It is noteworthy that the trend for the number of implants was of borderline significance (S-score = 8, Sens slope estimate 8.44, Mann-Kendall statistic = 1.959, P = 0.0500) and for the number of detox's was highly significant (S-score = 19, Sens slope estimate = 14.56, Mann-Kendall statistic 2.853, P = 0.0043) as illustrated for both variables in Figure 4 .
