Model	B [95% CI]	β	P	R2
Model I  Logical memory	−0.336 [−0.407∼−0.265]	−0.78	0.000	0.608
Model II  Logical memory Education	−0.292 [−0.371∼−0.212] −0.900 [−1.719∼−0.080]	−0.677 −0.203	0.000 0.032	0.639
Model III  Logical memory  Education  Verbal fluency	−0.217 [−0.322∼0.111] −0.936 [−1.734∼−0.139] −0.342 [−0.670∼−0.013]	−0.503 −0.211 −0.235	0.000 0.022 0.042	0.665

CI, confidence interval; excluded variables in Model III (ExV‐Model III): age, gender, visual reproduction. In Model I, all the ExV‐Model III and logical memory were entered into stepwise regression analysis; in Model II, all the ExV‐Model III, logical memory and education were entered; in Model III, all EV‐Model III, logical memory, education and verbal fluency were entered.
