-analyses to compare survivors vs. non-survivors.

resultsNine studies were included in this systematic review. In a random-effect meta-analysis comparing AG levels in those who died and survivors, non-survivors had significantly higher levels of AG (SMD 0.57, 95% CI 0.42 to 0.71, P < 0.0001, I

conclusionThis study found that higher AG levels are associated with higher mortality in patients with HF which could be used in clinical settings and for patient management due to its ease of measurement and calculation. If confirmed in future studies, using this easy-to-measure index in clinical settings could provide useful information for clinicians in determining the risk of HF patients. CLINICAL TRIAL NUMBER: Not applicable.
