No difference was showed for SARS‐CoV‐2 IgM and IgG antibodies between female and female convalescent COVID‐19 patients. (A) The levels of SARS‐CoV‐2 IgM antibody in male and female convalescent COVID‐19 patients. n (male) = 109, n (female) = 429. Black horizontal dotted line represented cutoff value, 10 AU/ml. (B) The levels of SARS‐CoV‐2 IgG antibody in male and female convalescent COVID‐19 patients. n (male) = 109, n (female) = 429. Black horizontal dotted line represented cutoff value, 10 AU/ml. (C) Comparative analysis of SARS‐CoV‐2 IgM antibody level in different age groups between male and female convalescent COVID‐19 patients. (D) Comparative analysis of SARS‐CoV‐2 IgG antibody level in different age groups between male and female convalescent COVID‐19 patients. All the enrolled convalescent patients were divided into eight groups (21–25, 26–30, 31–35, 36–40, 41–45, 46–50, 51–55, and 56–66) according to age. Data are expressed as mean ± SEM and analyzed by Mann–Whitney U test. NS, No Significance, p > 0.05.
