Table 2.
Related work compiled from Beniczky et al., 2021 [4], and this study as comparison. Only those works are included that involve seizure types relevant to this study, that is, any of focal motor seizures, SPS, CPS, or other non-generalized seizures. FAR24: false alarm rate per 24 h; PPV: positive predictive value; FS: focal seizures; SPS: simple partial seizures; CPS: complex partial seizures; hyper: hypermotoric seizures; myo: myoclonic seizures; FS min mot: focal seizures with minimal motor component.

+ The study also contained other seizure types, most notably generalized seizures, however the presented data only relates to those seizure types specifically mentioned. * Performance scores only include CPS, calculated by authors from original reported numbers. § Performance scores represent a non-optimized detection, and a refined analysis, respectively.
