BMC Anesthesiology

Table 7 Studies describing relationship between handgrip strength and postoperative mortality.

AUTHOR	YEAR	Duration of mortality follow-up	Mortality "Control" handgrip strength	Control Mortality	Mortality "comparator" Handgrip strength	Comparator Mortality	Log-rank?
Cook [17]	2001	3 months	Male < 32 kg Female < 21 kg	11.3%	Male > 32 kg Female > 21 kg	2.9%	NO
Figueiredo [24]^A	2000	1 year	GS data not presented				n/a
Le Cornu [25]^B	2000	30 days, 6 months	GS < 85%	Not reported	GS > 85%	Not reported	YES*
Griffith [28]	1989	7 days	Male 27 ± 6 kg Female 13 ± 4 kg	8.7% 13.3%	Figures not presented		NO

GS = handgrip strength
A. None of the nutritional parameters assessed including handgrip strength were associated with increased risk of mortality
B. Survival plot from time of listing to transplant or death (not for grip strength)
*GS < 85% was significantly related to post transplant occurrence of major complications (definition includes death), minor sepsis and no sepsis (p = 0.05)
