The full cohort took a pre-test at the start of the study, before embarking on a self-paced, four-week e-learning program dedicated to learning standardized pain scales to measure discomfort in babies.

Ozawa noted that the sample size is small but also said that the improved test scores indicated the potential for e-learning.
