A Doctor Is Undertaking a Double-Blind Randomized Controlled Experiment to See

A doctor is undertaking a double-blind randomized controlled experiment to see if a new cream might lower the likelihood of recurrence in chronic recurrent atopic dermatitis. A total of 30 patients with moderate to severe atopic dermatitis who were undergoing a flare were randomly divided into two groups: 15 received the new cream, and 15 received just emollient. After two weeks of therapy, the new cream group had a 25% recurrence rate, whereas the emollient alone group had a 50% relapse rate. The difference, however, is not statistically significant (p = 0.14) . According to the doctor, using the new cream does not lessen the likelihood of recurrence in chronic recurrent atopic dermatitis. Which of the following is most likely to explain the results of the study?

A) Ascertainment bias
B) Confounding bias
C) Ecologic fallacy
D) Insufficient statistical power
