Sex-specific differences in risk factors and outcomes for long-term mechanical ventilation: a longitudinal cohort analysis of claims data.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05260853 (Early Detection and Early Intervention Program in High-risk Patients to Avoid Invasive Long-term Ventilation - Prevention of Invasive Ventilation - PRiVENT), which is not on this 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.

Abstract
Sex differences in intensive care medicine, particularly regarding risk factors for (MV), are underexplored. This study aimed to investigate sex-related risk factors for long-term MV. We analyzed claims data from patients aged ≥ 30, with at least one comorbidity, who received MV (≥ 96 h) between 2015 and 2018. Data covered 365 days prior to hospitalization and 30 days post-discharge. Sex differences in 29 predefined risk factors were assessed. Over 12,000 hospitalizations were analyzed, with 37.8% of patients being female. Women were older (71.3 ± 11.6 vs. 69.9 ± 11.2 years, p < 0.001) and more often transferred from nursing homes (4.5% vs. 2.7%, p < 0.001). Men required invasive long-term ventilation more often (33.8% vs. 31.2%, p = 0.004) and had more ventilation hours (400.0 ± 377.9 vs. 373.0 ± 341.8, p < 0.001). Among pre-existing conditions, women had more thyroiditis and rheumatic mitral valve disease, while men had more COPD, cardiac arrhythmia, eating disorders, and acute pancreatitis. Men were more likely to undergo bronchoscopy, autologous blood transfusion, or Extracorporeal life support (ECLS) within 96 h of MV. Multivariate analyses revealed stronger associations between certain risk factors and long-term MV by sex. For men, thyroiditis (OR 2.7 vs. 1.4 in women), cerebral infarction (OR 2.3 vs. 1.4), and acute pancreatitis (OR 3.2 vs. 1.0) were more strongly linked to weaning failure. For women, cerebrospinal fluid surgery (OR 5.7 vs. 2.0 in men) and acute pancreatitis (OR 4.7 vs. 3.0 in men) had stronger associations with long-term MV. ECLS and eating disorders were only linked to long-term MV in men. This study highlights sex differences in risk factors and outcomes for long-term MV, suggesting the need for sex-specific management strategies.Trial registration: The PRiVENT study was retrospectively registered at ClinicalTrials.gov (NCT05260853).
