Table 5.

Comparison of pass rates using final expert-derived passing scores for participants who completed the OBLS course during early and late sessions.

	Early Session (Sessions 1-4)						Late Session (Sessions 5-8)

Data are presented as number (N), mean±SD and pass rate (%)

^*p-values were not different for cognitive assessment results (p = 0.5123) and cognitive pass rates (p = 0.2353) between early and late sessions

^†p-values were significant for Megacode assessment results (p < 0.0001) and Megacode pass rates (p=0.0012) between early and late sessions
