In Table 2 (Study characteristics and estimated birth prevalence) and Fig. 2 (Pooled global birth prevalence of clubfoot), the estimate was noted as 3.57 (2.93–4.34) per 1000 births. However, Zhou et al. (2020) report this as per 10,000 births. The correct estimate is therefore 0.36 (0.29–0.43) per 1000 births. The error occurred during transcription and we have since confirmed with the authors that the denominator is 10,000 births. The correction of this estimate does not alter the main results or conclusions of the paper. The pooled global prevalence of clubfoot should be 1.10 (95%CI 0.93–1.28) instead of 1.18 per 1000 births (95% CI: 1.00–1.36), and the subgroup analysis of the WHO Western Pacific Region should be 0.62 (95% CI 0.38–0.86) instead of 0.86 (95% CI 0.60–1.11) per 1000 births. The authors apologise for any confusion this error may have caused and appreciate the understanding of the readers.
