It should be clear which statistical test is associated with each p value reported. Rarely used statistical techniques should be described. In randomized clinical trials, consider reporting separate analyses with confounding variables included. If sample sizes differ between groups when patients are randomized, reasons should be provided. Use appropriate figures.
Scatter plots are useful for illustrating important correlations between variables.
Different symbols should be used when points are stacked on top of each other. Illustrations of regression lines should be overlaid on raw data. Regression lines should not extend beyond the range of the predictor variable. Confidence intervals are more appropriate than standard errors for comparison of groups. Use appropriate tables.
