Two-way Chi-square test to study the association between Chlamydia and HHV-6 load in cervical smear of all patients.

*Samples have been arbitrarily divided into 4 sub groups (group 1, 2, 3 and 4) depending on the HHV-6 viral load. Respective HHV-6 DNA load is mentioned within brackets.**Similarly, all the samples have been arbitrarily divided into 3 sub groups (group A, B and C) depending on the chlamydial (Ctr) DNA load. Group A: more than 25,000 copies of Ctr/1000 cells, Group B: between 100–25,000 copies/1000 cells, Group C: Below 100 copies of Ctr (not detectable)/1000 cells.
