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

Patients with heart failure with preserved ejection fraction (HFpEF) often experience dyspnea, decreased exercise tolerance, and decreased quality of life (QOL). Exercise training is a promising non-pharmacological treatment, with some improvement in exercise tolerance and QOL in HFpEF patients in randomized controlled trials (RCTs). We conducted a systematic review and meta-analysis of RCTs examining the effect of exercise therapy on exercise tolerance, QOL, and echocardiographic parameters in patients with HFpEF. Article database search of PubMed, Embase, and Cochrane Central Register of Controlled Trials identified 15 publications representing 579 unique patients. Results are presented as weighted mean difference (WMD) with 95% confidence intervals (CI). Exercise training (compared to control) demonstrated a significant improvement in exercise tolerance as measured by peak absolute VO2 (WMD [95% CI] = 164.67 [65.54, 263.79] mL/min), peak relative VO2 (WMD [95% CI] = 1.85 [0.98, 2.73] mL/min/kg), workload (WMD [95% CI] = 12.92 [4.67, 21.17] W), exercise time (WMD [95% CI] = 2.05 [1.57, 2.53] min), anaerobic threshold (WMD [95% CI] = 170.31 [35.40, 305.22] mL/min/kg), and 6-min walk test distance (WMD [95% CI] = 32.77 [20.72, 44.83] m); in QOL as measured by Short Form (SF-36) physical functioning domain (WMD [95% CI] = 9.95 [2.85, 17.05]) and SF-36 vitality domain (WMD [95% CI] = 6.24 [0.15, 12.34]); and in the echocardiographic measure of LVESD (WMD [95% CI] =  - 0.16 [- 0.28, - 0.04] cm). In conclusion, we found after systematic review and meta-analysis of RCTs that exercise therapy improves exercise tolerance and physical-related quality of life measures.
