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
introductionHospital-acquired pneumonia (HAP) is a major type of hospital-acquired infection with substantial morbidity. Large-scale epidemiological data on HAP in China remain limited. This multi-center retrospective study investigates the epidemiology, etiology, and risk factors of HAP to support clinical management.
methodsFrom January to December 2019, 543 patients from 37 tertiary hospitals meeting the enrollment criteria (who meet the diagnosis of HAP according to the Guidelines for the Diagnosis and Treatment of HAP in Adults in China and have clear clinical outcomes) were included. Patient data were retrospectively analyzed.
resultsThe study recorded 15.8% overall mortality. Multivariate analysis identified independent risk factors including secondary ventilator-associated pneumonia, admission to the intensive care unit, positive airway secretion culture, liver dysfunction, heart failure, cancer, long-term catheter indwelling, sequential organ failure assessment (SOFA) score >2 and quick SOFA (qSOFA) score >1 (p < 0.05). The top four pathogens of HAP were Acinetobacter baumannii (24.89%), Klebsiella pneumoniae (21.57%), Pseudomonas aeruginosa (13.73%), and Staphylococcus aureus (5.88%).
conclusionGiven the high mortality rate associated with HAP, prevention and early diagnostic assessment of HAP during hospitalization are paramount for these patients. The main pathogens of HAP are Gram-negative bacteria, which frequently exhibit substantial antimicrobial resistance. Therefore, antibiotics should be selected carefully.
