Number needed to treat
Changing to a less severe quartile in the main outcome compared to the participant's baseline score was considered a criterion to define responders to the intervention. The quartiles of ‘emotional eating’ (DEBQ) at baseline were established at 1.56 (Q1), 2.50 (Q2), and 2.85 (Q3). Posttreatment, 15 individuals (44.1%) in the experimental group reduced their score to an inferior quartile. In the control group, only 2 patients (5.7%) experienced such improvement. The ARR obtained was 37.67% (95%CI = 18.87%–56.46%), with a NNT of 3 (95%CI = 1.8–5.3). In the follow‐up assessment, 17 participants (48.6%) in the experimental group experienced an improvement compared to 2 (6.1%) in the control group, which resulted in an ARR of 42.51% (95%CI = 24.06%–60.96%), with a NNT of 3 (95%CI = 1.6–4.2).The second criterion used to calculate the NNT was the RCI, which was established at 0.72 points posttreatment. With this criterion, 5 individuals (14.7%) in the intervention group experienced a reliable improvement. In the control group, no reliable changes were appreciated. The ARR obtained in this case was 14.71% (95%CI = 2.80%–26.61%), with a NNT of 7 (95%CI = 3.8–35.7). In the follow‐up assessment, the RCI was established at 1.10 points, and in this case, 3 individuals in the ‘Mindful eating’ group (8.6%) experienced a reliable improvement. The control group, again, showed no reliable changes. A not statistically significant ARR was obtained (8.57%; 95%CI = −0.70%–17.85%), and therefore, the NNT was not calculated.
