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 10-month-old mixed-breed cat was presenting a female appearance; however, a detailed examination of external genitalia revealed an enlarged clitoris with spines. The urethra opened into the vagina. Laparotomy and subsequent histopathological examination revealed that both ovaries were replaced by hypoplastic testes, with underdeveloped uteruses located caudal to them. Chromosome and genetic testing using peripheral blood revealed that the cat displayed a nearly 1:1 mosaicism of the 37,X and 38,XY chromosomes and presence of the SRY gene. Only two cases of 37,X/38,XY mosaicism have been reported in cats, both displaying a normal penis and prepuce, indicating a male phenotype. To the best of our knowledge, this is the first report of 37,X and 38,XY mosaicism manifesting as a female phenotype.
