A similar analysis of the rates of ACR Pedi 30 responses did not show significant differences for either treatment (leflunomide group, 79 percent at both 16 and 48 weeks; P=1.00; methotrexate group, 91 percent at both 16 and 48 weeks; P=1.00).
qw stands for 'Quote word'. It usually used to create array. Ex. @arr = qw/one two three/; This will create an array with elements one, two and three. Instead of '/' symbol, any other symbol can be used. Ex. @arr = qw #one two three#; @arr = qw %one two three%; If using brackets as symbol, we have the option to use open and closing braces on either end. Ex. @arr = qw [one two three]; or, @arr = qw{one two three}; or, @arr = qw (one two three); Note: Each space considered as seperator for new element.
Edit. The hack allows you to run unsigned code also known as homebrew. Homebrew code allows the Xbox 360 console to do extended features outside what was planned by the manufacturer (Microsoft).dit. This is a new hack which can boot homebrew code in less than 5 seconds. For now, all we need to know is that this is a new way to exploit the well-known 4532 kernel, in a way which also works on updated machines, unless they have been updated by the summer '09 update. It also works on all hardware types.
