Body Mass Index as a Risk Factor for Readmission Rates in Direct Anterior Approach Total Hip Arthroplasty.
Article in Arthroplasty today, 2025. 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: Multiple studies have examined the relationship between obesity and increased risk of perioperative complications in patients undergoing total hip arthroplasty (THA). The purpose of this study was to compare the rate of perioperative complications stratified by body mass index (BMI) in patients undergoing THA through a direct anterior (DA) approach. Methods: A retrospective review at a single high-volume orthopaedic specialty hospital identified all DA THAs performed between January 2019 and August 2022. Patients were stratified by BMI into the following cohorts: underweight (BMI<18.5), normal (BMI = 18.5-25), overweight (BMI = 25-30), obese class I (BMI = 30-35), obese class II (BMI = 35-39.9), and obese class III (BMI ≥ 40). Primary outcomes collected included 30-day and 90-day readmissions, emergency department visits, intraoperative fracture, and 90-day infection requiring return to the operating room. There were 4767 patients with a mean BMI of 28 kg/m Results: Thirty-day readmission rates in the obese class III (6.2%) were significantly higher when compared individually to all other cohorts ( Conclusions: Obese class III patients have a higher rate of 30-day readmission following DA THA than all other BMI cohorts and are at increased risk of infection requiring return to the operating room when compared to patients with normal BMI. Surgeons should counsel patients regarding the increased potential complication risks related to BMI.
