+A summary of the model shows that males tend to have longer delays (the posterior mean of `sexMale` is `r round(summary(fit_sex)$fixed[3, "Estimate"], 2)`) and greater delay variation (the posterior mean of `sigma_sexMale` is `r round(summary(fit_sex)$fixed[4, "Estimate"], 2)`).
+For the `sexMale` effect, the 95% credible interval is greater than zero, whereas for the `sigma_sexMale` effect the 95% credible interval includes zero.
 It is important to note that the estimates represent an average of the observed data, and individual delays between men and women vary significantly.
