Estimated unadjusted incidence rates and relative hazards of hip fracture (with 95% confidence intervals) for treated chronic hepatitis B (CHB)-infected patients compared to uninfected persons, overall and by race/ethnicity, among the U.S. Medicaid populations of California, Florida, New York, Ohio, and Pennsylvania.

^*Persons of unknown race are included in all totals except for hazard ratios. Persons of unknown race are not displayed separately.

^†Hazard ratios of hip fracture in CHB-infected versus uninfected persons are based on propensity score-matched Cox regression analyses with further adjustment for age, sex, race, and interactions for age*race and age*sex. Persons of unknown race are not included in hazard ratios.

^‡Relative hazards of hip fracture were not determined because no fracture events occurred in this group.
