Table 4: Multiple regression analysis of differences between SAO and ROO formulations.
CI: confidence interval, SAO: short-acting opioid, ROO: rapid-onset opioid.
R2: 0.780, p = < .0001. Each questionnaire item is evaluated at four levels (1: have no idea, 2: do not know much about, 3: well, I know, 4: know enough). The initial level "1" as the control level (baseline level), the value of each parameter represents the effect of increasing the level by one on the response.
