Measurement properties of HUI in different countries/districts and different disease groups

	Quality of PBM and evidence
	Construct validity			Test-retest reliability			Responsiveness
Hong Kong	+	H	[54]
Singapore	+	H	[12, 47, 52]	±	Lb	[12, 47]	±	Ma	[12, 24]
Thailand	+	H	[60]	+	H	[60]	+	H	[60]

Quality of PBM: + indicates sufficient results; ± indicates inconsistent results; − indicates insufficient results

Quality of evidence: H indicates high; M indicates moderate; L indicates low; V indicates very low

Italicised font indicates that grading is based on no more than three studies
