covariates. b Model 2: additionally included age, sex,
education, annual incomes, education, passive smoking, physical
activity, cause of infertility, living children, and infertility
treatment time. c Model 3: additionally included
frequency of insomnia, nocturnal wake frequency, daytime napping, social

was performed by assigning medians to three categories as a continuous
variable in the models.
