Admission temperature in very preterm infants 2012-2021: a Nationwide Quality Registry Study, Norway.
Article in BMJ paediatrics open, 2025. 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
objectiveTo examine the distribution and time trends of admission temperature in very preterm infants, effects of temperature-preserving interventions and associations between hypothermia and outcomes.
methodsPopulation-based cohort study of infants <32 gestational weeks without lethal malformations admitted to a neonatal intensive care unit within 2 hours of birth between 1 January 2012 and 31 December 2021. Hypothermia was defined as mild (36.0°C-36.4°C), moderate (34.5°C-35.9°C) or severe (<34.5°C). Associations between admission temperature and outcomes were investigated using multivariate logistic regression, adjusting for sex, weight Z-score, gestational age, antenatal steroids, surfactant and hospital.
resultsIn total, 2457/4879 (50.4%) had normal admission temperatures between 36.5°C and 37.5℃, 1314 (26.9%) had mild hypothermia and 886 (18.2%) had moderate to severe hypothermia, with a significant interhospital variance of 7%-40%. Moderate to severe hypothermia decreased from 24% in 2012 to 16% in 2021 (p
conclusionsAlthough the incidence of hypothermia decreased during the study period, it remains a concern due to significant associations with adverse outcomes. Areas for further improvement include addressing interhospital variance and enhancing temperature monitoring in the delivery unit.
