The Effect of Obesity on Prosthesis Positioning in Total Hip Arthroplasty Through the Posterolateral Approach: A Retrospective Study on 614 Total Hip Arthroplasties.
Article in Arthroplasty today, 2025. 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
Background: In total hip arthroplasty (THA), orientation of prosthesis components is important regarding outcome. Obesity has been related to poorer placement of the acetabular component. Larger studies investigating the detailed impact of body mass index (BMI) > 35 kg/m Methods: This retrospective observational study analyzed 614 THAs performed between 2015 and 2022 categorized in an obese and a normal-weight group. Cup positioning and orientation, stem alignment, and leg length discrepancy were assessed using preoperative and postoperative radiographs. Adjusted multiple linear regression models were applied to detect statistically significant differences in cup and stem orientation and placement between the 2 groups. Results: A total of 614 hips were analyzed, including 156 from patients with a BMI > 35 kg/m Conclusions: The influence of obesity on inclination and anteversion angles should be considered during THA to prevent substantial malpositioning of prosthesis components. Further research is required to determine the clinical implications of these variances in prosthesis component placement between normal-weight and obese patients, particularly given the ongoing debate regarding the optimal 'safe zone' for acetabular component positioning and orientation.
