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
Background: Femoral version (FV) is an anatomic parameter that has recently received increased attention in its role in multiple hip pathologies, including femoroacetabular impingement (FAI) and cam lesion development. Purpose: To evaluate site-specific femoral version and assess the relationship with the size and location of cam deformity in cadaveric specimens. Study Design: Descriptive laboratory study. Methods: A total of 1058 cadaveric femurs were selected from a historical osteologic collection. Each femur was assessed to determine the α angle, total FV, neck-based FV, and shaft-based FV. Cam morphology was defined as an α angle >60°. Pearson correlation and multiple regression analysis were performed to determine the relationship between site-specific FV location and α angle. Results: Of the cadaveric femurs, the mean ± SD α angle was 54°± 11°. There were 354 (33%) cam deformities. The mean ± SD was 11°± 12° for total FV among all specimens, 24°± 10° for the femoral shaft version, and -13°± 19° for the femoral neck version. On multivariate analysis, sex, race, femoral neck version, and femoral shaft version were independent predictors for α angle ( Conclusion: Our study reveals an anatomic relationship between site-specific FV and cam deformity; an increase in shaft FV and neck FV predicted an increased α angle. While the observed absolute value of this relationship is small, site-specific FV remains a previously unrecognized area of interest that could help explain differences previously reported in the literature regarding the multifactorial symptomology in FAI. Clinical Relevance: FV is classically reported as one value combining the femoral neck version and torsion of the femoral shaft. In addition to the identified relationship between site-specific FV and cam deformity, this study encourages clinicians to consider both contributing anatomic components of femoral version, especially when identifying the level of deformity before corrective femoral osteotomy in patients with FAI.
