Only 54-55% of these respondents claimed to consistently practice preventive measures, including wearing face masks. Almost 60% of those with diabetes experienced food or medication shortages during the quarantine period, which was much higher than those without diabetes. Importantly, respondents who experienced medication shortages reported a 63% higher COVID-19 infection rate. Diabetes was associated with an increased risk of self-reported personal and family member COVID-19 infection, which is mitigated by consistent use of face masks.Irisin, an emerging adipokine, has been involved in the pathogenesis of type 2 diabetes mellitus (T2DM). However, previous studies evaluating the association between irisin and diabetic nephropathy (DN) showed inconsistent results. We performed a meta-analysis to evaluate the above association. Matched case-control studies evaluating the difference of serum irisin between T2DM patients with and without DN were identified via systematic search of PubMed, Embase, Cochranes' Library, China National Knowledge Infrastructure, and WanFang databases from inception to December 5, 2020. A random-effects model or a fixed-effects model was used to pool the results according to the heterogeneity. Overall, thirteen matched case-control studies including 1735 T2DM patients were included. Results of meta-analysis showed that compared to T2DM patients with normoalbuminuria, those with microalbuminuria [10 studies, standard mean difference (SMD) 1.12, 95% confidence interval (CI) 0.48-1.77, p less then 0.001; I2=94%] and macroalbuminuria (10 studies, SMD 1.86, 95% CI 0.93-2.79, p less then 0.001; I2=97%) had significantly lower serum irisin. Besides, the serum level of irisin was significantly lower in T2DM patients with macroalbuminuria than those with microalbuminuria (10 studies, SMD 0.91, 95% CI 0.44-1.38, p less the
