Correlation between immunohistochemistry and cumulative p24 endpoints. Logistic regression curves where circles represent immunohistochemistry score of 1 = positive and 0 = negative on the y-axis and cumulative p24 endpoint on the x-axis for ectocervical tissue (a) weight adjusted and (b) non-weight adjusted and vaginal tissue (c) weight adjusted and (d) non-weight adjusted. The probability of a positive immunohistochemistry result is predicted for each p24 result with a logistic regression curve shown as a black solid line where the shaded area represents the upper and lower 95% confidence limits of the curve.
