Difference in risk profiles for pulmonary hypertension between non-elderly and elderly patients undergoing maintenance hemodialysis.
Article in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundPulmonary hypertension (PH) is highly prevalent and associated with increased mortality in patients undergoing maintenance hemodialysis (MHD). This study aimed to explore the disparities in the prevalence, risk factors, and prognostic impacts of PH between non-elderly and elderly MHD patients.
methodsThis study included 179 MHD patients with complete clinical records. All patients were evaluated using Doppler echocardiography, and PH was defined as a pulmonary artery systolic pressure > 35 mmHg.
resultsThe prevalence rates of PH were 24.8% in non-elderly patients and 33.8% in elderly patients. Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) was a predominant risk factor for PH in hemodialysis patients. A lower ratio of uric acid to high-density lipoprotein (UHR) was associated with PH among non-elderly patients, whereas diabetes mellitus served as a specific risk factor for elderly patients. The areas under the receiver operating characteristic curves of these risk factors identified in non-elderly and elderly patients were 0.86 (bootstrap 95% confidence interval (CI) 0.78-0.93) and 0.90 (bootstrap 95% CI 0.82-0.97), respectively. During a median follow-up duration of 32.90 (4.00-61.50) months, the presence of PH notably elevated the risk of all-cause mortality and cardiovascular hospitalization in both non-elderly and elderly patients. Meanwhile, it significantly augmented the risk of all-cause hospitalization (HR: 2.24, 95% CI 1.26-3.98, P = 0.006) in the non-elderly.
conclusionsDistinct risk profiles for PH were identified between non-elderly and elderly MHD patients, offering valuable clinical data for the development of early detection and prevention strategies based on age stratification.
