Prognostic factors of mortality in patients with cancer infected with COVID-19: a systematic review protocol.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe COVID-19 pandemic has resulted in many cases of infection and deaths worldwide. Patients with cancer are a high-risk group for COVID-19-related death. However, a systematic summary of the prognostic factors related to mortality in these patients is limited. We systematically summarise the evidence on the prognostic factors of mortality in patients with pre-existing cancer, infected with COVID-19. METHODS AND ANALYSIS: We will address the prognostic factors for mortality, including cohort studies of adult patients with cancer infected with COVID-19. We will search MEDLINE, Embase and Cochrane Central Libraries for data from December 2019 to the present day. The prognostic factors for mortality include general, cancer-related and clinical characteristics. We will not limit the COVID-19 severity, cancer type and follow-up period of the included studies. Two reviewers will independently and in duplicate conduct reference screening, data abstraction and risk of bias assessment. We will perform a random-effect meta-analysis to calculate the pooled relative effect estimates for each prognostic factor of mortality. We will assess the risk of bias for each included study and rate the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. This study will provide information about high-risk groups for mortality in patients with cancer infected with COVID-19. ETHICS AND DISSEMINATION: This study will use only the published references and would not need to obtain ethical approval. We will disseminate our study findings through a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023390905.
