1. Introduction Patients with heart disease will be compared with healthy patients (control group) regarding thermographic variables, speech condition (altered or not), assessment of orofacial conditions and questions about eating behavior. Firstly, regarding the orofacial conditions questionnaire (AMIOFE), multiple linear regression models were adjusted (GOLDBERG, M.A. and CHO, H.A.) to compare the three groups: control, cyanotic heart disease and acyanotic heart disease; controlling for the variables gender and age. The models were adjusted for all questions and also for the totals by category (appearance / posture, mobility and functions) and overall total. For the 12 thermographic variables, multiple linear regression models were also adjusted to compare the three groups, controlling for age and gender. T-tests were also performed to compare the means between groups for each of the variables. Regarding food consistency, a multiple linear regression model was adjusted for the total questionnaire with explanatory variables group, age and gender. To compare the eating behavior categories, a chi-square homogeneity test (BUSSAB, Wilton, MORETTIN, P. A.) was performed to verify if the distributions of the categories are different between groups. To analyze the speech condition (altered or not), a logistic regression model (NETER, J., WASSERMAN, W., KUTNER, MH and LI, W.) was adjusted to verify whether the disease group, the Age and gender are associated with the likelihood of impaired speech. Finally, to study the associations between the different variables evaluated in the study, Pearson's linear correlations were calculated between the thermographic variables, eating behavior and the AMIOFE questionnaire totals and tests were performed to verify whether such correlations were significantly different from zero. The software used for analysis was RStudio version 3.5. 2. Analysis of the AMIOFE questionnaire In order to compare patients with acyanotic and cyanotic heart disease with patients in the control group, multiple linear regression models were adjusted for all questionnaire questions and also for totals by category and overall. In these models, gender and age were also included as explanatory variables. The intercept in all tables corresponds to the expected value of the variable for newborn boys in the control group. It is important to highlight that it was not possible to construct the model for the variables lip commissures, hard palate volume, jaw slip, food leakage, choking and uncoordinated jaw movements because these variables always presented the same value for all patients evaluated. .
