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

A double volume exchange transfusion (DVET) is an important, if infrequently performed, intervention to acutely lessen the total serum bilirubin (TSB) and reduce the extravascular CNS bilirubin exposure when neonatal hyperbilirubinemia poses a neurotoxicity risk. The current analysis based on the seminal works of Valaes, and Sproul and Smith, predicts that a DVET blood product of lower hematocrit (~40%) via its greater plasma volume and corresponding higher albumin content optimizes the benefits of an DVET in several ways. First, by augmenting bilirubin clearance from the extravascular space and thereby further reducing the CNS bilirubin exposure, second, by favorably positioning the intravascular albumin-bilirubin binding capacity at DVET completion to accommodate additional bilirubin equilibration and rebound hyperbilirubinemia post-exchange, and third by correcting anemia if present.
