Figure 2: Disposition of the ShangRing among study participants. Participants randomized to the 7-day removal group who had their ring removed as scheduled on day 7 are not shown in the graph (n = 112). The ring detached spontaneously in two participants randomized to the 7-day group before they returned for removal on day 7 (blue bars). Most participants (n = 84) randomized to the spontaneous detachment group wore the ShangRing until it fell off on its own (orange bars). The ShangRing was removed for the remaining participants (n = 32), primarily at their request (red bars).
