The technique requires careful weighing and analysis of the results of a large number of studies designed and carried out in different ways. The researchers divided the studies into two groups: those that were well designed (low-bias) and those they believed were not well designed (high-bias) and so not as reliable. A large proportion of the high-bias studies were financed by the supplement industry, Gluud says.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/C045EE02-2F9A-4D81-B214-06BAB40E5839/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
