Results of the analysis of MACE rates. (Left): forest plot presenting the analysis of major adverse cardiovascular event (MACE) rate for the two groups treated with rotational atherectomy combined with either modified balloon types (RA + MB) or with plain balloon angioplasty (RA + BA). (Right): results of the risk of bias and certainty of evidence assessment. Green indicates low risk, yellow indicates moderate risk, and red indicates serious risk of bias. BA = plain balloon angioplasty; MB = modified balloon; RA = rotational atherectomy [13,16,30,31,32,33,34,35,36].
