| The 2.5th and 97.5th percentiles of the resulting distributions served as the upper and lower bounds of the confidence limit. |
| Comparison of population percentiles requires an adequate amount of data for statistical significance. |
| Bars above histograms indicate the 1st, 5th, 95th, and 99th percentiles of the cumulative frequency distribution. |
| 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 terms tercile, quartile, quintile and decile should refer to the percentiles which divide the distribution into 3, 4, 5, or 10 equal parts, respectively. |
