PVD can be categorized using the Fontaine or Rutherford classification system. Each system grades PVD from no symptoms to major tissue loss and can be used at diagnosis and to evaluate the progression or improvement of symptoms.

NYHA and Modified Ross Heart Failure Classification for Children
The Ross Heart Failure Classification was developed to provide a global assessment of heart failure severity in infants, and has subsequently been modified to apply to all pediatric ages. The modified Ross Classification incorporates feeding difficulties, growth problems, and symptoms of exercise intolerance into a numeric score comparable with the NYHA classification for adults.
WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues
The World Health Organization classification of lymphoid neoplasms updated in 2008 represents a worldwide consensus on the diagnosis of these tumors and is based on the recognition of distinct diseases, using a multidisciplinary approach.
Classifications of Acute Kidney Injury and Chronic Kidney Disease
Recently developed consensus functional definitions on the basis of specific changes in the serum creatinine concentration and urine volume now complement anatomical approaches to diagnosis.
Definitions and Classification of Office Blood Pressure Levels (2013 ESH/ESC)
The recommended classification is unchanged from the 2003 and 2007 ESH/ESC guidelines. Hypertension is defined as values >/=140 mmHg systolic blood pressure (SBP) and/or >/=90 mmHg diastolic blood pressure (DBP), based on the evidence from randomized controlled trials (RCTs) that in patients with these blood pressure (BP) values treatment-induced BP reductions are beneficial.
Classification and Clinico-Pathological Characteristics of Different Cryoglobulinemias
Cryoglobulinemia is usually classified into three subgroups according to Ig composition: type I cryoglobulinemia is composed of only one isotype or subclass of immunoglobulin. Both type II and type III mixed cryoglobulins are immune complexes composed of polyclonal IgGs, the autoantigens, and mono- or polyclonal IgMs, respectively; the IgMs are the corresponding autoantibodies with rheumatoid factor (RF) activity.
Modified Marsh Classification of Histologic Findings in Celiac Disease (Oberhuber)
Celiac disease is a systemic immune-mediated disorder triggered by dietary gluten in genetically susceptible persons. Gluten is a protein complex found in wheat, rye, and barley. Celiac disease is characterized by a broad range of clinical presentations, a specific serum autoantibody response, and variable damage to the small intestinal mucosa.
Classification of Retinopathy of Prematurity (RP)
Retinopathy of prematurity is a vision-threatening disease associated with abnormal retinal vascular development that occurs only in premature infants.
ILAR Classification Criteria for Juvenile Idiopathic Arthritis (JIA)
Juvenile idiopathic arthritis is a heterogeneous group of diseases characterised by arthritis of unknown origin with onset before age of 16 years.
ASA Physical Status Classification
The purpose of the grading system is simply to assess the degree of a patient’s “sickness” or “physical state” prior to selecting the anesthetic or prior to performing surgery.
