A possible protective role for Bacillus Calmette-Guérin therapy in urinary bladder cancer in the era of COVID-19: a brief report.
Article in Clinical and experimental vaccine research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Given the systemic immunogenic effects of Bacillus Calmette-Guérin (BCG) therapy in patients with bladder cancer and its non-specific immunogenic effects in viral respiratory diseases, we aimed to study severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in bladder cancer patients with a history of BCG therapy. In the present study, all bladder cancer survivors with a history of BCG therapy were identified and included in the study according to the data recovered from the UORC (Uro-Oncology Research Center) registry database. These patients were followed up in terms of acquiring coronavirus disease 2019 (COVID-19). Among the studied patients, 102 eligible bladder cancer patients with a history of BCG therapy entered the study. The males constituted the majority of the patients (86.3%), and more than half of the study population (55.9%) were above 65 years old. Among the understudy patients, 12.7% were confirmed for COVID-19. The study results did not show a statistically significant association between the time and number of BCG therapy courses and SARS-CoV-2 infection. Although no statistically significant association was observed between receiving BCG therapy and developing COVID-19, the infection rate in patients who had recently received BCG therapy was lower than those who had received therapy more than a year ago.
