Complete blood count reference intervals for extremely preterm neonates.
Article in European journal of pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Preterm infants exhibit dynamic hematological profiles during the first postnatal days, necessitating robust reference intervals for clinical interpretation. The aim of this study is to establish comprehensive reference intervals for complete blood counts in preterm neonates during the first five postnatal days, stratified by gestational age and postnatal age. Data from preterm neonates (23 + 0-34 + 0 weeks gestation) admitted to the neonatal intensive care unit Graz (2008-2023) were analyzed. Percentiles (2.5th, 10th, 50th, 90th, 97.5th) were generated for the following hematological parameters included in the full/complete and differential blood count (FBC, CBC): leukocytes, thrombocytes, hemoglobin, hematocrit, neutrophilic granulocytes, and lymphocytes. Stringent exclusion criteria minimized confounding factors. Comparisons were made between appropriate-for-gestational age (AGA) and small-for-gestational age (SGA) neonates. A total of 3128 eligible preterm neonates with a median (minimum; maximum) gestational age of 32.1 (23.1; 34.0) weeks and a birth weight of 1700 (297; 3210) grams were included for analysis. Reference intervals were established for each parameter across gestational ages and postnatal days. Significant differences were observed between AGA and SGA neonates, particularly for leukocytes, thrombocytes, and neutrophilic granulocyte with lower values in SGA infants. Hemoglobin concentration and hematocrit were largely similar between groups, with some exceptions at specific gestational ages.Conclusion: This study provides reference intervals for hematological parameters in preterm neonates, enabling improved clinical interpretation and identification of deviations. The large sample size and strict exclusion criteria enhance the validity of these reference intervals. The observed differences between AGA and SGA neonates warrant further investigation to understand the clinical implications of fetal growth restriction on neonatal hemato-/lymphopoiesis.
