Part I:
A total of 168 patients were enrolled, with a male-to-female ratio of
120:48 (male:female=2.5:1), the age of initiation was
0.5~85 years old, the average age was 29.8 years, and
the overall age of initiation was bimodal distribution, and the peaks of
the two age distributions were about 2~6 years old and
26~30 years old. According to whether the age of first
episode was over 18 years old, the above patients were divided into
JO-RRP patients and AO-RRP patients.There were 59 patients with JO-RRP,
the male to female ratio was 34:25, male accounted for 56.36%, female
accounted for 43.64%, and the age proportion was not statistically
significant (p=0.34). The age was 7.6±5.0 years, of which a peak
occurred at 2~6 years old, and patients in this age
group accounted for 33.4% of all JO-RRP patients. There were 109
patients with AO-RRP, the male to female ratio was 86:23, 78.9% were
males and 21.1% were females, and the age difference was statistically
significant (p<0.01). Age 41±16 years old, peak incidence in
26~30 years old.
