Absolute (L·min⁻¹) and body-mass normalized (BMN) (ml·kg⁻¹·min⁻¹) VO_2peak values, peak power output (Watt) as well as information on the methodological quality for each of the studies included per mode comparison. The level of evidence for each mode comparison, which is based on the quality of the included studies, is provided in the last column in the row highlighted in gray. Data are presented as means ± SD.

VO_2peak, Peak oxygen uptake; BMN, body-mass normalized; ACE, arm crank ergometry; WERG, wheelchair ergometry; WTR, wheelchair treadmill; UBP, upper-body poling; ns, not specified.
