Primary Analysis
During the follow-up period, 1,142 cases of BVFL were diagnosed among
the 8,415 OSA patients. The 10,000-PYs of 139.14 in Table 2 indicates
that on an annual basis, there are around 139 patients per 10,000, which
is 1.62 times greater than OSA patients. The OSA group has a 79 percent
tendency to develop BVFL than the control group, according to the HR
value estimated using eight factors [HR: 1.79, 95 percent CI:
1.62–1.97]. In addition, individuals with a history of OP had a 35%
decreased tendency to develop BVFL [HR: 0.74, 95 percent CI:
0.65–0.85].(Figure 2)
