The adverse impact of cytomegalovirus infection on intensive care units outcomes in critically ill COVID-19 patients: a single-center prospective observational study.

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
purposeTo assess the incidence and clinical impact of CMV infection in critically ill COVID-19 patients, examining ICU and hospital mortality, and length of hospital stay.
methodsIn this single-center, prospective observational study (March 2020 - September 2022), 431 patients with COVID-19 pneumonia and moderate to severe ARDS were included. An active CMV surveillance protocol was implemented, analyzing CMV DNA in plasma and bronchoalveolar lavage (BAL). Clinical characteristics and outcomes were compared between CMV-COVID co-infected patients and those without CMV reactivation.
resultsCMV-COVID co-infection was detected in 14.8% (64/431) of the cohort. Patients with CMV-COVID co-infection exhibited significantly higher ICU mortality (43.8% vs. 13.6%; p < 0.001) and hospital mortality (48.4% vs. 13.6%; p < 0.001) compared to patients without CMV. CMV infection was an independent predictor of hospital mortality (OR 4.91; 95% CI 2.76-8.75; p = 0.019). Earlier CMV reactivation was associated with an increased risk of hospital mortality (HR = 0.94; 95% CI: 0.90-0.98; p = 0.003). Additionally, CMV-COVID patients had a higher incidence of ICU-acquired infections and a prolonged hospital stay.
conclusionsIn critically ill patients with SARS-CoV-2 pneumonia, CMV infection was frequently observed, and associated with increased ICU and hospital mortality. CMV co-infection correlated with a higher incidence of ICU-acquired bacterial and fungal infections and prolonged hospital stays. This emphasizes the importance of early CMV monitoring upon ICU admission, as timely detection and intervention could potentially mitigate its impact on patient outcomes.
