Bland Altman Plots for the 5R-STS test in adolescents and adults of both sexes with ID. Bland Altman for theanalysis of agreement between the 5R-STS. The sample is represented at each point on the graph by transmitting the average value of the two evaluations (x-axis) and the difference between the two evaluations (y-axis). The mean difference was the estimated bias, and the standard deviation (SD) of the fluctuations around this mean, outliers are considered above 1.96 and under -1.96 SD (outlier). The center line shows the mean difference between the analyzed tests and upper and lower limits of agreement of the 95% CI for the difference between means. (A): Male adolescents; (B): Female adolescents; (C): Male adults; (D): Female adults.
