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

backgroundThromboelastometry (ROTEM), as a point of care test, is an attractive tool for rapid evaluation of hemostasis. Currently, no reference ranges exist for all ROTEM assays in neonates, limiting its use in this vulnerable population. The aim of the present study was: (1) to establish reference ranges for standard extrinsically activated (EXTEM), intrinsically activated (INTEM), and fibrinogen polymerization (FIBTEM) ROTEM assays in whole blood samples of healthy term neonates; (2) to determine the impact of gender, delivery mode, and hematocrit on ROTEM parameters.

methodsEXTEM, INTEM, and FIBTEM ROTEM assays were performed simultaneously with complete blood count in 215 healthy term neonates.

resultsReference ranges (2.5th and 97.5th percentiles) were obtained for clotting time (CT), clot formation time (CFT), α-angle, clot firmness at 10 min (A10), maximum clot firmness (MCF), and lysis index at 60 min (LI60, %). Reference ranges for EXTEM were CT 38-78 s, CFT 49-148 s, A10 40-65 mm, and MCF 47-69 mm, LI60 83-98%. For INTEM, CT 134-270 s, CFT 50-142 s, A10 41-63 mm, and MCF 48-67 mm, LI60 85-97%, and finally, for FIBTEM: CT 36-85 s, A10 9-25 mm and MCF 10-26 mm, LI60 92-100%. Hematocrit values were positively correlated with CT, CFT and negatively with A10, MCF values.

conclusionThis study provides, for the first time, reference ranges for ROTEM EXTEM/INTEM/FIBTEM values simultaneously in healthy term neonates. The combined evaluation of ROTEM tests increases its diagnostic accuracy, contributing to the expansion of ROTEM use in the neonatal population.
