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

backgroundType 2 diabetes mellitus (T2DM) is known to worsen the prognosis of heart failure (HF), but its specific impact on patients with ischemic versus non-ischemic heart failure with mildly reduced ejection fraction (HFmrEF) remains unclear due to limited research and conflicting evidence.

methodsWe conducted a retrospective study of 1,691 HFmrEF patients at Xiangtan Central Hospital. Participants were divided into four groups: ischemic with T2DM (467 patients), ischemic without T2DM (856 patients), non-ischemic with T2DM (87 patients), and non-ischemic without T2DM (281 patients). We utilized the Cox proportional hazards model to analyze differences in all-cause mortality and cardiovascular events among the groups.

resultsAfter adjusting for multiple confounding factors using the Cox proportional hazards model, the ischemic heart disease and T2DM group had a significantly higher risk of all-cause mortality compared to the ischemic group without T2DM (HR = 1.5, 95% CI = 1.2-1.9, P = 0.001). The risk of cardiovascular events was also significantly increased (HR = 1.3, 95% CI = 1.1-1.5, P = 0.001). In non-ischemic HFmrEF patients, T2DM was not associated with a significantly increased risk of all-cause mortality (HR = 1.0, 95% CI = 0.6-1.7, P = 0.957) or cardiovascular events (HR = 1.3, 95% CI = 0.9-1.9, P = 0.113).

conclusionT2DM significantly increases the risk of all-cause mortality and cardiovascular events in ischemic HFmrEF patients, while its impact on non-ischemic HFmrEF patients is limited. These findings underscore the importance of managing T2DM in patients with ischemic HFmrEF.
