Contrary or Null Findings

• "Contrary to our hypothesis that low n-3 PUFA levels would create risk, we found that while higher AA was associated with greater depression severity at baseline, low AA unexpectedly predicted subsequent suicide attempts, the more so in higher-risk patients."
• "Contrary to traditional views of adolescent weight status, physical activity (i.e., school-based, individual, active transport) and nutritious consumption (i.e., fruits, vegetables, milk) were not associated with weight status, when considering social factors. These findings challenge the utility of public health approaches that target individualistic behaviours as critical risk factors in “obesity prevention” efforts in adolescence."
• "Contrary to hypotheses, results showed that neither BMI/body fat nor metabolic indices were related to suicidal ideation, nor did social act as a moderator of these associations."
