Altricial Patterns in Prenatal Skeletal Development of Two Large Neotropical Primates: The Poeppig's Woolly Monkey and the Juruá Red Howler Monkey.
Article in American journal of 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
Understanding prenatal skeletal development is essential for pregnancy monitoring and veterinary care, as well as for understanding reproductive strategies, evolutionary differences, and ecological adaptations. This study provides an ultrasonographic description of prenatal bone development in two large neotropical primates, the Poeppig's woolly monkey (Lagothrix lagothricha poeppigii, n = 24) and the Juruá howler monkey (Alouatta juara, n = 7). Bone mineralization timing and skeletal biometric data were evaluated in relation to total dorsal length (TDL), which averaged 15.7 ± 5.3 cm in the woolly monkey and 13.9 ± 7.0 cm in the howler monkey. Gestational age correlated strongly with TDL (r
