Five studies showed some or positive association, one found weak association and for one study the association was unclear. Overlap of primary studies was \u2018very slight\u2019. Meta-analysis of two studies concluded fully or partially edentulous individuals were more likely to be malnourished or at risk of malnutrition, (RR\u2009=\u20091.095, 95% CI 1.007 to 1.190,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.033.
