Quantitative data
Quantitative data from trial surveys and routine implementation monitoring data were used. Trial surveys captured data on sociodemographic status of 319 pregnant women enrolled in the trial; their access to and familiarity with mobile phones, smart phones, and using the internet; participation of family members in the VC; and whether an action plan was developed after the VC. Trained researchers enrolled and interviewed 316 pregnant women at median 18.5 weeks (range 7 to 29 weeks) gestation, and with 271 participants at endline (29 to 97 days after enrolment). Methods for the trial survey are described in detail elsewhere [
