Bland Altman Plots for repeatability of MSL and SOREMPs for NT1 and NT2 after excluding patients taking medication(s) at time of first and/or second MSLT. MSL1 and MSL2 represent MSL on first and second MSLT, respectively. SOREMP1 and SOREMP2 represent number of SOREMPs on first and second MSLT, respectively. MSL = mean sleep latency, MSLT = Multiple Sleep Latency Test, NT1 = narcolepsy type 1, NT2 = narcolepsy type 2, SOREMP = sleep onset rapid eye movement period.
