1 · What the graph read from it

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.

2 · The registry

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

backgroundCurrent birth-size reference charts for nursery use may inaccurately categorize newborn size, impacting care. We aimed to develop new charts using data from uncomplicated newborns admitted to US nurseries.

methodsWe analyzed de-identified data from newborns admitted to US normal newborn nurseries between 2021 and 2024. Statistical outliers were excluded, and gestational age was recorded in days. Birth weight, length, head circumference, and BMI models were developed by a randomly selected subset and validated by the remaining data. Proportions of newborns below the 10th percentile and above the 90th percentile were compared with the 2010 Olsen and 2013 Fenton charts.

resultsUncomplicated newborns born between 35.0 and 41.6 weeks of gestation were included. The new charts did not exhibit overfitting bias and more accurately identified the expected 10% of newborns below the 10th and above the 90th percentiles compared to existing charts.

conclusionsNew charts (weight, length, head circumference, BMI) improve birth-size referencing in normal newborn nurseries.
