TABLE 3.

Knowledge and technique scores between T₀ and T₁; T₁ and T₂.

	Median difference	Z	p‐Value	ES(r)
Knowledge T0 and T1	2	−6.23	<0.005*	0.60
Knowledge T1 and T2	1	−3.48	0.001*	0.34
Technique T0 and T1	6.33	−6.34	<0.001*	0.62
Technique T1 and T2	−0.17	−0.77	0.44	0.07

Note: ∞ES(r): Cohen (1988) criteria of 0.1 = small effect, 0.3 = medium effect, 0.5 = large effect.

^* p‐Value is significant at 0.05.
