Abstract

This research aimed to develop the model to predict vision threatening diabetic retinopathy (VTDR) condition in diabetic patients so that preventive medical treatments could be started at early stage for prolonging patients’ good quality of life. Two popular predicting techniques for categorical dependent variable were used in comparison. These were logistic regression and probabilistic neural network. Data for the last six months of DR patients at Nakhonpathom hospital were collected based on 18 variables from the literature. Data cleansing were implemented. Eventually, there was a total of 355 data used with 124 patients without VTDR condition and 231 patients with VTDR condition. These data were also separated into two groups.  The first group (in sample test) with 90% of the total data was used for developing the models.  The second group (out of sample test) with 10% of data was used for checking the models’ accuracy. The research results showed the overall accuracy of logistic regression model was 69.01% while the overall accuracy of probabilistic neural network model was 96.90%. Both logistic regression and probabilistic neural network models were more accurate in predicting patients with VTDR condition than without VTDR condition. The study showed significant risk factors related to VTDR condition were sex, age, cholesterol, hematocrit, creatinine, HDL-cholesterol, and body mass index.
