Figure 3From: Transitions into and out of daylight saving time compromise sleep and the rest-activity cyclesChanges in relative amplitude (RA), intra-daily stability (IS) and intra-daily variability (IV) in MES-subgroups/Fall. Before = mean for four days before transition, After 1&2 is mean for two days after transition, After 3&4 = is mean for the days three and four after transition.
