Headline vs Study
- Headline: Up to 25 Cups of Coffee a Day Still Safe for Heart Health, Study Says.
- Press-release: Coffee Not as Bad for Heart and Circulatory System as Previously Thought.
- Meeting abstract: No Statistically Significant Cross-sectional Correlation in Arterial Stiffness for Individuals Who Drink >3 Cups of Coffee/day Group (>25 Excluded). No Causation Established; 25-cup Drinkers Not Specifically Studied.
Contrary or Null Findings
- "Despite intensive, state-of-the-art, and often creative interventions conducted by seasoned investigators, all 5 of the studies considered below failed to alter the trajectory of weight gain in their participants compared with controls."
- RCT: "In this low-income, adolescent population, neither of the family-based interventions improved BMI or health-related secondary outcomes."
- RCT: No Effect of a School-Based Comprehensive Intervention for Childhood Obesity in China on BMI.
- RCT: "the intervention did not demonstrate a significant increase in nurse visits for obesity care..."
- RCT: "There seems to be no differential effect of weight loss or its interaction with macronutrient composition on measures of satiety."
- RCT: "A smartphone based attentive eating intervention and standard dietary advice did not result in reduced energy intake or greater weight loss at 4 or 8 week follow-up than standard dietary advice alone."
- RCT: "The use of AKTIDIET® [app] to support health advice for weight loss cannot be recommended."
- "There was no difference in adjusted hospital mortality across BMI strata in subjects with moderate to severe ARDS."
- "Our [mendelian randomization] findings support that T2DM and kidney disease increase TMAO levels and observational evidence for cardiovascular diseases may be due to confounding or reverse causality."
