Table 1 Results of the factors used in matching during Randomization and presented by intervention arm

From: The PRogram In Support of Moms (PRISM): study protocol for a cluster randomized controlled trial of two active interventions addressing perinatal depression in obstetric settings

Prevalence Depression 23.1 (6.66) 20.01 (5.92) 3.08 0.61
Prevalence Public Insurance 48.76 (32.16) 57.95 (36.4) −9.18 0.68
Prevalence Non-White 36.38 (16.95) 42.51 (23.75) −6.14 0.69
Practice Readiness Index 7.07 (1.99) 8.27 (0.82) −1.20 0.25
  1. Table 1 represents the results of the reweighted Mahalanbois Distance/Covariate Adaptive matching procedure. Matching was done on the five factors deemed most relevant a priori to matching procedures. Factors are reported as mean (standard deviation) by intervention arms in addition to differences and associated p-values. Intervention arms were the PRogram In Support of Moms (PRISM) versus Massachusetts Child Psychiatry Access Program (MCPAP) for Moms interventions. *Mean Edinburgh Postnatal Depression Scale (EPDS) score among those with an EPDS ≥10. The Practice Readiness Index (PRI) was a cumulative score (total possible 16 points) derived from the multi-component Practice Readiness to Evaluate and address Perinatal Depression (PREPD) scale.
