Univariate logistic regression analysis revealed the following independent predictors of PCS development in patients with T2D: newly diagnosed T2D (p<0.001), poor glycemic control with an HbA1c above 9.2% (p<0.001), history of myocardial infarction (p=0.044) or stroke (p=0.005), treatment of T2D with insulin analogs (p=0.002), moderate-to-severe COVID-19 course (p<0.001), history of treating COVID-19 with glucocorticoids (p<0.001) and mechanical ventilation (p=0.005). The gene discussed is INS; the disease is stroke disorder.
