Categorical variables (e.g., gender) are represented by counts with percentages in parentheses. Age (a continuous variable) is represented by means with standard deviations in parentheses. Gender is tested with a chi-squared test; race and ethnicity are tested with Fisher’s exact test. Age is tested with a t-test.
