  "abstract": "In this research paper by Little and colleagues (BMJ 2023;380:e074224, doi:10.1136/bmj‑2022‑072924, published 9 February 2023), incorrect data for ERR (excess relative risk)/Gy for one study (Chen et al 2019) were used. The corrected entries use grade ≥3 cardiac events, rather than all cause mortality, resulting in ERR/Gy using a heart dose of 0.756 (95% confidence interval (CI) −0.397 to 4.108) and using a left ventricle dose of 0.044 (−0.679 to 2.399). We also overlooked ERR/Gy for ischaemic heart disease and other heart disease in another study (Kashcheev et al 2017). These entries (ischaemic heart disease, 0.42 (95% CI 0.25 to 0.60); heart disease other than ischaemic heart disease, 0.36 (95% CI 0.14 to 0.59)) should replace the ERR/Gy data used in the meta-analysis for the same endpoints in this cohort, derived from an earlier analysis of this cohort (Ivanov et al 2006, 2007).",
