Analysis
Linear mixed models were used for all analyses. For glycemic response, the independent variables condition (LGIP and HGIP) and time (22-time points) were included as fixed factors, with the following covariates included as fixed factors; sex, age, BMI, baseline glucose, and baseline DV score. Baseline glucose was the fasted baseline reading on the test day, and baseline DV score was a performance for the dependent variable being analyzed at the first session of the day. For the glycemic response analysis, baseline glucose and baseline DV represented the same data point, so this was only included once in the model. Additionally, time was specified as a repeated variable to control the covariance structure for each participant. The interaction condition∗time was specified in the model. Pairwise comparisons with Bonferroni corrections were embedded within the model. Participant identification (ID) was included as a random factor to control for the nonindependence of data within participants. The main effects of time are not reported here as these do not inform the research questions. Data from participants (
