Healthcare utilisation among mothers of newborns with invasive group B
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveLong-term healthcare utilisation (HCU) among mothers of infants with neonatal, invasive group B
designCohort study.
settingPopulation of Denmark.
participants1565 mothers of infants with iGBS and 44 976 matched comparators from 1997 through 2021, with follow-up until 2022, using national health and social registry data. PRIMARY AND SECONDARY OUTCOME MEASURES: HCU including primary, inpatient, outpatient, psychiatric and surgical care was evaluated as period prevalence ratio (PPR) and rate ratios compared across three time periods (0-6 years, 7-13 years and 14-20 years) using a modified Poisson regression model and negative binomial regression with 95% CIs.
resultsMothers of newborns with iGBS had higher PPRs of psychiatric care contacts in the first 0-6 years and 14-20 years following iGBS compared with the comparison cohort (RR
conclusionMothers of iGBS-exposed infants had elevated psychiatric healthcare use and increased primary, and outpatient care visits compared with matched comparators, suggesting heightened healthcare needs and psychosocial burden of caregiving up to 20 years post-iGBS.
