Classification template

# Introduction to the Classification Page
- The page name should be "(Disease name) classification", with only the first letter of the title capitalized.
- Goal: To provide information on any condition-specific schema that may exist.
- This sub-category may not need its own page. If there is only a small classification schema, it can be included in the pathophysiology microchapter.
- For an example of a microchapter on classification, click here.
- As with all microchapter pages linking to the main page, at the top of the edit box put {{CMG}}, your name template, and the microchapter navigation template you created at the beginning.
- Remember to create links within Wikidoc by placing ] around key words which you want to link to other pages. Make sure you makes your links as specific as possible. For example if a sentence contained the phrase anterior spinal artery syndrome, the link should be to anterior spinal artery syndrome not anterior or artery or syndrome.  For more information on how to create links click here.
- Remember that classification is not the same as natural history of disease. For example, primary, secondary, and tertiary syphilis falls under natural history of disease, as it is the chronological progression of the same illness, whereas hepatic encephalopathy and hypoxic encephalopathy would fall under the classification of encephalopathy.
- Remember to follow the same format and capitalization of letters  as outlined in the template below.
- You should include the name of the disease in the first sentence of every subsection.

# Overview
- The overview section should include the disease name in the first sentence.
- The goal is to summarize the page in several sentences, usually stating the categories that the disease is classified by.

# Classification
- In this section you can simply list the categories that the disease can be classified under, and give a brief description of each. The disease may be able to be classified at a pathological level based on its manifestations or appearance.
- If the disease is classified under multiple categories, you may want to make a few sub-headings with the titles "Classification Based On..." For an example of a page with multiple classification schemes, click here.

# Staging of malignant diseases
- For malignant diseases with classification based on staging systems, use the template shown below when adding content to the classification page.
- Insert a table that includes the different stages and a definition of each stage. The table may be either elaborate or simple, depending on how elaborate or simple the staging system is.
- Provide proper in-text and end-of-text citation for all staging systems to avoid plagiarism.
- If a malignant disease does not have any staging system, the author should clearly mention that in the Classification page, by writing the following: There is currently no staging system for .
- Note that staging of a malignant disease it NOT synonymous with grading of the disease. Both terms should NOT be used interchangeably.
Stage: Describes the spread and extent of the disease, usually based on clinical features and findings on imaging. For example, the TNM (Tumor - Nodes - Metastasis) is a common staging system. The disease stage should be included in the "Stage" microchapter for that disease.

## Example
- According to the Ann Arbor Staging System, there are 4 stages of Hodgkin's Lymphoma based on clinical features and findings on imaging. Each stage is assigned one letter and one number that designate the number of involved lymph node regions and the presence/absence of symptoms. The stages of Hodgkin's Lymphoma are shown in the table below:
