Statistical methods / analysis
The primary outcome, level of concern regarding possible awareness during sedation, was analysed using the Chi-square non-parametric test.
Outcomes which produced nominal or ordinal data were analysed as per the primary outcome measure. Secondary outcome measures which produced interval data were analysed using an Analysis of Co-Variance (ANCOVA) for normally distributed data, to enable adjustment for co-variates.
