The significance of a study depends on all three factors listed: the magnitude of the effect or relationship being measured, the size of the study, and the power of the study to detect that effect. A study may have a small effect size but still achieve statistical significance if the sample size is large enough, or it may have a large effect size but not achieve significance if the sample size is too small or the study lacks power. Therefore, all three factors are important in determining the significance of a study.
