Risk factors and prognosis of pulmonary infection in hepatitis B-related acute-on-chronic liver failure: a retrospective cohort study.

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
objectiveTo identify risk factors for pulmonary infection in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), assess its impact on prognosis, and develop a prognostic prediction model.
methodsWe retrospectively analyzed the clinical data of 393 patients with HBV-ACLF. Logistic regression was used to analyze the risk factors for lung infection in ACLF patients, as well as the factors affecting the prognosis of those who were infected. Additionally, a prognostic prediction model was established using the Nomogram method.
resultsThe incidence of pulmonary infections in patients with ACLF was 38.7%, and patients with ACLF combined with pulmonary infections had a higher short-term mortality rate than those without infections (65.71% vs. 35.02%). Multivariate logistic regression analysis indicated that independent risk factors for pulmonary infection included TBIL, CRP, invasive procedures, peritoneal effusion, and hepatic encephalopathy. Additionally, creatinine, INR, comorbid diabetes mellitus, neutrophil counts, and lymphocyte counts were identified as independent risk factors affecting 30-day mortality in patients with pulmonary infection. Incorporating these risk factors, a new predictive model was established, with an area under the receiver operating characteristic curve of 0.832 (95% CI, 0.765-0.900). This model demonstrated higher discriminatory performance compared to traditional prognostic models such as CTP, MELD, and MELD-Na, with statistically significant differences (P < 0.05).
conclusionHBV-ACLF patients are susceptible to pulmonary infection, with fungal infection posing a significant threat. Pulmonary infection is associated with worse prognosis in HBV-ACLF patients. Early identification of risk factors and prognostic assessment can facilitate timely intervention and improve prognosis.
