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
Purpose: To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods: The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the apparent neck shaft angle, true neck shaft angle, angles of version and inclination, and the Results: The time spans were ~1448 to 1573 for Alkmaar Paardenmarkt, ~1286 to 1573 for Klaaskinderkerke, and 1615 to 1866 for Middenbeemster. Femora exhibiting signs of trauma, disease, or poor preservation were excluded. There were 116 individuals (186 femora) available for study: 21 individuals (35 femora) from Alkmaar Paardenmarkt, 38 individuals (52 femora) from Klaaskinderkerke, and 57 individuals (99 femora) from Middenbeemster. There were 104 male and 68 female femora (sex not known in 14). Using an Conclusions: Cam deformities that correlate with physical activity levels were found in historical Dutch skeletal specimens. Clinical Relevance: Cam deformity is considered an adaptive response to modern athletic activity. Evaluation of historical specimens will provide a fuller understanding of this condition by revealing whether cam deformity was present in historical skeletal specimens.
