3.3 Association of ED and prevalence of osteoporosis in
different subgroups
As shown in Figure 4 , the associations of ED with increased
osteoporosis were not consistently the same in subgroups analyses.
Significantly relationships of ED with osteoporosis were detected in age
≥ 45 years, obesity and those with non-diabetes population. In subgroups
analysis, no statistically significantly of interaction term between ED
and each strata factor was detected.
