* Nonincentivized had a higher percent of meeting Papanicolaou criterion during some early time periods: 3^rd and 4^th quarters of 2003 (P < .05 for all).
† Incentivized had a higher percent of meeting Papanicolaou criterion during some late time periods: 2^nd, 3^rd, and 4^th quarters of 2005 (P < .05 for all).
