    In their article, the authors stated that 'the diagnostic accuraty of clinical signs [...] was low'. However, they do not evaluate physical signs that have been demonstrate to be useful in detecting OAD, especially Hoover's sign (the paradoxical movement of rib margin during inspiration). Hoover's sign was able to detect OAD with a sensitivity of 58% and a specificity of 86%. (Chest 2002; 122:651-5).
