Erratum to: Is self-weighing an effective tool for weight loss: a systematic literature review and meta-analysis
International Journal of Behavioral Nutrition and Physical Activity volume 13, Article number: 42 (2016)
Since publication of the original article , a reader observed an error in one of the studies that had been included. The study by VanWormer et al  presented the results as pounds and was mistakenly analysed in kg. The results have been re-analysed.
Comparing multi-component interventions including self-weighing with no intervention or minimal control is changed by 0.1 kg (3.3 kg, 95 % CI -4.1 to -2.8). The 95 % prediction intervals changed slightly (-6.7 to 0.05 kg versus previously -6.9 to 0.1). Figure 2 of the original article should have presented these results, as appears correctly within this erratum.
In addition, the mean difference between intervention and control groups for those with accountability changed from -3.6 kg (95 % CI -4.6 to -2.7 kg) to -3.5 kg (95 % CI -4.4 to -2.6 kg). This difference was approaching significance (p = 0.05) rather than previously being significant (p = 0.03). An amended version of Table 3 appears here to highlight these changes.
