Risk factors associated with cognitive impairment in patients with COVID-19: a protocol of systematic review and meta-analysis.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionCOVID-19 infections have become a global public health emergency. Although COVID-19 is primarily a respiratory disease, some of hospitalised patients exhibit cognitive impairment-related neurological damage. Using a systematic review and meta-analysis, we aim to investigate the risk factors for cognitive impairment in patients with COVID-19. METHODS AND ANALYSIS: This meta-analysis has been registered with the International Prospective Register of Systematic Reviews. From inception to 5 August 2022, we will search PubMed, Web of Science, Embase via Ovid, the Chinese Biological Medical Database and the Cochrane Central Register of Controlled Trials (CENTRAL) for relevant studies . We will also look for additional studies in the reference lists of selected articles. To ensure data quality and accuracy, only researches published in English and Chinese will be included. Fixed or random-effects model will be used to calculate the relative risk (RR) or odds ratio (OR) and 95% CIs for pooled data about dichotomous outcomes. We will also assess heterogeneity using Cochrane's Q and I ETHICS AND DISSEMINATION: Data will be extracted from published studies, so ethical approval is not required. The outcomes of this meta-analysis will be published in a journal with peer review. PROSPERO REGISTRATION NUMBER: CRD42022351011.
