结局指标
主要结局
Changes in Brain Response to Food Cues in the Insula
时间窗: 1 hour
Functional magnetic resonance imaging (BOLD signals) while patients view food vs. non-food cues. The effect size z-score represents the magnitude of the activation in that area to food cues vs. non-food cues. The z-score is the estimated response magnitude in that area compared to the overall mean. Negative numbers indicate values lower than the mean and positive numbers indicate values above the mean.
次要结局
