High rates of viral co-detection in outpatient children with acute respiratory infections after the easing of preventive measures against Covid-19 in Germany.

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
backgroundFollowing the easing of preventive, non-pharmaceutical COVID-19 interventions (NPIs) during the late phase of the pandemic, acute respiratory infections (ARI) in children reemerged. We investigated the viral etiology, seasonality and clinical characteristics of children with ARI treated in primary care practices during this period.
methodsWe conducted a prospective, observational study on children ≤ 14 years of age, presenting with acute upper (URTI) or lower (LRTI) ARI in five pediatric primary care practices in Wuerzburg, Germany, from 10/2021 to 05/2022. A maximum of eight children per practice were included on one predefined day per week. Oropharyngeal swabs were analyzed using (multiplex) PCR for 18 viral pathogens.
resultsA total of 521 children (median age 3.3 years; IQR 1.6–5.5; 52% male) with ARI were enrolled (28% LRTI). At least one virus was detected in 85%, with human rhinovirus (HRV) (30%), Respiratory Syncytial Virus (RSV) (22%), and SARS-CoV-2 (16%) being the most frequent viruses. Co-detection (≥ 2 viruses) occurred in 156 (30%) patients, were most frequent in children < 2 years of age (38% of 164), and their rate decreased with increasing age (p = 0.012). Bocavirus (88% of 56), adenovirus (80% of 48) and endemic coronaviruses (70% of 42) showed the highest proportion of co-detection. RSV and human metapneumovirus (hMPV) were predominant in LRTI, whereas HRV and SARS-CoV-2 were more prevalent in URTI. The LRTI rate was 32% of 288 mono-detections and 23% of 156 co-detection.
conclusionsDuring fall/winter 2021/2022, viral co-detection were common, possibly as a consequence of easing COVID-19-related NPIs, but were not associated with more severe clinical characteristics.
