Authors' conclusion

Human genetic evidence suggests an association between genetically proxied GIP-GIPR pathway perturbation and lower fracture risk

Study context

Population

Main finding

As reported in the abstract

Fractures at major osteoporotic sites (GIP-GIPR perturbation, scaled to 1 kg/m² lower BMI)

Odds ratio

0.80

95% CI 0.66–0.98

GIP-GIPR perturbation
OR 0.80 (95% CI 0.66–0.98)

Further findings

Combined spine-and-hip fractures

Associations similar for combined spine-and-hip fractures under both scaling approaches (lower BMI or HbA1c), OR
0.68, 0.49-0.94 (95% CI)

Genome-wide liability to lower BMI or HbA1c

Genome-wide liability to lower BMI or HbA1c did not show the same fracture associations as GIP-GIPR perturbation

GCG-GLP1R perturbation and fractures

GCG-GLP1R estimates were imprecise

Estimated bone mineral density (eBMD)

Genetically proxied incretin pathway perturbation was not associated with eBMD

Time to fracture (Cox), per SD of GIP-GIPR genetic risk score

Fractures at major osteoporotic sites, HR
0.976, 0.959-0.992 (95% CI)
Combined spine-and-hip fractures, HR
0.971, 0.946-0.996 (95% CI)
