| STARR cohort | |||||
| Asthma only (n=11 101) | Atopic dermatitis only (n=23 854) | Asthma or atopic dermatitis (n=43 728) | Both asthma and atopic dermatitis (n=8773) | Non-exposed (n=70 699) | |
| Incident OA, n (%) | 1956 (17.6) | 3678 (15.4) | 6968 (15.9) | 1334 (15.2) | 6318 (8.9) |
| Person-years | 93 107 | 204 427 | 373 725 | 76 190 | 552 032 |
| IR (95% CI) | 21.0 (20.1 to 21.9) | 18.0 (17.4 to 18.6) | 18.6 (18.2 to 19.1) | 17.5 (16.6 to 18.5) | 11.4 (11.2 to 11.7) |

aOR, adjusted odds ratio (adjusted for age, sex, race/ethnicity, Charlson comorbidity score, duration of follow-up, and frequency of outpatient visits, and BMI); IR, incidence rate per 1000 person-years; OA, osteoarthritis.
