Single-center study on SARS-CoV-2 infection in patients affected by CML: Vaccination status and bosutinib therapy as possible protective factors for hospitalization.

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 pandemic had a considerable impact among haematological patients. On the other hand, the effect of this disease on patients (pts) affected by Chronic Myeloid Leukemia (CML) is not clearly defined.
objectivesThe primary objective of this study was to evaluate mortality-hospitalization rates and possible protective factors for hospitalization in CML pts affected by COVID.
methodsWe collected data from CML patients followed at our institution whotested positive for SARS-CoV-2 infection. The following variables were assessed: demographical data, type of TKI therapy, vaccination status, presence of cardiovascular disease (CVD), period of infection, COVID-19 presenting symptoms, severity and mortality. Data were collected retrospectively and then analysed in univariate and multivariate analysis.
resultsOut of a total of 325 CML pts treated at our institution, we recorded 72 SARS-CoV-2pts (22%) who tested positive with a SARS-CoV-2 PCR assay. Twenty two were infected in 2020 (30%), 16 patients in 2021 (22%) and 34 in 2022 (46%); with a hospitalization rate of 27%, 25% and 3% respectively. Of the 72 confirmed infections, 13 pts (18%; (CI) 10-28) were asymptomatic and 48 (66%; CI: 55-76) had mild symptoms. A total of 11 pts were admitted to hospital and 3 of these required ICU admission. No deaths were recorded. The probability of hospitalization was significantly reduced if patients were vaccinated (odds ratio OR 0.037 with CI: 0-0.33 p 0.002) or treated with Bosutinib (OR 0.06 with CI: 0-0.5 p 0.008).
conclusionIn the present study, no significant increase in mortality was noted among patients with CML as compared to the general population inItaly. Vaccination and treatment with bosutinib were identified as baseline characteristics that were associated with a decreased risk of hospitalitazion resulting from COVID-19 infection.
