  • Data are presented as n (%) or median (interquartile range). Among women ever sexually active, data are missing from one woman for age and PHQ-9, from two women for years on dialysis and the SF-12 composites; and from three women for iPTH. For women never sexually active, data are missing from one woman for marital status, albumin, and the SF-12 composites, from two women for overall sexual satisfaction, and from six women for iPTH. MWF, Monday Wednesday Friday; CCI, Charlson Comorbidity Index; iPTH, intact parathyroid hormone; SF-12, Short Form 12; PHQ-9, Patient Health Questionnaire 9.

  • a Ever sexually active or never sexually active denotes sexual activity during the study period.

  • b Data reflect baseline values.
