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

Reliable evaluation of testicular toxicity in nonclinical safety studies requires animals with sufficient histological testicular maturity. However, chronological age alone is an unreliable indicator of reproductive maturity in cynomolgus macaques because substantial inter-individual variation exists in pubertal development. Since histological maturity can only be confirmed after necropsy, a practical, non-invasive method for prospective animal selection is needed. This retrospective study evaluated whether in-life testicular volume could predict histological maturity suitable for routine histopathological evaluation. Testicular length and width were measured immediately before scheduled necropsy in 61 male cynomolgus macaques (
