Logistic regression showing odds ratio (OR) with 95% confidence interval (CI) for the dependent binary outcome based on the key question: “Do you find that preschool noise affects the behavior of the children?” (Q52), related to single explanatory variables (crude analysis) and with adjustment to other explanatory variables (adjusted analysis).

Odds ratio of 1 denotes equal to the reference category, an OR < 1 denotes lower than the reference category and an OR > 1 denotes a value higher than the reference category.
