Berry et al, 2015; Curtis et al, 2015: Data are presented as mean (SD).

*Non-normally distributed variables are presented as medians and IQRs. Normally distributed values are presented as means and 95% CIs.

BRJ, beetroot juice; DBP, diastolic blood pressure; HR, heart rate; SBP, systolic blood pressure; VO₂, oxygen comsumption.
