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

The BABYHUG study is the first randomized controlled prospective trial of hydroxycarbamide in infants with sickle cell anemia to look at its effect on organ function. Almost 200 patients were recruited, irrespective of disease severity, over a 3-year period and followed for 2 years. The primary end points of splenic function and glomerular filtration rate were not reached. The trial did show a benefit in frequency of pain, dactylitis, acute chest syndrome, hospital admissions and transfusion requirements. Adverse effects were low.
