Comparison of the effect of random error in raw data and derived dietary factors.

<p>For each level of error (Signal to noise ratio = (∞, …, 0.1)) the correlation (R²) between matched pairs of components from original model and model build on data plus Gaussian noise (y-axis) are matched with the correlation between the original data and the original data plus error for the most influential variable of the respective component (x-axis). The results are the average over 100 repetitions.</p

Spider plot(s) of pattern score vs. food item correlations.

<p>Upper left – <i>Vegetables/Prudent</i>, upper right – <i>Western</i>, lower left – <i>Nordic</i>, and lower right – <i>Seafood</i>. The colors refer to food item subgroups. Labels are only shown for food items with a correlation coefficient above 0.3.</p

Odds ratio and 95% CI (unadjusted and adjusted for relevant confounders: maternal age, maternal height, pre-pregnancy BMI, parity, civil status, socioeconomic status and smoking during pregnancy) for preterm birth (spontaneous and induced) for each dietary pattern.

<p>Reference level is the lowest quintile. <i>P</i>-values in parenthesis are for induced- and spontaneous preterm birth respectively.</p

Maternal characteristics vs. dietary patterns.

<p>Quintilized dietary pattern scores and single maternal characteristics are compared using cross-tabulation. These cross-tables are depicted as colored circles where the color refers to the distribution of the socio-demographic factor within the dietary pattern. Top panel shows the distribution of the individual maternal covariates.</p

The associations between maternal covariates and preterm birth.

<p>The marginal effect on preterm birth is calculated by a multivariate model with confounders/covariates and quintilized pattern scores for Western-type diet as predictor. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0093644#s3" target="_blank">Results</a> are from stratification of the cases into spontaneous and induced births respectively.</p
