Table 3.

Basic set of covariates (age groups, antidepressant/antianxiety prescription drugs) and extended set of covariates (basic + inhibitors, joint complications) associated with annual use (yes/no; OR [95% CI]) and annual volume (% difference [P value] if use > 0) of any pain medication (opioids, nonopioids, NSAIDs, and/or steroids) in years with ≥1 filled prescription for PwH compared with that for controls. Longitudinal regression analysis of annual data on the use of 7 prescription drug types and volume of 7 prescription drug types for years 2007-2017 in Sweden by subgroups such as moderate-to-high factor consumption, low factor consumption, and women including carriers.

Note: The reference person for comparison of regression estimates is a control <30 years old not using antidepressant or antianxiety prescription drugs, and without joint complications (and no inhibitors by definition).

NSAIDs, nonsteroidal anti-inflammatory drugs; OR, odds ratio; PwH, people with hemophilia.

a

Filled prescription (≥1) during the calendar year of any antidepressant or antianxiety prescription drugs.

b

Use of bypassing agent or FVIII or FIX at a dosage of ≥350 IU/kg/week in current or any previous year.

c

Orthopaedic joint surgery and/or registration of the health care contact with hemarthrosis (M25.0, M36.2). Registration of the surgery indicator in the current or past years.
