Conclusions This study suggests that previous meta-analyses of a low-quality body of evidence may have considerably overestimated the effects of plate size on consumption. However,导致偏倚风险增加,除使用较大餐盘时会留有较多的剩余食物在盘子上之外, leading to increased risk of bias. In the first pre-registered study to date, the possibility of a clinically significant effect in either direction cannot be excluded. Well-conducted trials of tableware size in real-world field settings are now needed to determine whether changing the size of tableware has potential to contribute to efforts to reduce consumption at population-level.
