Patient histograms. The analyzed dataset contained 1116 separate nasopharyngeal swab samples from 592 female (of whom 266 COVID-19 positive and 326 COVID-19 negative) and 524 male (of whom 292 COVID-19 positive and 232 COVID-19 negative) patients with ages between 0 and 94 years (mean ± standard deviation, 32 years ± 19 years). The terms female and male refers to the biological sex. (a) Histogram describing distribution of female and male patients with different ages in analyzed dataset. (b) Histogram describing COVID-19 disease distribution of patients in female and male groups with different ages.
