The underestimated burden of postoperative pulmonary complications in emergency laparotomy: a propensity score-matched analysis.

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
Introduction: Emergency laparotomy (EL) remains one of the highest-risk procedures in general surgery, characterized by substantial postoperative morbidity and mortality. Despite major advances in perioperative medicine, current enhanced-recovery and infection-prevention protocols are largely derived from elective surgical cohorts and are seldom validated in emergency settings. This lack of EL-specific data represents a critical gap in establishing evidence-based perioperative guidelines for this uniquely vulnerable patient population. Among postoperative complications, pulmonary complications (PPCs) are the most frequent and consequential, affecting 20-40% of patients and significantly impairing recovery and survival. This study aimed to identify preoperative predictors of PPCs and their impact on postoperative mortality, highlighting potentially actionable targets within the constraints of emergency surgical care. Methods: A total of 928 EL patients were analyzed. To control for non-modifiable demographics and comorbidities, propensity score matching generated two cohorts of 328 patients each-those with and without PPCs. Univariate and multivariate logistic regression identified independent preoperative predictors of PPCs, and survival analyses assessed their association with postoperative mortality. Results: Mortality was significantly higher in patients with PPCs (42.1%) than in those without (11.9%). Independent preoperative predictors of PPCs included ASA score ( Conclusion: PPCs are the most frequent and deadly complications following EL, and their occurrence substantially worsens survival. Among identified predictors, Gram-negative MDRO colonization represents the most clinically actionable target. Tailoring empiric antibiotic therapy for high-risk, colonized EL patients could represent a pivotal step toward evidence-based, condition-specific perioperative guidelines aimed at reducing pulmonary complication-related mortality.
