The aim of this dataset was to establish the reliability of anterior maximum voluntary bite force (AMVBF) in children with juvenile idiopathic arthritis (JIA) and healthy children. Children with JIA and healthy children conducted three attempts of AMVBF. The reliability of AMVBF measurement was determined by the intra-class correlation coefficient (ICC) by age, standard error of measurement (SEM), smallest detectable change (SDC), and limits of agreement (LoA).

The data are sensitive since they involve personal information of patients. There are also restrictions on use by commercial parties, and on sharing openly based on (inter)national laws and regulations and written informed consent. Therefore these data (and additional clinical data) are only available upon signing a Data Sharing Agreement (see Terms of Access) and within a specially designed environment provided by the UMC Utrecht.
