nominally significantP = 0.039
Reverse MR suggested nominally significant associations: higher genetically predicted heel BMD was associated with lower POI risk ( OR = 0.792, 95% CI : 0.635–0.988, P = 0.039), while genetic susceptibility to wrist fracture ( OR = 1.44, 95% CI : 1.038–1.986, P =0.025) and pelvic fracture ( OR =1.177, 95% CI :1.056–1.312, P =0.003) were associated with increased POI risk.
