Analysis of factors associated with severe disease and construction of a monogram for elderly patients with community-acquired pneumonia complicated by heart failure.

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
Objective: To identify independent influencing factors of severe disease among old community-acquired pneumonia(CAP) patients complicated by heart failure(HF), and to establish the nomogram model for identifying severe illness early in clinical settings. Methodology: This was a retrospective study. Altogether 140 elderly patients with concurrent CAP and HF admitted into Baoding No.1 Central Hospital between January 2022 to November 2025. According to the CURB-65 (confusion, blood urea nitrogen, respiratory rate, systolic blood pressure, age ≥65 years) score, patients were classified as the non-high-risk( Results: After preliminary screening through univariate analysis, multivariate logistic regression identified procalcitonin(PCT), B-type natriuretic peptide(BNP), and impaired consciousness as independent predictors of severe disease( Conclusion: The nomogram model incorporating PCT, BNP, and impaired consciousness demonstrates greater predictive power than those using any single parameter alone. With good calibration and favorable clinical utility.
