A Risk Prediction Model (CMC-AKIX) for Postoperative Acute Kidney Injury Using Machine Learning: Algorithm Development and Validation

A Risk Prediction Model (CMC-AKIX) for Postoperative Acute Kidney Injury Using Machine Learning: Algorithm Development and Validation

Categorical data were presented as percentages, and a comparison between the two groups was performed using the chi-square test or Fisher exact test. To determine the risk factors for AKI, we used the logistic regression model. Multivariable analysis using logistic regression was performed on variables with a P value A total of 439,072 surgery cases from seven academic hospitals of the Catholic University of Korea were included in the study (Figure 1).

Ability of ChatGPT to Replace Doctors in Patient Education: Cross-Sectional Comparative Analysis of Inflammatory Bowel Disease

Ability of ChatGPT to Replace Doctors in Patient Education: Cross-Sectional Comparative Analysis of Inflammatory Bowel Disease

We conducted descriptive analysis and assessed evaluators’ preference ratios for Chat GPT using a chi-square goodness-of-fit test. A 2-tailed Welch t test was used to compare the mean values of the 2 responses. We defined a threshold score of 3 (acceptable) and calculated the proportion exceeding or falling below this threshold score (3), comparing them using prevalence ratios.
