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
introductionA broad range of common respiratory viruses contributes substantially to the burden of acute respiratory infections (ARIs) across all age groups. However, data on their epidemiology, seasonality, and clinical impact in Eastern Europe remain limited.
methodsWe conducted a retrospective laboratory-based surveillance study including patients evaluated for ARIs at the National Institute for Infectious Diseases "Prof. Dr. Matei Balș", Bucharest, Romania, between November 2022 and October 2025. Respiratory samples were tested using multiplex real-time RT-PCR panels detecting multiple respiratory viruses. The present analysis focused on adenovirus (AdV), enterovirus (HEV), rhinovirus (HRV), parainfluenza virus (PIV), human coronaviruses (CoV), human bocavirus (HBoV), and human metapneumovirus (MPV). Epidemiological characteristics, detection patterns, and clinical outcomes were analyzed.
resultsAmong 4930 patients tested, 1709 (34.7%) had at least one of the studied viruses detected, corresponding to 2144 viral detections (22.2% patients with viral codetections). HRV was the most frequently detected virus. Also, viral codetections most commonly involved HRV. Analysis of monthly detections across the three seasons studied demonstrated virus-specific temporal patterns. Specifically, MPV demonstrated a more consistent winter-spring detection pattern, whereas HRV was detected throughout the study period. Overall, 50.2% of patients required hospitalization, with the highest rates observed among patients with CoVs and MPV detection. Requirement of supplemental oxygen was more common in patients hospitalized with MPV (28.4%) and PIV (24.6%). Patients with viral codetections had higher hospitalization rates compared with those with monodetections (57.7% vs. 48.1%; OR = 1.47; p < 0.001), although no significant differences were observed in requirement of supplemental oxygen, ICU admission, or length of hospital stay.
conclusionsAdV, HEV, MPV, PIV, HBoV, CoV and HRV accounted for a substantial proportion of viral detections among patients evaluated for ARIs in routine clinical practice. The predominance of HRV and the frequent occurrence of viral codetections highlight the complexity of respiratory viral epidemiology revealed by multiplex molecular diagnostics. Broader surveillance of respiratory viruses may improve understanding of respiratory infection dynamics in the post-pandemic period.
