Points	BMI	Uterine size (cm)	Abdominal surgeries	Vaginal parity	Cardiopulmonary reserve
0	≤30	≤10	None	Prior vaginal birth(s)	No significant medical co-morbidities
1	31–44	11–13	LTC/S only and/or LSC	No prior vaginal births	Mild-to-moderate medical co-morbidities (eg, mild hypertension)
2	≥45	>13	Midlline vertical or other exploratory	C/S only	Significant co-morbities (eg, history of cardiac arrest, severe hypertension, aortic stenosis, pulmonary fibrosis, etc)

BMI, body mass index; C/S, cesarean section; LSC, laparoscopy; LTC/S, low transverse cesarean section, The T score (Tewari score) is calculated by adding the points for the five components listed in the table.
