| The thought disturbance and anergia symptom clusters corresponded to the 80th and 25th percentiles, respectively. |
| Table 1, which contains the simulation results, therefore displays percentiles of this distribution. |
| The terms tercile, quartile, quintile and decile should refer to the percentiles which divide the distribution into 3, 4, 5, or 10 equal parts, respectively. |
| This is refected in the similar values across the percentiles of exposure. |
| When the variable being modeled is log-transformed, percentiles curves on the original scale are obtained by applying antilogs to the calculated curves. |
| The 2.5th and 97.5th percentiles of the resulting distributions served as the upper and lower bounds of the confidence limit. |
