Statistical analysis was performed using SPSS 20.0 for Mac (SPSS Inc., USA). Continuous parameters are expressed as mean ± standard deviation (SD) unless otherwise specified; categorical variables are presented as numbers and proportions. For continuous variables, comparisons between groups were made using one-way analysis of variance (ANOVA), with a Fisher’s LSD post-hoc test. Categorical variables were compared using the Chi-square test. Relationships between CPET parameters, angiography findings, subject demographic features, STEMI characteristics, and cardiovascular risk factors were assessed using regression analyses. A p-value <0.05 was indicative of statistical significance.

Differences on baseline characteristics between cases and controls were tested using Chi-square tests (categorical variables: indication for surgery, ASA, comorbidity, smoking, sex) or Student’s t test (continuous variables: age, BMI). If distributional assumption of normality was violated, Mann-Whitney (MW) test was used. Mean SAF was calculated. The difference of mean SAF between cases and controls was tested using Student’s t test. The distribution between mean SAF and AGE was visualized in a graph. ROC curve analysis was performed to evaluate the diagnostic value of SAF for incisional hernia formation. Statistical analysis was conducted using SPSS 20.0 for MAC. A p < 0.05 was considered to be statistically significant.

Initially, the internal consistency by Intraclass Correlation Coefficient (ICC) for quantitative variables (HRpeak.training and HRmean) and the Chronbach’s Alpha for RPE scales were tested. To verify the data distribution, the test of Shapiro-Wilk was performed, which revealed that the variables had normal distribution. In this case, the mean and standard deviation for all variables were calculated.
Paired t tests to verify the differences of variables within and between (HRmax and HRpeak.training) and between training sessions (speed, distance, HRpeak.training, HRmean, and RPE scales) were performed. The relationship between the HR and RPE scales with a self-selected and imposed load was examined using Pearson correlation. The significance was set at p < 0.05 using the statistical software SPSS 20.0 for Mac (SPSS, Inc., Chicago, IL).

Statistics with recorded clinical and laboratory data of this study were analyzed using the Statistical Program for Social Sciences (SPSS 20.0 for MAC; SPSS Inc., Chicago, IL, USA). Data were presented as follows: (i) n (%) (ii) mean ± standard deviation (SD) (iii) median (range). Categorical variables were compared by Chi-square testing or Fisher's exact testing as appropriate. Continuous variables were compared by the two-sided Student's t-test or nonparametric test as appropriate. An undetectable HBV DNA level was imputed as 0 for analysis. All statistics were calculated within 95% confidential intervals (95% CI). All reported P values were two-tailed. Statistical significance was taken as P < 0.05.

All data are presented as mean and standard deviation. A dependent t-test was applied to identify differences in all dependent variables between ARG versus PLA conditions for each analyzed period. A two-way analysis of variance with repeated measures on two factors (2 x 2; condition vs. time) was used to test differences in plasma [nitrite] between ARG and PLA. All analyses were performed using SPSS 20.0 for Mac (SPSS Inc., Chicago, IL, USA). The level of statistical significance was set at a P value ≤ 0.05.

Before the start of the study, it was calculated that the statistical power to detect a true difference of at least 1.20% points (pp) in FMD between the experimental and control period was over 80% (α = 0.05), when 43 subjects successfully completed the study. For these calculations, a within-subject variability of 2.82 pp in FMD [20 (link)] was used. As the expected drop-out rate was 10%, the aim was to recruit 48 men and women.
All data is presented as mean ± SD unless indicated otherwise. All parameters were checked for normal distributions with the Shapiro–Wilk test. Fasting measurements after 4-week of placebo or theobromine intervention were compared with the general mixed model procedure with subject as random factor, and treatment and period as fixed factors. Differences in postprandial changes after 4 weeks of placebo or theobromine interventions were also evaluated with general mixed models with subject as random factor and treatment and meal as fixed factors and a treatment × meal interaction. If this treatment × meal interaction was not significant, it was omitted from the model. Results were considered statistically significant if P ≤ 0.05. All statistical analyses were performed using SPSS 20.0 for Mac (SPSS Inc., Chicago, IL, USA).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
