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 recurrent de novo germline variant in the MAX gene, p.(Arg60Gln), has recently been associated with polydactyly-macrocephaly syndrome in six unrelated individuals. Affected individuals presented with progressive macrocephaly, post-axial polydactyly, developmental delay, autistic features and a series of craniofacial, brain, cardiac, ocular, and renal anomalies. Here, we describe two unrelated female probands with the known recurrent MAX variant, c.179G>A p.(Arg60Gln), who presented with the emerging phenotypes of the MAX-associated syndrome. We also propose that genitourinary abnormalities, including Mayer-Rokitanski-Kuster-Hauser syndrome in one individual, may constitute an expansion of the known phenotype. These findings contribute to the current knowledge regarding the phenotypic spectrum of MAX-associated polydactyly-macrocephaly syndrome.
