Their willingness to proceed through the process was used to estimate the prevalence of fear. Thirty\u2010seven children (53%; 95% confidence interval [41%, 65%]) completed the approach sequence. Although the correlation of child age in months (Mean (<jats:italic>M<\/jats:italic>) = 60.1, standard deviation = 16.5, <jats:italic>N<\/jats:italic> = 70) and highest successful step (<jats:italic>M<\/jats:italic> = 5.8, standard deviation = 2.6, 95% confidence interval [5.2, 6.4]) completed was not statistically significant at the 0.05 level, <jats:italic>r<\/jats:italic> (68) = 0.21, <jats:italic>P<\/jats:italic> = 0.08, 95% confidence interval [\u22120.03, 0.42], the proportion of children aged 6\u20107 years who successfully completed all steps (14 of 21, 67%, 95% confidence interval [50%, 84%]) was significantly different from the proportion of children aged 2\u20103 years who completed all steps (six of 23, 26%, 95% confidence interval [11%, 41%]) (Fisher's exact test, two\u2010tailed <jats:italic>P<\/jats:italic> = 0.0148). A failure rate of at least 50% should be included into group size calculations when performing studies with young children (2\u20107 years), in addition to motion and other experimental factors.
