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

This study presents the first incidence of intersex associated with testis-ova in spotted scat (Scatophagus argus) reared in a controlled environment. The testis-ova is associated with the abnormal occurrence of primary oocytes (POs) in some male testis and is referred to as ectopic primary oocytes (Ecto-PO), whiles individuals with Ecto-PO are called "Ecto-PO gonad/individuals." We investigated gonads of 129 male spotted scat aged 4-12 and 18 months after hatch (mah) by histological studies for the presence of female sexual characteristics. A total of 20 out of 88 gonads representing 22.7% of male fish aged 6-12, or 15.5% of all male fish sampled, were found to have visible Ecto-PO. At least, the Ecto-PO had an average of 7 oocytes per gonadal section, indicating high severity. The Ecto-PO appears after sex differentiation and degenerates during sexual maturation. The Ecto-PO did not significantly influence the expression pattern of male and female sex-related genes performed using qPCR. Immunofluorescence of 42sp50 specifically stained the Ecto-PO without influence from the surrounding testicular tissues. In addition, temperature did not correlate with the proliferation of the Ecto-PO, but rather gonad developmental strategy. The results show that the naturally occurring Ecto-PO might not be detrimental to testis development and could be considered a frequent-high-level incidence of natural aberration. This study highlights the intricacy of fish sex differentiation and provides a new research chapter to ascertain the mystery behind the occurrence of Ecto-PO.
