The association between different body mass index levels and midterm surgical revascularization outcomes.

Further, BMIs of 40 kg/m 2 or higher showed a trend toward higher MACCE risks (adjusted hazard ratio, 1.32; 95% confidence interval, 0.89 to 1.95), possibly due to the small sample size.

Nonetheless, the results of the Cox regressions and survival curves remained the same ( for BMI>40 and MACCE, the significant effect turned into a near-significant effect, which we assume is because of its relatively small sample size compared to other groups).
