Bilateral Leydig Cell Tumor in a Capuchin Monkey (Sapajus apella): Case Report.
Article in Journal of medical primatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Leydig cell tumors (LCTs) are uncommon in nonhuman primates (NHPs). A bilateral LCT was identified in a 20-year-old male capuchin monkey (Sapajus apella) maintained under human care. Ultrasonography revealed a right testicular nodule, while necropsy identified bilateral testicular masses. Histopathology confirmed bilateral LCT. This case documents bilateral LCT in S. apella, a rare finding in NHPs.
