Odds ratio of pet-keeping exposure and onset of wheezing at age 3 years by DLM. For comparison, the point estimates and 95% confidence intervals of the odds ratios estimated by the Multi Model are shown for the time point of the mode of each questionnaire response. The 95% confidence interval for the DLM is narrower than that for the Multi Model. The 95% confidence intervals were widened at the two ends of the figure (from approximately 15 to 18 months and from approximately 39 to 42 months) due to a lack of available data
