Acceleration of sarcopenia in elderly patients who develop asymptomatic pneumonia shadow within one year after surgery for early gastric cancer

Table 2 Risk factors for high %SMI^†-dec^†† according to univariate and multivariate analyses

^*: The number and percentage of patients in each category in each group
^**: Variables were analyzed by a chi-squared test
^***: Variables were analyzed by a logistic regression analysis
SMI^†: skeletal muscle index = L3 skeletal muscle area (cm²)/ height (m)²
%SMI-dec^††: rate of decrease in L3 SMI = 100 x (SMI before surgery - SMI 2 years after surgery) / SMI before surgery
DG^†††: distal gastrectomy
PPG^††††: pylorus preserving gastrectomy
PG^{†††††}: proximal gastrectomy
TG^{††††††}: total gastrectomy
BMI^{†††††††}: Body Mass Index = body weight (kg)/ height (m)²
GNRI^{††††††††}: Geriatric Nutritional Risk Index = 14.89×Alb (g/dl) + 41.7×(body weight (kg)/ ideal body weight (kg))
APS^{†††††††††}: asymptomatic pneumonia shadow
