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
BACKGROUND AND
objectiveThe impact of lipid abnormalities on right heart function and outcomes in pre-capillary pulmonary hypertension (precPH) remains unclear. This study investigates how lipid profile alterations influence right heart function, strain, and prognosis in precPH patients.
methodsFrom June 2013 to December 2023, 394 precPH patients were prospectively enrolled. Clinical data, cardiac MRI-derived right heart systolic function, and strain parameters were compared among groups based on lipid profiles. The optimal cut-off values of lipid profiles were determined using the maximally selected rank statistics. Prognostic analyses were conducted using Cox regression and Kaplan-Meier survival methods.
resultsDuring a median follow-up of 36 months, 18.8% of patients died. Low-density lipoprotein cholesterol (LDL-C) < 1.93 mmol/L and high-density lipoprotein cholesterol (HDL-C) < 0.82 mmol/L were associated with increased mortality risks (2.51-fold and 2.65-fold, respectively). Multivariate analysis confirmed decreased LDL-C (HR 1.853, 95% CI 1.102-3.115, p = 0.02) and decreased HDL-C (HR 2.019, 95% CI 1.131-3.603, p = 0.02) as independent prognostic indicators. A decrease in either cholesterol subtype predicted worse outcomes (Log-rank p = 0.003). Incorporation of LDL-C and HDL-C enhanced prognostic accuracy of the ESC model (χ
conclusionsDecreased HDL-C and LDL-C levels independently predict increased mortality in precPH patients. Notably, low HDL-C significantly associates with impaired right heart function and strain.
