Sequence of events of training workshop and testing.
The workshop consisted of a knowledge test before and after a lecture on retinoblastoma genetics, small group discussions of case studies, and role-play presentations of case study scenarios. Informed consent was obtained from workshop participants who agreed to have their tests included in this analysis, and tested 1-year after the workshop.

An introduction to retinoblastoma genetics.
Retinoblastoma is initiated by loss-of-function of the tumor suppressor gene RB1 (RB1-/-) in one eye (unilateral) or both eyes (bilateral). There are different implications for care for different scenarios. Notably, a rare cause of non-heritable retinoblastoma is unrelated to RB1, amplification of the gene MYCN.

Mean test scores pre-, post- and one-year post-workshop.
Scores are patterned according to the question category. The leftmost column displays what a perfect test would look like, where “risks to individual” questions encompass 50% of the test, and “family planning” and “retinoblastoma causative genetics” are the subject of 25% of the questions each. The weighted score for each category is listed on the right of the column for pre-, post- and one-year post-workshop scores. Error bars indicate standard deviation per category.
