Study protocol for the sheMATTERS study (iMproving cArdiovascular healTh in new moThERS): a randomized behavioral trial assessing the effect of a self-efficacy enhancing breastfeeding intervention on postpartum blood pressure and breastfeeding continuation in women with hypertensive disorders of pregnancy

Table 1 BP-MOM mean systolic and diastolic blood pressure at each time point in postpartum women with HDP

3-month diastolic (m, sd)	74 (8.4)	72 (8.3)	75 (8.4)	.29

6-month diastolic (m, sd)	72 (10.2)	71 (11.7)	73 (8.7)	.56
N^b	29	13	16
12-month systolic (m, sd)	118 (13)	117 (10.1)	119 (15.3)	.75

^a Data at 6-month time point does not reflect full sample size as in-person visits were limited due to the COVID-19 pandemic. ^b Blood pressure values at 12-months were derived from both home blood pressure measurements (self-reported) and in person automated office blood pressure measurements due to restrictions for in-person visits during the COVID-19 pandemic
