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.
WQHD: 'Wide Quad HD'. A screen with such high resolution will make photos look incredible, text super-sharp, but it also gives you more workspace. WQHD stands for 'Wide Quad HD', which is also referred to QHD. The term Quad HD implies it's four times the resolution of HD, or 1280x720. We will keep referring to it as WQHD, to keep things simple (you also have qHD, or quarter HD, or 960x540).
