In addition, we evaluated IRA of epileptiform discharges (EDs) and the diagnostic significance of the electroencephalographic (EEG) abnormalities. We used EEG recordings from the European Reference Network (EpiCARE) and Standardized Computer\u2010based Organized Reporting of EEG (SCORE). Six raters independently scored EEG recordings from 30 patients. We calculated the agreement coefficient (AC) for each feature. IRA of PPR using the classification proposed by the ILAE task force was only fair (AC\u00a0=\u00a00.38). This improved to a moderate agreement by using the simplified classification (AC\u00a0=\u00a00.56; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.004). IRA of EDs was almost perfect (AC\u00a0=\u00a00.98), and IRA of scoring the diagnostic significance was moderate (AC\u00a0=\u00a00.51). Our results suggest that the simplified classification of the PPR is suitable for implementation in clinical practice.<\/jats:p>","DOI":"10.1111\/epi.16655","type":"journal-article","created":{"date-parts":[[2020,9,19]],"date-time":"2020-09-19T18:43:35Z","timestamp":1600541015000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Interrater agreement of classification of photoparoxysmal electroencephalographic response"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6035-6581","authenticated-orcid":false,"given":"S\u00e1ndor","family":"Beniczky","sequence":"first","affiliation":[{"name":"Department of Clinical Neurophysiology Danish Epilepsy Center, Dianalund and Aarhus University Hospital  Aarhus Denmark  <!--Query ID=\"q4\" Text=\"AUTHOR: Please check editing\/translation of affiliations and spell out abbreviations in English as appropriate.\"--><!--Query ID=\"q5\" Text=\"AUTHOR: Please check that authors and their affiliations are correct.\"-->"},{"name":"Department of Clinical Medicine Aarhus University  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harald","family":"Aurlien","sequence":"additional","affiliation":[{"name":"Section for Clinical Neurophysiology Department of Neurology Haukeland University Hospital  Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvana","family":"Franceschetti","sequence":"additional","affiliation":[{"name":"Neurophysiology Unit IRCCS Foundation Carlo Besta Neurological Institute  Milan Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Martins da Silva","sequence":"additional","affiliation":[{"name":"Neurophysiology Section Department of Neurosciences Hospital Santo Ant\u00f3nio CHU Porto and UMIB\/ICBAS\u2013University of Porto  Porto Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1109-7296","authenticated-orcid":false,"given":"Francesca","family":"Bisulli","sequence":"additional","affiliation":[{"name":"IRCCS Bologna Institute of Neurological Sciences  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2399-7678","authenticated-orcid":false,"given":"Carla","family":"Bentes","sequence":"additional","affiliation":[{"name":"Neurology Department Santa Maria Hospital\u2013CHULN  Lisbon Portugal"},{"name":"Faculty of Medicine University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5385-761X","authenticated-orcid":false,"given":"Laura","family":"Canafoglia","sequence":"additional","affiliation":[{"name":"Neurophysiology Unit IRCCS Foundation Carlo Besta Neurological Institute  Milan Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0148-9795","authenticated-orcid":false,"given":"Lorenzo","family":"Ferri","sequence":"additional","affiliation":[{"name":"IRCCS Bologna Institute of Neurological Sciences  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7780-6617","authenticated-orcid":false,"given":"David","family":"Kr\u00fdsl","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurophysiology Sahlgrenska University Hospital  Gothenburg Sweden"},{"name":"Institute of Neuroscience and Physiology at Sahlgrenska Academy University of Gothenburg  Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"Rita Peralta","sequence":"additional","affiliation":[{"name":"Neurology Department Santa Maria Hospital\u2013CHULN  Lisbon Portugal"},{"name":"Faculty of Medicine University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Attila","family":"R\u00e1cz","sequence":"additional","affiliation":[{"name":"Department of Epileptology University Hospital Bonn  Bonn Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
