The subgroup analysis showed that the rate of CIN was lower in the moderate ( 6/29 ; 20.7 % vs. 13/30 ; 43.3 % , p < 0.10 ) and significantly lower in both the high ( 5/21 ; 23.8 % vs. 10/18 ; 55.6 % , p < 0.05 ) and very high score groups ( 3/12 ; 25.0 % vs. 8/12 ; 66.7 % , p < 0.05 ) among the RH patients compared to the controls .
