Incidence and Antibiotic Susceptibility of Gram-Negative Bacteria Associated With Chest Infections in Intensive Care Unit Patients From a Selected Hospital in the Kingdom of Saudi Arabia.
Article in BioMed research international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background: Hospital-acquired pneumonia (HAP), including ventilator-associated pneumonia (VAP), is a leading cause of morbidity and mortality in intensive care units (ICUs). Local, organism-specific antimicrobial resistance data are critical to guide empiric therapy and strengthen antimicrobial stewardship efforts. Objective: The aim of this study is to describe the spectrum of Gram-negative bacilli (GNB) responsible for ICU-acquired lower respiratory tract infections (LRTIs) in a Saudi general hospital and to characterize their antimicrobial resistance profiles, including multidrug-resistant (MDR), extensively drug-resistant (XDR), and pandrug-resistant (PDR) patterns. Methods: We retrospectively analyzed 271 nonduplicate GNB isolates recovered from ICU respiratory specimens (sputum, tracheal aspirates, and throat swabs) collected between 2020 and 2022. Demographic characteristics, specimen distribution, bacterial species, and antimicrobial susceptibility patterns were summarized. MDR, XDR, and PDR classifications were determined according to standard phenotypic criteria. Results: Of the 271 specimens, 126 (46%) were sputum, 108 (40%) were tracheal aspirates, and 37 (14%) were throat swabs. Patients were 52% male (141/271) and 48% female (130/271), with 56% aged > 65 years. Twenty-three GNB species were identified; the predominant pathogens were Conclusions: ICU cohort is dominated by a limited number of highly resistant GNB led by
