2.5. Statistical methods

Data analysis was conducted using IBM SPSS Statistics (version 22, Chicago, IL, USA). Descriptive statistics are presented by counts and percentages for categorical variables and means and standard deviation (SD) for continuous variables. Patient demographic data from the MAMI group were contrasted against data for treated STEMI at the local referral hospital. The two groups are heterogeneous and should be viewed for presentation demographics only. Univariate analyses to identify differences in clinical characteristics were performed on data comparing two groups. The sample size was insufficient to undertake multivariate analysis. Categorical variables were analysed using a chi-square test, while continuous variables such as age were analysed via analysis of variance (ANOVA). Comparisons were performed using Bonferroni corrections and statistical significance level was set to p < 0.05.
