Table 1 Prevalance of cHSP60 and cHSP10 specific antibodies in study population

Groups	Age Median (range)	cHSP60-IgG	cHSP10-IgG
		Number (%)
Group I (n = 39)	25 (21–37)	3 (8)	2 (5)
Group II (n = 63)	27 (23–43)	15 (24)^a	13 (21)^b
Group III (n = 70)	29 (21–42)	35 (50)^c,e	26 (37)^d,f

(n) represents number of patients
^aP = 0.04 as compared to Group I; ^bP = 0.03 as compared to Group I; ^cP < 0.0001 as compared to Group I; ^dP < 0.0001 as compared to Group I; ^eP = 0.002 as compared to Group II; ^fP = 0.04 as compared to Group II where,
Group I-Healthy women with no infertility problem
Group II-Chlamydia positive women with no infertility problem
Group III-Chlamydia positive women with infertility
Categorical variables were compared using the χ² test
