Scatterplot of the proportion defined as sufficiently active by IPAQ vs ACC+HR (a), RPAQ vs ACC+HR (b) and EPIC-PAQ vs ACC+HR (c) by country. Overall correlation (r) between prevalence estimates revealed no relationship (r = 0,28; p= 0.47, r = 0,35; p= 0.36 and r = 0.42; p= 0.27) for IPAQ vs ACC+HR, RPAQ vs ACC+HR and EPIC-PAQ vs ACC+HR, respectively.
