Association between trochanteric fractures and gluteal muscle size, density in older women: a cross-sectional study at a university hospital.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
purposeThis study aimed to investigate differences in hip muscle area and density between older women with femoral neck fractures (FNF) and trochanteric fractures (TRF).
designCross-sectional study. SETTING AND
participantsThe study was conducted at a university hospital. A total of 554 older women patients were enrolled, comprising 314 with FNF (mean age 77.02±7.15 years) and 240 with TRF (mean age 79.70±6.91 years), for comparative analysis.
methodsCT scans were used to measure the area and density of the gluteus medius and minimus muscles (G.Med/MinM) and the gluteus maximus muscle (G.MaxM). Areal bone mineral density (aBMD) of the total hip (TH) and femoral neck (FNaBMD) were quantified using quantitative CT. The cohort was stratified by age (cut-off 80 years) to explore age-specific associations.
resultsAmong all subjects, the FNF group exhibited significantly higher muscle parameters compared with the TRF group (p<0.001). With adjustments made for age, body mass index (BMI) and THaBMD, all muscle parameters, except G.Med/MinM density, showed significant correlations with TRF. In the age ≥80 group, no statistically significant correlations were observed between hip muscle parameters and TRF. Conversely, in the age <80 group, adjusting for age, BMI and THaBMD revealed significant associations between decreased muscle density and area of both G.MaxM and G.Med/MinM with TRF.
conclusionsOur findings suggest that in older women, particularly those under 80 years of age, gluteus muscle parameters are associated with TRFs, independently of BMD.
