Late-Onset Sepsis Among Extremely Preterm Infants During the COVID-19 Pandemic.
Article in Pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesTo compare incidence of late-onset sepsis (LOS) among extremely preterm infants before and during the COVID-19 pandemic.
methodsMulticenter cohort study of infants with birthweight 401 to 1000 g or gestational age 22 to 28 weeks. LOS was defined as a bacterial or fungal pathogen isolated from blood or cerebrospinal fluid culture obtained after 72 hours of age. Primary outcome was LOS incidence calculated as incidence proportion (LOS cases among all admissions) and incidence rate (LOS events/1000 patient days). A multivariable Poisson regression model was used to compare the adjusted risk of LOS incidence proportion before (1/1/18-3/31/20) and during the pandemic (4/1/20-12/31/21). An interrupted time series analysis using a generalized linear mixed model with center as a random effect was used to compare LOS incidence rates during the 2 periods.
resultsAmong 6509 eligible infants, LOS incidence proportion was not different before (18.2%) and during the pandemic (16.9%; P = .18). The adjusted relative risk (95% CI) for LOS was 0.93 (0.82-1.05) and for LOS or mortality was 0.98 (0.88-1.08) during the pandemic compared to the period before the pandemic. In the interrupted time series analysis, there was no significant change in LOS incidence rates at the start of the pandemic (0.219, 95% CI, -0.453 to 0.891) or microbiology of LOS, and change in trends of LOS incidence rates before and during the pandemic was not significant (-0.005, 95% CI, -0.025 to 0.015).
conclusionsIn a large multicenter study of extremely preterm infants, rates of LOS remained unchanged during the pandemic.
