Endometrial Collagen in Woolly Monkey (Lagothrix l. poeppiggi) and the Uakari (Cacajao calvus).
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. Cited by 1 paper.
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
introductionThis study microscopically characterizes collagen changes and their relationship with endometrial architecture in two Neotropical primates.
methodsUterine fragments from six Lagothrix l. poeppigii and six Cacajao calvus in different reproductive phases were histologically processed using Picrosirius Red staining.
resultsIn the functional layer, collagen was highest in the early proliferative phase (5.19% ± 2.53%; p < 0.001), whereas the basal layer had the lowest percentage (5.85% ± 4.69%; p < 0.01). Type I collagen predominated, while type III was less expressed. Type I collagen varied significantly between proliferative phases (p < 0.001). The basal layer exhibited more fibers in the secretory phase (14.03% ± 8.50%; p < 0.001). Type III collagen peaked in the functional layer (0.41% ± 0.17%; p < 0.001) and basal layer (0.69% ± 0.46%; p < 0.05).
conclusionPicrosirius Red staining with polarized light effectively highlights collagen organization, aiding reproductive phase characterization in Neotropical primates.
