Analysis of factors contributing to postoperative body weight change in patients with gastric cancer: based on generalized estimation equation.

abstract：:Wildlife biologists often use grid-based designs to sample animals and generate abundance estimates. Although sampling in grids is theoretically sound, in application, the method can be logistically difficult and expensive when sampling elusive species inhabiting extensive areas. These factors make it challenging to s...
