title: Association between psoriasis and chronic obstructive pulmonary disease: A systematic review and meta-analysis.
abstract: Psoriasis has been linked to an increased risk of several co-morbidities. However, its association with chronic obstructive pulmonary disease (COPD) remains unclear. To further characterize this relationship, we conducted a systematic review and meta-analysis of case-control and cross-sectional studies that compared the risk of COPD in patients with psoriasis versus non-psoriasis participants. Generic inverse variance method of DerSimonian and Laird was used to combine all the point estimates. Out of 502 potentially relevant articles, seven studies met our inclusion criteria and were included in the data analysis. The pooled odds ratio of COPD in patients with psoriasis versus control was 1.45 (95% CI, 1.21-1.73). The statistical heterogeneity was high with an I(2) of 91%. Therefore, our study provided evidence to support the increased risk of COPD among patients with psoriasis.
