  1. Presented are the mean adjusted values from a mixed effects linear model. Fixed effect: mattress type, CPR backboard use, feedback source, interaction between feedback source and mattress type, and interaction between feedback source and CPR backboard use. Random effect: intercept, mattress type, CPR backboard use, and feedback source. Goodness of fit: marginal R 2 = 0.43, conventional R 2 = 0.80
