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

Background: Neonates born small for gestational age (SGA) are at an increased risk of multiple severe complications, including infections. This suggests that immune cells and other peripheral blood cells may be affected. Purpose: Here we aimed to investigate whether SGA severity affects complete blood count and leukocyte differentiation of preterm neonates with a gestational age (GA) of <35 weeks and identify clinical factors that influence cell counts. Methods: This retrospective cohort study investigated the complete blood count sampled within 72 hours after birth in 1,940 preterm neonates admitted to the neonatal intensive care unit of Leiden University Medical Center. The neonates were divided into extreme SGA (<3rd birth weight percentile), moderate SGA (>3rd to <10th birth weight percentile), and controls (>10th birth weight percentile). Results: After multivariate analysis, extremely SGA neonates showed significantly decreased neutrophil, monocyte, lymphocyte, and thrombocyte counts. Thrombocyte counts were significantly lower in moderately SGA neonates than controls. In contrast, SGA status had no significant effect on erythrocyte count or hemoglobin concentration. Conclusion: Blood cell counts of extremely SGA neonates were decreased, mainly in the white blood cell line. The mechanisms underlying these decreased counts in SGA infants, especially their clinical effects, remain unclear.
