^a P = NS as compared to GIII; ^b P = 0.0428 as compared to GIII; ^c P = NS as compared to GIII;^d P = 0.0378 as compared to GIII; ^e P = NS as compared to GIII; ^f P = 0.0320 as compared to GIII, ^g P = NS as compared to GIII; ^h P = 0.0378 as compared to GIII; ^{i, j, k, l, m, n, o, p} P < 0.0001 as compared to corresponding GI where, Group I (GI) comprised of healthy fertile women with no CT infection, Group II (GII) comprised of CT-positive fertile women, Group III (GIII) comprised of CT-positive women with fertility disorders.
IncB- CT Inclusion membrane protein B; IncC- CT Inclusion membrane protein C; CT- Chlamydia trachomatis; IgG- Immunoglobulin G; IgA- Immunoglobulin A; +ve- positive. All categorical variables were compared using the χ² test.
