Respective distributions of the highest organisational hierarchy levels for the deficiencies and actions associated with the cases

		Cohort 1	Cohort 2	Cohort 3
Organisational level, deficiencies	Micro	121 (90)	157 (65)	179 (73)
	Meso	13 (10)	83 (35)*	67 (27)*
	Macro	0 (0)	0 (0)	0 (0)
Organisational level, actions	Micro	115 (85)	225 (65)	206 (75)
	Meso	20 (15)	120 (35)*	70 (25)*
	Macro	0 (0)	1 (0)	0 (0)

Only the highest level for each case is noted. The data in the table comprise numbers and percentages, n (%). Cohort 1: cases reported in 2006–2007, cohort 2: cases reported in 2015 and cohort 3: cases reported in 2017–2019.

*Significantly larger proportion of cases with deficiencies or actions at the mesosystem level when compared with cohort 1, p<0.005.
