Question

Researchers investigate the effect of two drugs on patient reported quality of life (higher scores indicate higher quality.) Participants were randomized to receive one of the two drugs or a placebo. They also controlled for baseline quality of life before initiation of treatment. The ANOVA tab e for the above analyses is given below. The mean in the placebo group is the given reference for comparisons (so Treatment A and Treatment B ate dummy variables). Based on the table what can you conclude about the reported quality of life for the two new drugs?

Explanation / Answer

Treatment A has significant impact on quality of life as F(1,75)=9.72,p=0.0026<0..05

Treatment B has significant impact on quality of life as F(1,75)=9.55,p=0.0028<0..05

Baseline has significant impact on quality of life as F(1,75)=27.37,p<0.001<0..05
