Evaluation of the concordance of Framingham risk scores by Bland-Altman analysis. In the Bland-Altman graph, the differences between the scores are represented on the y-axis, while the average of the scores is plotted on the x-axis. The horizontal line at the level of the bias indicates the average difference, and the additional horizontal lines represent the upper and lower limits of agreement. These limits are calculated as the mean difference plus and minus 1.96 times the standard deviation of the differences, providing a range in which 95% of the differences are expected to fall if the two methods are equivalent. Points outside these limits suggest disagreement between the measurement methods. The adapted Framingham Risk Score (FRS) was calculated using self-reported health data: (A) FRS-SAH: Based only on self-reported hypertension (hypertension diagnosis and medication use). (B) FRS-DLP: Based only on self-reported lipid profile (dyslipidemia diagnosis and medication use). (C) FRS-SAH and DLP: Combined self-reported hypertension and lipid profile
