- CMAs 1–4 are measures of medication acquisition while CMAs 5–8 are measures of medication availability. For the latter, the subscript denotes the oversupply handling approach: Discarding all remaining medication, Retaining all remaining medication, Capping the amount of remaining medication. CMA1 and CMA2 have values in the range [0,∞), While CMAs 3 to 8 have values in the range [0,1]. For all measures, a value of 1 represents ‘perfect’ adherence. Values over 1 for CMA1 and CMA2 represent ‘excessive’ adherence, or medication oversupply. All correlation coefficients were statistically significant (p < 0.05). Colour coding key for magnitude of correlation coefficient: light orange – less than 0.3, light green – 0.3 to 0.4, medium green – 0.4 to 0.5, dark green – over 0.5
