HR (hazard ratios), aHR (adjusted HR), CI (confidence intervals)
Each of the four patterns represent individual models adjusted for the same variables: study site, race or ethnicity, symptom sensitivity score; concurrent: age, marital status, menopause status, BMI, self-reported health, physical function score, depressive symptoms, vaginal dryness, urinary incontinence; prior visit: lubricant use, importance of sex, oral sex frequency.
