How do you identify a predictive biomarker?
Prognostic biomarkers are often identified from observational data and are regularly used to identify patients more likely to have a particular outcome.

What is the difference between prognostic factors and risk factors?
There are several other important differences between prognostic factors and risk factors: 2. Study patients are different – in prognostic studies, they have already developed the disease of interest. Risk and prognosis describe different outcomes – the onset of disease versus a range of disease consequences.
What are the conditions associated with the outcome?
Conditions associated with the outcome are identified; these are known as prognostic factors. Prognostic factors are similar to risk factors in conventional cohort studies, but they may occur at a different stage on the disease spectrum: risk factors are present before the development of a disease, whereas prognostic factors may ...
What are Laupacis and colleagues' recommendations for reviewing prognostic studies?
They suggest that readers should ask a series of questions to determine whether the results are valid, how they should be interpreted, and whether the information will benefit patients. The questions include:
Why should the study population include all those with a disease in a defined population?
Other features include: 2. To ensure an unbiased sample, the study population should include all those with a disease in a defined population, for example all those on a disease register. Patients should all be followed up from the same defined point in the disease course to ensure a precise estimate of prognosis.
What should be included in a prognosis?
Prognosis estimates should include all aspects of a disease that are important to patients, including pain and disability, not just death or recovery.
Predicting Disease Course

Predicting Treatment Response and Safety
Recent years have seen the late-phase development and approval of multiple new therapeutic compounds for the treatment of IBD. Although a growing therapeutic armamentarium can only be a positive step, success rates for individual therapies remain ∼20% to 30%.
Conclusions and Future Directions
Considerable research efforts are now being focused on developing prognostic and predictive tools that could make personalized therapy a reality in IBD ( Box 3 ). The attrition rate of promising biomarkers in oncology, however, highlights the need for appropriate methodology and careful analysis at every step of biomarker development ( Box 1 ).
Figures
Figure 1 The future of personalized therapy in IBD. Future implementation of personalized therapy in IBD is likely to require a combination of biomarkers.
How many symptoms are there in a dataset?
Note: The symptoms that are given as input to the function should be exactly the same among the 132 symptoms in the dataset.
Can machine learning predict disease?
This article aims to implement a robust machine learning model that can efficiently predict the disease of a human, based on the symptoms that he/she posses. Let us look into how we can approach this machine learning problem:
Can combined models classify all data points accurately?
We can see that our combined model has classified all the data points accurately . We have come to the final part of this whole implementation, we will be creating a function that takes symptoms separated by commas as input and outputs the predicted disease using the combined model based on the input symptoms.
