Chi-square automatic interaction detector decision tree analysis model: Predicting cefmetazole response in intra-abdominal infection.

Background: Cefmetazole is used as the first-line treatment for intra-abdominal infections. However, only a few studies have investigated the risk factors for cefmetazole treatment failure.

Aims: This study aimed to develop a decision tree-based predictive model to assess the effectiveness of cefmetazole in initial intra-abdominal infection treatment to improve the clinical treatment strategies.
