Seizure control in each trimesters between WWE with and without ASMs change by seizure types. a The occurrence and numbers of FBTCS seizures are compared between the two groups (with or without ASMs change) in each trimester of WWE b The occurrence and numbers of FIAS seizures are compared between the two groups (with or without ASMs change) in each trimester of WWE. Abrrevations: Tr: trimester; FBTCS: focal to bilateral tonic-clonic seizure; FIAS: focal impaired awareness seizure. The number of seizures was expressed as mean and the comparisons between the two groups were performed using the Wilcoxon rank sum test, as the data were not normally distributed. χ² test or Fisher's exact test was performed to compare the seizure-freedom rate. For number of seizures : *P < 0.05, **P < 0.01 and ***P < 0.001; For seizure frequency rate: ^#P < 0.05, ^##P < 0.01
