Abstract:Citobrush-Ayre (C+A). (Fig 1, 2, 3 ). Comparing the "cytological quality" of each spatula, significant differences were also found (p value < 0.014). The combination (C+A) and the plastic spatula had lower percentages of "less than optimal" samples (9.8% and 10%, respectively) compared with the Ayre spatula (17.3%).
