  • * The difference in deficit frequency by age was not significant (P = .072).

  • ** The difference in deficit frequency by age was significant (P = .001).

  • a Detected difference in deficit proportions.

  • b χ2 for associations between the deficit and administered test, corrected by a Fisher’s exact test.

  • c Significant indicators (P < .05).
