WebThe change score model is similar to the conditional change model, but the outcome is regressed on the interval- specific starting size and the absolute differences between size at the start and end of each subsequent interval; consequently, growth in one interval may be correlated with growth in other intervals. In the change score model, each ... WebThe distribution of conditional change in BMI SDS using a two-correlation model was close to normal (mean ¼ 0.11, SD ¼ 1.02, n¼1167), with 3.2% (2.3–4.4%) of the observations below 2 SD and 2.8% (2.0–4.0%) above þ2 SD. Conclusion Conditional change in BMI SDS can be used to detect unexpected large changes in BMI SDS.
