The most common event was feeding tube placement, and the median time to any first complication varied between disorders (Fleming\u2013Harrington weighted log\u2010rank test). The specific diagnosis correlated with maximum gross motor milestone attainment (chi\u2010square test of independence). When all disorders were stratified by maximum motor milestone attainment (not specific diagnosis), the median time to adverse events was significantly associated with function (Fleming\u2013Harrington weighted log\u2010rank test).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This cross\u2010sectional, retrospective observational study demonstrated that key medical events could be identified across institutions using EHR capture. Rates of health events and attainment of maximum motor milestones varied by specific leukodystrophy type. However, when the overall cohort was stratified by severity of motor impairment rather than individual diagnoses, the frequency of health events was associated with motor function. Our findings suggest utility for development of comprehensive care models for leukodystrophies as stratified by motor function and demonstrate the utility of integrated EHR review for real\u2010world
