FIG 2. Summary operating characteristics and associated 95% confidence intervals for MR markers (AND combination) relative to the occurrence of a subsequent relapse. Month denotes the number of months and MR images preceding the event. MR markers are combined across each of these time segments of months using the AND function. That is, if the MR marker is present in all of the preceding months, the marker is set to 1; if absent in any of the months, the marker is set to 0.
