What is Evidence of the Rent test of the shoulder?

• There are available three studies :

• The first study is described by Wolf & Agrawal.
• Sensitivity of the Rent test = 95.7%
• Specificity of the Rent test = 96.8%
• A positive predictive value of the Rent test = 95.7%
• A negative predictive value of the Rent test = 96.8%
• Diagnostic accuracy of the Rent test = 96.3%.

• The second study is described by Cleland
• +LR of the Rent test = 32.0
• -LR of the Rent test =.04

• The third study is described by Lyons and Tomlinson
