Medial Femoral Offset and Early Pelvic Obliquity Correction After Unilateral Total Hip Arthroplasty.
Article in Arthroplasty today, 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
Background: Pelvic obliquity (PO) may alter perceived acetabular orientation and increase the risk of component malpositioning after total hip arthroplasty (THA). Femoral offset reconstruction influences pelvic mechanics during gait; however, the effect of intraoperative offset adjustment on postoperative PO remains unclear. Methods: This cross-sectional study analyzed data from a prospective arthroplasty registry including adult patients who underwent unilateral cementless THA between 2018 and 2023 and had preoperative PO. Forty-six patients (mean age 66.8 ± 8.2 years) were included. Medial offset (MO), vertical offset, PO angle, and spinopelvic parameters were measured on standardized radiographs obtained preoperatively and at 6 months postoperatively. Patients were categorized based on postoperative improvement in PO. Functional outcomes were assessed using the Harris Hip Score and Western Ontario and McMaster Universities Osteoarthritis Index. Statistical analyses included correlation testing, chi-square analysis, and logistic regression. Results: Mean PO significantly improved from 3.4° preoperatively to 1.6° postoperatively ( Conclusions: Medial offset adjustment based on the direction of preoperative PO contributes to restoration of coronal pelvic balance and improved function after THA.
