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

Inverted duplication syndrome with an adjacent terminal deletion of the short arm of chromosome 8-inv dup del(8p)-is a rare complex structural chromosomal rearrangement with a wide range of clinical manifestations. Molecular cytogenetic variants of chromosomal imbalance depend on the mechanism of rearrangement formation. We analyzed the clinical-genetic and molecular cytogenetic characteristics of the 8p inverted duplication/deletion syndrome, as well as the genotype-phenotype correlation in eight unrelated cases with the rearrangement of inv dup del(8p). The main clinical manifestations in all cases are psychomotor and language delay, muscle hypotonia, and dysmorphic facial features. Malformations of the central nervous system, such as corpus callosum agenesis, were found in five cases. Seizures were reported in only one case. We found that the cause of the formation of the rearrangement was generally ectopic recombination (seven out of eight cases) and this was due to U-type exchange in only one case. Depending on the mechanism of formation, the characteristics of the genomic imbalance were different, which made it possible to identify two molecular cytogenetic variants in the cases we describe here. No association between molecular cytogenetic variants and clinical manifestations was found.
