Spss v22.0 statistical package

Mortality and bacteremia rates are expressed as percentages and bacterial tissue concentrations (log₁₀ cfu/g) as means ±SD. The two-tailed Fisher’s test, analysis of variance (ANOVA), and the Dunnet and Tukey post hoc tests were used. A P < 0.05 was considered significant. The SPSS v22.0 statistical package was used (SPSS Inc).

Normal continuous variables were presented as mean ± standard deviation. Continuous data were analyzed by 1-way ANOVA to test for significant differences. Abnormal continuous variables were shown as median and were analyzed by the Kruskal–Wallis test. Differences in categorical variables were analyzed by Fisher's exact test. Multivariate analysis was conducted with the ordered logistic regression model reporting coefficient (Coef.). AF recurrence was analyzed in a Kaplan–Meier survival analysis. The area under the receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of the LAT. Differences were considered statistically significant at values of P < .05. Statistical analysis was performed with the SPSS v.22.0 statistical package (SPSS Inc., Chicago, IL), STATA 14 (Stata Corp, College Station, TX), and Microsoft Excel 2011 (Microsoft Corp, Redmond, WA).

A general mean ± standard error across each repeated measurement was calculated and used. The significance of the differences between the control and drought treatments were determined with two-way ANOVA and least significant difference tests (p < 0.05) using SPSS v. 22.0 statistical package (SPSS Institute Ltd., Armonk, NY, USA).
