Control subjects matched to cases were recruited from general practice.</p> </sec> <sec id="joim12155-sec-0004" sec-type="section"> <title>Analysis</title> <p>Multivariate conditional logistic regression analysis; factors included age, geographical origin, smoking, alcohol consumption, use of oral contraceptive(s) or vaccine(s) other than Gardasil received within 24 months before the index date and personal/family history of ADs.</p> </sec> <sec id="joim12155-sec-0005" sec-type="section"> <title>Results</title> <p>Overall, 211 definite cases of ADs were matched to 875 controls. The adjusted odds ratio (OR) for any quadrivalent HPV vaccine use was 0.9 [95% confidence interval (CI) 0.5–1.5]. The individual ORs were 1.0 (95% CI 0.4–2.6) for ITP, 0.3 (95% CI 0.1–0.9) for MS, 0.8 (95% CI 0.3–2.4) for connective disorders and 1.2 (95% CI 0.4–3.6) for type 1 diabetes. No exposure to HPV vaccine was observed in cases with either Guillain–Barré syndrome or thyroiditis.</p> </sec> <sec id="joim12155-sec-0006" sec-type="section"> <title>Conclusions</title> <p>No evidence of an increase in the risk of the studied ADs was observable following vaccination with Gardasil within the time periods studied. There was insufficient statistical power to allow conclusions to be drawn regarding individual ADs.</p> </sec> </abstract>
