↵aIn Berger et al,49 4 patients received placebo, 3 received low-dose warfarin, and 1 was excluded for noncomplianace. The outcome was extent of calcinosis based on clinical and radiographic examination.
↵bIn Aggarwal et al,56 the primary endpoint was the cutaneous lesions (skin rashes) and not the calcinosis.
↵cIontophoresis was followed by ultrasound at 1.5 W/cm2 for 8 min occurring 9 times over a 3-week period. Bid: twice daily; CR: case report; CS: case series; CTD: connective tissue diseases; DM: dermatomyositis; IV: intravenous; JDM: juvenile dermatomyositis; NA: not applicable; P: prospective case series; PCT: placebo-controlled trial; R: retrospective case series; RCT: randomized controlled trial; SSc: systemic sclerosis; tid: three times daily.
