Table 1: Rigor
Ethics not detected. Sex as a biological variable Data extraction and quality assessment: Two authors (E.K. and C.P.) independently undertook data extraction for the following: first author, study type, time period of data collection, country of data collection, number of male and female patients, median or mean age, cancer treatment intervals prior to COVID-19 diagnosis or hospitalisation, unadjusted and adjusted odds ratios (ORs) or hazard ratios (HRs) for severe disease and death for each cancer subtype and for each cancer treatment subtype as well as the number of cancer patients with COVID-19 and cancer type. Randomization To examine the impact of age and sex on mortality among cancer patients … SciScore for 10.1101/2021.12.18.21267261: (What is this?)

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:This systematic review demonstrates a number of potential limitations with the currently available data and literature these include; (1) lack of contemporaneous non-cancer populations for comparative analysis 12,19,23,36,38,40; (2) heterogeneity of definitions between studies such as severity of COVID-19 as demonstrated by the 14 definitions of severity used across studies (Figure S13;) (3) predominantly retrospective nature of studies (Table S4, 75%); (4) variable follow up; (5) heterogeneity or poor description of the non-cancer control cohorts, such as use of non-hospitalised patients 12,21,29,36–38,44, or staff members with COVID-19 43; and (6) lack of detail relating to systemic cancer treatment 4,11,12,22,29,33,37,39,41,42,50,52,55–57,65,70–72,75,76,79–81,84,86–91. In those studies where a non-cancer cohort was utilised these data were generally historical or based on registry data and were not contemporaneous to the cancer cohort 12,19,36,38,43. Only three of the 19 studies that compared cancer cohort to a matched non-cancer cohort used propensity score matching 14,16,39. Therefore, within the published literature biases may be present as a result of unmeasured confounders. Utilising data from 19 studies with 3,926 patients with 38,847 non-contemporaneous non-cancer patients, we found that malignant disease is associated with an increased risk of severe or death from COVID-19 compared with non-cancer patients (RR 2.12; 95% CI, 1.76-2.62; p<0.001; I2=84.4%).
