End tidal carbon monoxide and significant hemolysis.
Review in Journal of perinatology : official journal of the California Perinatal Association, 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
The American Academy of Pediatrics identified significant hemolysis as a significant neurotoxic risk factor for newborns with jaundice in its 2022 guideline for managing hyperbilirubinemia. The guideline recommends starting phototherapy at a lower level than otherwise if significant hemolysis is present. Currently, the optimal way to measure hemolysis is by determining an infant's level of end-tidal carbon monoxide corrected for ambient carbon monoxide (ETCOc). However, it is unclear what the optimal ETCOc level is for determining significant hemolysis. Given the differences in ETCOc levels among infants of different backgrounds, the most reasonable conclusion would be for each unit to determine the mean ± standard deviation ETCOc level of an inclusive group of 200-500 infants in their unit. Each unit could then decide whether to use the 95th, 75th, or some other percentile value as their unit's indicator of significant hemolysis.
