Variations in antibiotic use in late preterm and term newborns from 2012 to 2020: a nationwide population-based observational study.

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
objectiveTo quantify regional and unit variations in antibiotic use during the first week of life, incidence of early-onset sepsis (EOS) and mortality in late-preterm and term newborns in Sweden.
designA nationwide cohort study.
settingThe Swedish Neonatal Quality Register, a register of all newborns admitted for neonatal care in Sweden. PATIENTS: All late-preterm and term newborns (≥34 weeks' gestation) admitted to a neonatal unit from 1 January 2012 to 31 December 2020.
main outcome measuresThe proportion of antibiotic use, incidence of EOS and mortality in late-preterm and term newborns.
resultsOut of 1 025 515 newborns, 19 286 neonates (1.9%) received antibiotics with a 2-fold to 5-fold variation across regions (1.3%-3.0%) and units (0.9%-4.3%). Duration of antibiotic therapy (median) varied across regions from 7-10 days for infants with EOS, and 4-7 days for infants with no sepsis. Incidence of EOS ranged from 0.33 to 0.93 per 1000 live births between regions. The number of infants treated per EOS case varied 2-fold to 15-fold across regions (22-39) and units (7-113). All-cause mortality and EOS-associated mortality ranged across regions from 0.21 to 0.54 per 1000 live births and 0.0 to 34.9 (3 of 86 newborns) per 1000 infants with EOS.
conclusionsThis nationwide study revealed wide variations in antibiotic use and in the number of infants treated per EOS case. The results indicate a disproportionate antibiotic use in relation to the incidence of EOS. This emphasises the need for future efforts to minimise unwarranted antibiotic use.
