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

Background: Pallister-Killian syndrome (PKS) is a rare disorder caused by tissue-limited mosaicism tetrasomy of chromosome 12p. Affected newborns show a typical dysmorphic pattern: macrosomia, coarse facies, hypertelorism, small nose with long philtrum, V-shaped upper lip, low set ears, frontotemporal alopecia, and patchy pigmentary skin and hair anomalies. Seizures and developmental delay, cardiac defects, diaphragmatic hernia, and renal/anal malformations may be associated. Case: Here, we report the case of a newborn with multiple congenital malformations, later diagnosed with PKS. Conclusions: Phenotypic and cytogenetic variability of PKS, together with the lack of correlation between tetrasomic cells' proportion and disease severity, may be challenging for diagnosis. Therefore, a detailed physical examination is mandatory for early clinical suspicion and to guide further investigations. The usefulness of array-CGH performed on peripheral blood should also be emphasized as a sensitive diagnostic tool.
