Association of early antibiotic therapy and in-hospital mortality in adult mild-to-moderate acute aspiration pneumonitis: a cohort study.
Article in Internal and emergency medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPatients with aspiration pneumonitis often receive empiric antibiotic therapy despite it being due to a non-infectious, inflammatory response.
objectiveTo study the benefits of early antibiotic therapy in patients with suspected aspiration pneumonitis in an acute care hospital.
designRetrospective cohort study using electronic medical records from Teine Keijinkai Hospital.
participantsAdults aged over 18 years admitted with a diagnosis of aspiration pneumonitis to the Department of General Internal Medicine or Emergency Department between January 1, 2008, and May 31, 2019. A diagnosis of aspiration pneumonitis was defined as a documented macro-aspiration event and a chest radiograph demonstrating new radiographic infiltrates. MAIN MEASURES: Patients were classified into the "early antibiotic treatment" group and the "no or late treatment" group depending on whether they received antibiotic therapy for respiratory bacterial pathogens within 8 h of arrival. The primary outcome was in-hospital all-cause mortality. Secondary outcomes included length of hospital stay, antibiotic-free days, duration of fever, readmission within one month, and incidence of complications. KEY
resultsOf the 146 patients enrolled, 52 (35.6%) did not receive early antibiotic therapy, while the remaining 94 (64.4%) did. There was no difference in in-hospital mortality rates between the groups after adjustment for potential confounding variables using Cox proportional hazards analysis (hazard ratio 2.78; 95% confidence interval, 0.57-13.50, p = 0.20). Patients in the no or late treatment group had more antibiotic-free days (p < 0.001) and a shorter length of hospital stay among survivors (p = 0.040) than did those in the early antibiotic treatment group. There were no statistically significant differences between the groups with respect to other secondary outcomes.
conclusionsEarly antibiotic therapy for acute aspiration pneumonitis was not associated with in-hospital mortality, but was associated with a longer hospital stay and prolonged use of antibiotics.
