Table 3. Alteration of prescription patterns after delivery in AS according to delivery method.
| Variables | Cesarean section (n = 211) | VD (n = 207) | ORa | 95% CI | aORb | 95% CI |
|---|---|---|---|---|---|---|
| Overall | 60 (28.4) | 44 (21.3) | 0.68 | 0.43–1.06 | 0.72 | 0.45–1.14 |
| Use of new corticosteroid or increase in dose | 22 (10.4) | 25 (12.1) | 1.18 | 0.64–2.17 | 1.23 | 0.66–2.31 |
| Regular use of new NSAIDs or increase in dose | 25 (11.8) | 13 (6.3) | 0.50 | 0.25–1.00 | 0.50 | 0.25–1.02 |
| Use of new DMARDs or increase in dose | 37 (17.5) | 27 (13.0) | 0.71 | 0.41–1.21 | 0.73 | 0.42–1.27 |
| Use of TNF inhibitors | 4 (1.9) | 3 (1.4) | 0.76 | 0.17–3.44 | 0.89 | 0.19–4.15 |
Data are presented as number (%).
AS = ankylosing spondylitis, VD = vaginal delivery, OR = odds ratio, aOR = adjusted odds ratio, CI = confidence interval, NSAIDs = non-steroid anti-inflammatory drugs, DMARDs = disease modifying anti-rheumatic drugs, TNF = tumor necrosis factor.
aOR of change in prescription compared between 2 groups using a generalized linear model with binomial distribution (reference group: cesarean section); bAdjusted for the presence of uveitis, inflammatory bowel disease, or psoriasis.
