The grade of the histological or cytological abnormality at original presentation, the presence of a positive or negative smear or biopsy (in the interim period), and the grade of disease (if any) in the hysterectomy specimens of 71 patients who had hysterectomies after a previous cervical abnormality

	Original diagnosis: high grade disease
	CIN II/III: interim diagnosis			Moderate/severe dyskaryosis: interim diagnosis
Final diagnosis	Positive	Negative	None	Positive	Negative	None
Carcinoma	2	0	4	1	0	1
CIN II/III	3	0	6	2	0	0
CIN I	1	0	0	0	0	1
Nil	6	7	8	0	1	1

Original diagnosis: low grade disease
	BCAUS/CIN I: interim diagnosis			BNC/mild dyskaryosis: interim diagnosis
Final diagnosis	Positive	Negative	None	Positive	Negative	None
Original diagnosis refers to the grade of lesion for which the patient originally came to medical treatment.
Interim diagnosis refers to the presence (positive) or absence (negative) of an abnormal smear or biopsy between the original diagnosis and hysterectomy.
Final diagnosis refers to the presence and grade of abnormality in the hysterectomy specimen.
BCAUS, basal cell abnormality of uncertain significance; BNC, borderline nuclear change; CIN, cervical intraepithelial neoplasia.
CIN II/III	0	0	1	0	0	1
CIN I	1	0	0	0	0	2
