Different effects of hypertension and CHD in male and female patients with COVID-19.

A. The proportions of critical disease in male and female patients with or without hypertension in different age groups were shown. B. The probabilities of developing into critical or severe/critical disease were predicted using logistic regression models containing age, gender, hypertension, and the interaction term of gender and hypertension. Age-adjusted P values for hypertension in different genders were shown. C. The probabilities of developing into critical or severe/critical disease were predicted using logistic regression models containing age, gender, CHD, and the interaction term of gender and CHD. Age-adjusted P values for CHD in different genders were shown. COVID-19=coronavirus disease 2019. CHD=coronary heart disease.
