Measure of Performance Years of Follow-up Probability of Death*
Summary score 1 1/1+e−[−6.36 + 0.05(age) − 0.96(sex) − 0.09(SS)]
Summary score 4 1/1+e−[−4.33 + 0.06(age) − 1.12(sex) − 0.16(SS)]
Gait speed 1 1/1+e−[−6.40 + 0.05(age) − 0.96(sex) − 1.16(GS)]
Gait speed 4 1/1+e−[−4.98 + 0.06(age) − 1.09(sex) − 1.60(GS)]

Sex = 0 for men, 1 for women; SS = summary performance score, GS = gait speed (m/s). All coefficients are significant at p < .05 in all models.
