Reporting of systematic reviews of micronutrients and health: a critical appraisal.

ABSTRACT:

Background

The quality of nutrition-related systematic reviews (SRs) is an unstudied but important factor affecting their usefulness.

Objectives

The objectives were to evaluate the reporting quality of published SRs and to identify areas of improvement.

Design

Descriptive and exploratory analyses of the reporting quality (7 nutrition items and 28 SR reporting items) of all English-language SRs published through July 2007 linking micronutrients and health outcomes in humans were conducted. Factors that may be associated with reporting quality were also evaluated.

Results

We identified 141 eligible SRs of 21 micronutrients. Ninety SRs that included only interventional studies met a higher proportion of our reporting criteria (median: 62%; interquartile range: 51%
