a Linear mixed model revealed that right anterior and ventro-posterior putamen local volume showed significant interaction with time for LED increment within 24 months, which means that the larger the local volumes of structures noted above, the slower the rate of LED increment. b However, from 24 months to 48 months, the results were opposite and the large local volume of right anterior and ventro-posterior putamen correlates with a rapid increment of LED. The mapped p values are the results after multiple comparisons correction using the false discovery rate method.
