Association between PA (measured in [1] walking, moderate and vigorous MET-min/week and [2] low vs moderate and high PA intensity) and maximal NC/C ratio

Effect estimate reflects an NC/C ratio change per IQR MET-min/week.

MET, metabolic equivalent of task; NC/C, non-compaction/compaction; PA, physical activity.
