In the broader healthcare context it refers to any attempt to synthesise the results of more than one study on a particular topic area. We found 43 studies with 9,110 people after searching for studies up to November 2013. 1 month to 3 years. Several studies were funded by makers of chondroitin.
Chondroitin slightly slows down the narrowing of joint space on X-rays of the affected joint. We identified a lot of studies in which unsound methods were used to assess the effects of chondroitin. Data is the information collected through research. It can include written information, numbers, sounds and pictures. It is usually stored on computer, so that it can be analysed, interpreted and then communicated to others, for example in reports, graphs or diagrams. In some studies, whose methodological quality was better, chondroitin showed no improvement in pain and in physical function. Other analyses based on different methodological quality criteria reported improvement in pain and physical functionality when chondroitin was given.
What is osteoarthritis and what is chondroitin? Osteoarthritis is a disease of the joints, such as the knee or hip. When the joint loses cartilage, the bone grows to try to repair the damage, but this bone growth may make the situation worse. This can make the joint painful and unstable, which can affect physical function or ability to use the joint.
Chondroitin is an over-the-counter nutritional supplement made primarily of chondroitin sulfate. It is said to work by stopping the degradation of cartilage and restoring lost cartilage. It also contains sulfur-containing amino acids, which are essential building blocks for cartilage molecules in the human body. What happens to people with osteoarthritis who take chondroitin? An intervention that to all intents and purposes appears to be the same as that which is being assessed but which does not have the active component being assessed. People who took chondroitin rated their pain at 18 on a 0 to 100 scale. 28 on a 0 to 100 scale.
