Table 3. Association between gross plot ratio (GPR) and daily-life gait speed (DGS) for cognitively nonimpaired (nonCI) and cognitively impaired (CI) participants.

Group	Mean DGSa (m/s)	SD DGS (m/s)	GPR-DGS,b β	GPR-DGS, R	95% CI	P value	F statistic (ANOVA)	Model R²
NonCIc	0.75	0.12	0.04	0.69	0.01 to 0.07	.03	77.13	0.48
CIc	0.73	0.08	–0.13	–0.75	–0.20 to –0.05	.01	111.39	0.56

^aDGS: daily life gait speed.

^bGPR: gross plot ratio.

^cCI: cognitive impairment.
