We hypothesized that the time course of the Burden of Amplitudes and Epileptiform Discharges (BASED) score after ES remission is associated with ES relapse. This study aimed to investigate the association between ES relapse and BASED scores at the time of initial ES remission and during the subsequent follow\u2010up period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We collected clinical and digital EEG data at four hospitals from patients with IESS who achieved initial ES remission. The BASED score was evaluated using EEGs obtained before remission, during remission, and after remission.

We analyzed the associations between clinical factors, BASED score, maximum BASED score, and ES relapse.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Data were collected from 44 patients aged 4\u20138\u2009months at disease onset, which included 33 nonrelapsed and 11 relapsed patients.
