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

Purpose: The relationship between increased right ventricular (RV) afterload (moderate-to-high suspicion of pulmonary hypertension indicated by echocardiography) and the prognosis of patients hospitalized with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is not yet well understood. Patients and Methods: This prospective cohort study was conducted in 11 hospitals from 2017 to 2020, involving patients hospitalized with AECOPD. Echocardiography was performed within 48 hours of admission. Patients were classified into two groups: those with increased RV afterload (n=237) and those with normal RV afterload (n=415). Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox regression analysis to evaluate the impact of RV afterload on patient outcomes. Kaplan-Meier survival curves were employed to assess the association between RV afterload and 3-year all-cause mortality. Results: Kaplan-Meier survival curves demonstrated that the 3-year all-cause mortality rates were 22.8% in AECOPD patients with increased RV afterload and 9.5% in those with normal RV afterload. Cox regression analysis indicated that increased RV afterload is an independent predictor of poor prognosis in hospitalized AECOPD patients, significantly increasing the risk of 3-year all-cause mortality (HR=2.172, 95% CI: 1.384-3.411; Conclusion: Increased RV afterload is associated with a significant increase in the risk of 3-year all-cause mortality in patients hospitalized with AECOPD, posing a 2.2-fold higher risk compared to those with normal RV afterload. It also stands as an independent risk factor for mortality. Elevated BNP or NT-proBNP levels and reduced BMI are additional independent risk factors of mortality. Early detection of these three risk factors could play a role in stratifying high-risk patients, guiding clinical decision-making, and improving patient outcomes in AECOPD.
