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

Understanding of relationship between physiological condition and testicular function in captive cheetahs would be beneficial for their successful breeding and conservation. This study investigated the states of germ cells and Sertoli cells in three captive cheetahs with different ages and health conditions using histological methods. The disarrangement of Sertoli cells and germ cells in seminiferous tubules was shown in all individuals. Many Sertoli cells detached from the basal membrane suggesting the decreased blood testis barrier. Spermatogenesis was observed in two cheetahs, whereas the number of elongated spermatids was lower than in domestic cats. One old cheetah with long-term health problem had no spermatids. These findings would be useful basic information for improving the reproduction of cheetahs in zoos.
