significance of differences between the two clinic cohorts
2
significance of differences between the online and combined clinic cohorts.
*, **, ***
indicate statistical significance at the 0.05, 0.01, and 0.001 levels, respectively, from t-tests for continuous variables and chi square / fisher’s exact tests for categorical variables.
For continuous variables the numbers in parentheses represent standard deviations (sd). Observations with missing data (up to n=12) are excluded from the respective analyses.
