Relative oral corticosteroid-sparing effect of 7 inhaled corticosteroids in chronic asthma: a meta-analysis

All ICSs studied were significantly more effective than placebo for OCS sparing, but mometasone seemed to be more effective than others. However, because of very few trials for some ICSs, more placebo-controlled trials for adjusted indirect comparison or randomized trials for direct comparison of these ICSs are needed for definitive conclusions.
