Outcomes of primary total hip arthroplasty in patients who have a BMI less than 20.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 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
purposeLow body mass index (BMI) is an independent risk factor for morbidity and mortality, yet patients who have a BMI < 20 undergoing total hip arthroplasty (THA) have attracted little attention. This paper investigates the incidence of (1) mechanical complications (periprosthetic fracture (PPFX), aseptic loosening, and aseptic revision); (2) infectious complications (prosthetic joint infection (PJI) and surgical site infection (SSI)); and (3) venous thromboembolism (VTE) in this population up to two years postoperatively.
methodsA national all-payer database identified THA patients from 2010-2021 with low BMI (< 19.9) or normal BMI (20-24.9) (n = 25,578). Patients with trauma, malignancy, or rheumatoid arthritis were excluded. Propensity score matching yielded low BMI (n = 6372) and normal BMI (n = 14,025) groups. Chi-square analyses evaluated complication rates at 90 days, one year, and two years, with odds ratios (OR) and 95% confidence intervals (CI).
resultsAt 90 days, low BMI patients demonstrated higher rates of SSI (OR 1.64, 95% CI 1.04-2.60), PPFX (1.54, 95% CI 1.26-1.88), PJI (1.34, 95% CI 1.14-1.58), and aseptic revision (1.44, 95% CI 1.18-1.76). Elevated rates of PPFX, PJI, and aseptic revision persisted at one and two years (all P < 0.05).
conclusionPatients who had a low BMI and underwent THA demonstrated increased rates of PPFX, SSI, PJI, and aseptic revision at 90 days as well as increased rates of PPFX, PJI, and aseptic revision up to two years following surgery. Our findings suggest that patients who have a BMI < 20 may be particularly vulnerable to complications following THA.
