The weight-increasing effect of fructose in hypercaloric trials may have been attributable to excess energy rather than fructose itself .
Fructose does not seem to cause weight gain when it is substituted for other carbohydrates in diets providing similar calories .
Free fructose at high doses that provided excess calories modestly increased body weight , an effect that may be due to the extra calories rather than the fructose .
BACKGROUND The contribution of fructose consumption in Western diets to overweight and obesity in population s remains uncertain .
PURPOSE To review the effects of fructose on body weight in controlled feeding trials .
Extending the CONSORT statement to randomized trials of nonpharmacologic treatment: explanation and elaboration.
Adequate reporting of r and omized , controlled trials ( RCTs ) is necessary to allow accurate critical appraisal of the validity and applicability of the results . The CONSORT ( Consoli date d St and ards of Reporting Trials ) Statement , a 22-item checklist and flow diagram , is intended to address this problem by improving the reporting of RCTs . However , some specific issues that apply to trials of nonpharmacologic treatments ( for example , surgery , technical interventions , devices , rehabilitation , psychotherapy , and behavioral intervention ) are not specifically addressed in the CONSORT Statement . Furthermore , considerable evidence suggests that the reporting of nonpharmacologic trials still needs improvement . Therefore , the CONSORT group developed an extension of the CONSORT Statement for trials assessing nonpharmacologic treatments . A consensus meeting of 33 experts was organized in Paris , France , in February 2006 , to develop an extension of the CONSORT Statement for trials of nonpharmacologic treatments . The participants extended 11 items from the CONSORT Statement , added 1 item , and developed a modified flow diagram . To allow adequate underst and ing and implementation of the CONSORT extension , the CONSORT group developed this elaboration and explanation document from a review of the literature to provide examples of adequate reporting . This extension , in conjunction with the main CONSORT Statement and other CONSORT extensions , should help to improve the reporting of RCTs performed in this field
