  1. Presented are the results of linear regression models to predict the ability to recognize sepsis as an emergency. β: Unstandardized Regression Coefficients. CI: Confidence Intervals. Analyses were based on n = 740 cases and applied full information maximum likelihood information to adjust for missing values. Six regression models were estimated to disentangle the interrelatedness of different sets of predictors. Incremental R2 measures the proportion of variance in the ability to recognize sepsis as an emergency, which is explained by the predictors in models 2 to 6 in addition to the variance explained by demographics (model 1)
  2. a For frequency of health information seeking the categories “daily” and “1–3 times per week” were collapsed to the category “ > 1 × per week”
