Data are presented as hazard ratios (HRs) with correspondent 95% confidence intervals (CI).

^*Fully adjusted hazard ratios included as covariates: age (as continuous); total energy intake (in Kcal, as continuous); race (white vs. others); body mass index (as continuous); education (college vs. others); smoking habits (current vs. previous/never); yearly income (≥ vs. <50,000 $); Charlson co-morbidity index; use of drugs affecting positively bone (bisphosphonates, hormones, teriparatide); calcium intake (mg/day); potassium (mg/day); vitamin D intake (mg/day); alcohol intake (% of total energy intake); physical activity scale for the elderly (as continuous).
