Erratum to: Is self-weighing an effective tool for weight loss: a systematic literature review and meta-analysis

Erratum

Since publication of the original article [1], a reader observed an error in one of the studies that had been included. The study by VanWormer et al [2] 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.
