Subgroup analysis was further conducted on the relationship between MASLD status (A), CAP (B), LSM (C), and CDAI, respectively, according to gender, age, race, marital status, education level, PIR, BMI, as well as the presence of diabetes and hypertension. In subgroup analysis, "p for interaction" refers to the p-value used to assess whether the interaction between different subgroups is significant. By calculating the p-value for interaction, it can be determined whether there is a significant interaction between different subgroups. If p for interaction < 0.05, it can be concluded that the interaction between different subgroups is significant, meaning that these subgroups have a significant impact on the relationship between variables, and vice versa.
