| Nasal lavage parameters were distributed log-normally, and, therefore, were log-transformed before analysis. |
|
| The shape of the distributions approximates a normal distribution and indicates that fractional expression costs are log-normally distributed. |
|
| The physiologic measurements and cytokine concentrations were log-normally distributed, whereas the other microbial variables were highly skewed. |
|
| Consequently, distribution parameters were estimated on the basis of the upper tail of the distribution, with the assumption that all data were log-normally distributed. |
|
| Because measurements of nonspecific airway responsiveness are log-normally distributed in the population, an arbitrary cutoff has been selected in defining an abnormal test. |
