Nomogram for predicting early complications after distal gastrectomy

Figure 1 Establishment of the nomogram prediction model. ¹Impact of this risk factor on complications. ²Impact of this risk factor on complications. According to the size of the "OR value" in Table 3 (Multivariate analysis of early postoperative complications in patients with distl gas cancer), the larger the OR value, the greater the possibility of complications caused by the risk factor.
