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 hypothyroid mother, due to thyroid stimulation-blocking antibody (TSBAb), gave birth three times. Although her TSBAb levels remained almost 100%, her thyrotropin receptor antibody (TRAb) levels before delivery varied as follows: 315.0, 88.2 and 34.9 IU/L in the first, second, and third pregnancies, respectively. The first baby had a hypoplastic thyroid gland and developed severe hypothyroidism three days after birth. The second and third babies only showed latent hypothyroidism. Apparent neonatal hypothyroidism due to maternal TSBAb occurs when TRAb levels are very high, and extremely high TSBAb activity might impair not only the fetal thyroid function, but also its development.
