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

backgroundThe efficiency of the target versus sub-target dose of renin-angiotensin system inhibitors (RASIs) in elderly patients with heart failure (HF) with reduced ejection fraction (HErEF) remains unclear.

methodsPubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched from database inception through March 2022 for randomized controlled trials (RCTs) and observational studies considering the effect of the target versus sub-target dose of RASIs on survival in elderly patients (≥ 60 years) with HErEF. The primary outcome was all-cause mortality. The secondary outcomes were cardiac mortality, HF hospitalization, and the composite endpoint of mortality or HF hospitalization. A meta-analysis was conducted to generate combined hazard ratio (HR) and 95% CI.

resultsSeven studies (two RCTs and five observational studies) enrolling 16,634 patients were included. A pooled analysis suggested that the target versus sub-target dose of RASIs led to lower rates of all-cause mortality (HR = 0.92, 95% CI: 0.87-0.98,

conclusionsOur analysis suggests that the target dose of RASIs has a better survival benefit in elderly patients with HFrEF compared to the sub-target dose of RASIs. However, the sub-target dose of RASIs is associated with a similar mortality rate in very elderly patients > 75 years of age. Future high-quality and adequately powered RCTs are warranted.
