Criteria in our modified version compared to the original Fried phenotype model

Component	Modified version	Original Fried version
Exhaustion	Feeling constantly fatigued for more than one week before the stroke	Everything was an effort ≥3 days the last week
Low physical activity	Engaging in exercise/ physical activities less than once a week before the stroke	Kilocalories expended per week – lowest quintilea
Weight loss	Unintentional weight loss of ≥3.0 kg the last 6 months before the stroke	Unintentional loss of ≥4.5 kg OR ≥ 5% of body weight the last year
Slow gait speed- Gait test, 4 m	Duration ≥6 s OR not able	Duration ≥6 s (women ≥ 159 cm; men > 173 cm) Duration ≥7 s (women < 159 cm; men < 173 cm)
Weak grip strength – Jamar® dynamometer	Best measure on strongest hand, using value-sets by Fried et al.b OR not able	Best measure on dominant hand, using value-sets by Fried et al.b
