Comparison of biological variables, work performed, and pulse rate before and after exercise in white and African/Afro-Caribbean subjects
| Variable | Whites median (range) or mean (SD) | Africans/Afro-Caribbeans median (range) or mean (SD) | Difference in mean or median (95% CI) | p Value |
|---|---|---|---|---|
| Data are the mean or median and the 95% range (SD), except for the significance of the difference where the 95% confidence interval (CI) is given. | ||||
