Observational study exploring the association between sexes and perioperative morbidities after aseptic hip revision arthroplasty.
Observational study in BMC musculoskeletal disorders, 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
backgroundSex-based analyses in total hip arthroplasty have become increasingly important in understanding the nuanced outcomes and risks associated with this surgical procedure. Recent studies analyzed the complex interplay between sex-specific factors and revision rates, challenging previously held assumptions about sex disparities in hip replacement outcomes. This study examines the correlation between sex and the occurrence of perioperative morbidities after aseptic hip prosthesis revisions.
methodsData from 261 patients following aseptic revision THA (total hip arthroplasty) were collected. The occurrence of systemic and surgery-related complications during the hospitalisation and in the follow up, the units of blood transfused, and the change in Hb (hemoglobin) were investigated. Hb was collected preoperatively and at 1, 2, and 4 days postoperatively. Analyses of sex differences between different BMI and age groups for perioperative complications and transfusion rates was carried out. The Fischer Exact test and the independent t-test were mainly used for the investigations.
resultsThere were significant sex differences in the length of stay (12.10 ± 4.60 vs. 13.90 ± 5.50; p = 0.007, Cohen’s d = 0.344), the BMI in elderly patients (28.30 ± 4.9 vs. 25.80 ± 4.4; p = 0.003; d = 0.553) and occurrence of multiple surgical complications (0.12 ± 0.35 vs. 0.27 ± 0.76; p = 0.024, d = 0.243), esp. delayed wound healing (n = 0 vs. n = 7; p = 0.046, phi = 0.131). Furthermore, occurrence of anemia (n = 9 vs. n = 54; p = < .001, η2 part = 0.092), and transfusion rate in elderly patients were significantly higher (0.20 ± 0.62 vs. 1.06 ± 1.83; p = 0.001, d = 0.642). Significant sex differences were found for surgical complications in the subgroup of BMI (Body-mass-Index) under 30 kg/m2 (0.12 ± 0.373 vs. 0.31 ± .84; Cohen’s d = 0.277; p = 0.027). No sex differences were found for multiple systemic complications (0.11 ± 0.44 vs. 0.13 ± 0.42, p = 0.635).
conclusionsAlthough this study found differences in the sex subgroups in terms of age and BMI, no general sex differences between men and women could be identified. When considering perioperative and follow-up risks, sexes do not play a crucial role.
