    Covariates: Our analysis included key sociodemographic data including measures of deprivation, household composition, occupation and key worker status, educational attainment and exposure to others, defined within Supplementary eTable 1.
    suggested: None

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    However, there were limitations. Most notably, this analysis is generalisable to the 52.4% of the English population with coded BMI data within their health care records in the 10 years preceding the pandemic. In England, height and weight are collected as part of routine care by trained staff using medical grade equipment. Nevertheless, family practice incentivisation schemes and differential take-up rates to population level vascular screening programmes means that data is not missing at random [20]. Previous analysis has shown that women, those who attend their family doctor more often, who come from more deprived areas, who have a high or low BMI and have a greater number of comorbidities are more likely to have a coded BMI value [20]. Nevertheless, it has been demonstrated that missing data within clinical records can provide unbiased estimates of adjusted exposure-outcome associations under a wide range of missing data assumptions [25]. In addition, primary care data in England provide some of the most detailed electronic health-care records internationally and are routinely used to identify individuals at risk of chronic and infectious diseases, including COVID-19 mortality [19, 26], giving this study real world utility. This study utilized data from the 2011 Census, therefore any sociodemographic changes within the last decade will not be reflected in the analysis. Although we adjusted for factors related to the risk of SARS-CoV-2 exposure, including household composi...

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
