Network structures of the outcomes. (a-b) Primary outcome: (a) pain freedom at 2 hours. (b) freedom from the most bothersome symptom (MBS) at 2 hours. (c-i) Secondary outcome: (c) pain relief at 2 hours. (d) sustained pain freedom from 2 to 24 hours. (e) sustained pain freedom from 2 to 48 hours. (f) sustained pain relief from 2 to 24 hours. (g) sustained pain relief from 2 to 48 hours. (h) phonophobia freedom at 2 hours. (i) photophobia freedom at 2 hours. The lines between the nodes indicate direct comparisons in different trials. The coarseness of the lines is proportional to the number of trials linked in the network
