Table 3 Correlation analysis between nutritional status, muscle physical function tests (hand grip and walking tests), acute phase reaction (serum albumin), ankle brachial index and comorbidity Charlson index. All the variables are significantly correlated among them

From: Prognostic value of physical function tests: hand grip strength and six-minute walking test in elderly hospitalized patients

  1. SNS: Subjective Nutritional Score; SNS(M): Muscle component of Subjective Nutritional Score; HGS: Hand Grip Strength by dynamometry as percentage of the 50th percentile of the sample; 6MWT: distance covered at the six minute walking test; ABI: ankle brachial index; Charlson: comorbidity index (without age).
