An intradialytic analysis method, comprising:

• obtaining at least one input feature, wherein the at least one input feature comprises variance relation between current data and previous data of an operating parameter related to a dialysis machine and data related to a tester;
• predicting future data according to the at least one input feature through at least one prediction model, wherein the future data comprises blood pressure information and a predicted result of intradialytic hypotension at a future time point, the at least one prediction model comprises a plurality of first classification models and a plurality of second classification models, and the step of predicting the future data according to the at least one input feature through the at least one prediction model comprises:
• determining final future data according to the future data predicted by the first and second prediction models, wherein the final future data comprises the blood pressure information and the predicted result of the intradialytic hypotension at the future time point, the blood pressure information indicates systolic blood pressure, and the step of determining the final future data according to the future data predicted by the prediction models comprises:
• determining the blood pressure information in the future data predicted by the first classification models;
• and
• determining the predicted result of the intradialytic hypotension in the future data predicted by the second classification models according to the at least one input feature and the blood pressure information,
• resampling a plurality of training data used by the at least one prediction model for predicting the predicted result of the intradialytic hypotension according to the future data and corresponding actual data, comprising:
• adjusting a number of at least one positive sample and at least one negative sample in the training data according to a number ratio, wherein the number ratio is a ratio of an expected number of the at least one positive sample and the at least one negative sample, the at least one positive sample is a sample related to the intradialytic hypotension occurring in the actual data, and the at least one negative sample is a sample related to the intradialytic hypotension not occurring in the actual data;
• and
• training a new prediction model according to resampled training data.
