Inverse average length of segments

Diffuse-late physical activity phenotype is associated with inverse average length of segments in humans (β 0.01210, 95% CI 0.00048 to 0.02373).

“and higher IALS ({beta}: 0.01210, 95% CI: 0.00048 to 0.02373, p-value: 0.041), but not PSS or PAS, compared with the compact-early phenotype.”
