Total cost was driven largely by implicit costs. It can thus be inferred that transport, food and drink costs were insignificant in comparison to opportunity costs of waiting and travelling times. Two anomalous values for explicit cost are not shown: 12.76 and 18.62. Values for implicit costs outside the interquartile range: 3.46, 3.74, 4.03 and 4.65. The value of zero for implicit costs reflect minimal travelling and waiting times, which was the case for a couple of patients
