Pressbox (Press Release) - In the patient-level meta-analysis, only the first event was included if several occurred. Statistical analyses were performed in R version 3.0.2 (R Foundation for Statistical Computing, Vienna, Austria), using the metafor package (version 1.9-2) for meta-analysis. We used standard summary statistical tests. Quantile-quantile plots identified the following continuous variables as significantly non-normal: FFR, weight, body mass index, minimal lumen diameter, and reference vessel diameter. Applicable tests were 2-tailed, and p?<0.05 was considered statistically significant. Further statistical methods can be found in the Online Appendix. SB-431542 For the study-level meta-regression, length of follow-up was heterogeneous. To adjust for the differences, 2 methods were compared. The simple method normalized each MACE rate to 12 months. For example, 10 events in 100 subjects over 8 months would yield a normalized MACE rate of [(10/100)/8]��12?= 15% at 1 year. The more complex method adjusted the normalized event?rates on the basis of a Poisson regression predicting MACE?as a continuous function of length of follow-up. Fixed and random (DerSimonian and Laird) effects meta-regressions of the incidence rate included the mean FFR value, revascularization as a binary variable, and an interaction term. The optimal outcomes-based threshold occurred at the intersection of the unrevascularized and revascularized fitted curves. Note that some intersections did not occur within the plausible FFR range Venetoclax datasheet from 0 to 1, particularly with small or parallel event rates between treatment groups. To explore the hypothesis that FFR might simply reflect demographic characteristics, classic cardiovascular risk factors, or basic angiographic features, we studied the capability of other variables to predict the measured FFR value in the patient-level data. Each variable was?studied in isolation using logistic regression (quasibinomial link function in a generalized linear model). Continuous predictors check details also were examined using correlation methods, whereas binary predictors summarized by median and interquartile range were compared using the Mann-Whitney U test. Because only quantitative percent diameter stenosis showed a clinically relevant association with FFR, the adjusted model added this single variable. Additional adjustment for the type of revascularization (e.g., bare-metal stent, drug-eluting stent, unspecified PCI, or CABG) produced similar FFR thresholds. In the subset with post-PCI measurements, we found no significant interaction between FFR and the revascularization technique. Additional adjustment for the type of revascularization did not significantly alter the prognostic value of FFR in this subset. Multiple imputation was not used due to the sizable number of missing fields for covariates with a statistically or clinically insignificant association with FFR.
