Multivariable associations of clinical variables and peak RER

Clinical variable Est. beta P-value
Age −0.0004±0.0002 0.042
Women −0.040±0.004 <2×10−16
Log(body mass index) −0.100±0.010 <2×10−16
Hypertension −0.006±0.004 0.11
Diabetes −0.020±0.007 0.003
Smoking −0.048±0.007 4×10−11

The estimated (“est.”) beta coefficient represents the change in peak RER associated with a 1-unit change for continuous variables or presence vs. absence of categorical variables.

The adjusted R2 of the model is 0.078.
