Display of results at the disease category level.

<p>A) Phosphatidylcholine, the major surfactant phospholipid class and B) its species dipalmitoylphosphatidylcholine (PC 32:0) are given as individual results of all patients included in the study according the disease category they belong to. The statistical comparisons were done by ANOVA and Dunn’s post hoc test; all significant results are displayed in each figure. To take multiple comparisons into consideration, an overall cut-off level of P<0.0182 was calculated. For A) 1-way ANOVA gave a P = 0.0020, for B) P < 0.0038; the significant results of Dunn’s post hoc tests are indicated as following: ____ = P < 0.05, _ _ _ = P < 0.01, and …. = P < 0.001. The species of the other phosphatidylcholines, the other phospholipid classes and their species composition are displayed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117985#pone.0117985.s003" target="_blank">S3 Fig</a>.
