The effect of incubator humidity on morbidity and mortality in preterm infants: a systematic review.
Synthesis in BMC pediatrics, 2025. 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
purposeTo assess the association between different incubator humidity levels and clinical outcomes in preterm infants.
backgroundSince there is no well-accepted standard for delivery of incubator humidity for preterm infants. A meta-analysis is needed to summarize the status of current research.
methodsDatabases searched included PubMed, MEDLINE, the Cochrane Library, Embase, Ovid, Google scholar and Web of Science, published between January 2000 and December 2023. Randomized control trials, prospective cohort studies and retrospective cohort studies were included if they assessed how different incubator humidity levels affected preterm infants with a gestational age < 34 weeks, published in English. Infection rates, the incidence of bronchopulmonary dysplasia and predischarge mortality were evaluated.
resultsIncluded in this review were 3 randomized control trials and 3 cohort studies including 801 preterm infants. Findings revealed that a high humidity level increased the incidence of infection in preterm infants (RR = 1.26, 95% CI 1.02, 1.55, P = 0.03). No significant difference was found between a high incubator humidity level and the incidence of bronchopulmonary dysplasia or infant mortality.
conclusionsThis study found that high humidity levels had a significant impact on the incidence of infection. Current evidence is limited by signifcant heterogeneity across studies, lack of data related to regarding the effects of factors such as humidity duration and humidity adjustment schemes on the outcomes.
