aCats that completed compared with cats that had either stopped or died; bCats that completed compared with cats that stopped only (i.e. those that died were excluded); cOR: odds ratio; d95% CI: 95 % confidence interval: Reference category used in logistic regression. For an explanation of the variables used, please see Tables 1 and 2. Variables highlighted in bold qualified for inclusion in the multiple regression analysis at P < 0.1 (Table 4)
