On the basis of preliminary test data, a 4 ng/mL concentration difference and 3 ng/mL SD for MMP12 between STEMI and control patients was hypothesized. Considering equal number of cases and control and 80% power, the sample size was 9 patients per group. Considering a possible 10% drop-out rate, a sample size of 20 patients per group was estimated to be required. Results are expressed as means ± SEM. Skewness data were analyzed by the Kruskal–Wallis nonparametric test followed by the Mann–Whitney test pairwise comparison. Normality data were analyzed by 1-way ANOVA. In select cases, data were analyzed using the χ² test. The correlation between different parameters was assessed by Spearman test. A P-value of .05 was considered statistically significant. For these analyses, SPSS v.13 (SPSS, Inc., Chicago, IL) was used. All analyses were performed using Origin 9.0 for Windows software (OriginLab Corporation, Northampton, UK, www.originlab.com).

The statistical package SPSS 19.0 for Windows (SPSS Inc., Chicago, IL, USA) was used for all data analyses. Duncan’s new multiple range method was used to determine if differences from multiple comparisons were significant. One-way analysis of variance was used to compare mortality rates, pupation rates in the feeding experiments, and protein content in leaves. Origin 9.0 for Windows (Origin Lab Corp., Northampton, MA, USA) was used to create the graphs.
