Evaluation of central venous catheter and other risk factors for mortality in chronic hemodialysis patients with COVID-19 in Brazil.

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
purposeHemodialysis patients with COVID-19 are at increased risk of death. We aimed to describe the characteristics of a cohort of Brazilian hemodialysis patients with COVID-19 and assess their mortality rate and risk factors for death.
methodsRetrospective cohort study of 741 Brazilian hemodialysis patients with confirmed COVID-19 from Feb-Dec/2020, of 52 dialysis centers of the country. We analyzed comorbid conditions, sociodemographic factors, and dialysis-related parameters. To detect risk factors for mortality in hemodialysis patients, we performed multivariable Cox proportional hazard regression analysis. Survival was analyzed by Kaplan-Meier.
resultsFrom 9877 hemodialysis patients, 741 were diagnosed with COVID-19. Mean age was 57 ± 16 years, 61% were male, and 51% white. The most frequent symptoms were fever (54.1%), cough (50.9%), and dyspnea (37.2%); 14.2% were asymptomatic. There were 139 deaths (18.8%), with 66% within the disease's first 15 days. 333 patients (44.9%) required hospitalization, and 211 (28.5%) were admitted to an intensive care unit. The cumulative probability of survival at 90 days of diagnosis was 79% (95% CI 76-82%). In the fully adjusted multivariate model, the risk factors significantly associated with death were diabetes mellitus (HR 1.52, 95% CI 1.05-2.19, P = 0.026), use of a central venous catheter (CVC) (HR 1.79, 95% CI 1.22-2.64, P = 0.003), age (HR 1.03, 95% CI 1.01-1.04, P < 0.001), and origin from the North vs. Southeast region (HR 2.60, 95% CI 1.01-6.68, P = 0.047).
conclusionsHemodialysis patients using a CVC as the vascular access, aside from diabetic and elderly ones, should be closely monitored due to their high risk of death in the course of the COVID-19.
