Articles with data on ED prevalence in patients diagnosed with COPD through spirometry were searched for in the PubMed, Embase, Cochrane Library, and Virtual Health Library databases from the year of their creation until January 31, 2021. The prevalence of ED was assessed with a weighted mean of the studies. A meta-analysis was performed using the Peto fixed-effect model to evaluate the association of COPD with ED.
Fifteen studies were ultimately included. The weighted prevalence of ED was 74.6%. A meta-analysis with four studies and 519 individuals showed an association of COPD with ED (estimated weighted odds ratio 2.89, 95% CI 1.93-4.32, p<0.001), with a non-negligible degree of heterogeneity (I2 57%). In the systematic review, age, smoking, degree of obstruction, oxygen saturation, and previous health status were associated with a higher prevalence of ED.
ED is common in patients with COPD and its prevalence is higher than in the general population.
方法:在PubMed中搜索了通过肺活量测定诊断为COPD的患者ED患病率数据的文章,
结果:最终纳入了15项研究。
结论:ED在COPD患者中很常见,其患病率高于普通人群。
