Note: Values are mean ± standard deviation. Mean values between age groups were compared by one‐way ANOVA with post‐hoc LSD test. Significant differences in mean values between age groups are indicated by different superscript letters a, b and c.

Abbreviations: ANOVA, analysis of variance; LSD, least significant disfference; MPA, mean probability of adequacy; ND, not determinable because PA was less than 0.001; PA, probability of adequacy.
