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
Background: Human adenoviruses (HAdVs) are prevalent pathogens responsible for respiratory infections. In this study, we examined the relationship between adenovirus viral loads in bronchoalveolar lavage fluid (BALF) and the severity of adenovirus pneumonia in children. Methods: The medical records of patients admitted to Guangzhou Women and Children's Medical Center with confirmed adenovirus pneumonia were analyzed in a prospective manner. We evaluated the potential link between the severity of the disease and the viral load, which was measured using real-time polymerase chain reaction (PCR) on the BALF of pediatric patients. Furthermore, the study investigated the connection between viral loads in BALF and the progression of the illness. Results: In hospitalized pediatric patients with adenovirus pneumonia, the viral loads found in BALF were positively associated with the severity of the disease during the acute phase (P<0.05). In addition, lactate dehydrogenase (LDH) and C-reactive protein (CRP) levels were positively associated with viral loads in BALF, whereas albumin (ALB) levels showed a negative relationship (P<0.05). In addition, In addition, The receiver operating characteristic (ROC) analysis indicated that viral loads in BALF displayed great potential for predicting severe adenovirus pneumonia, with a cut-off value of >187,500 copies/mL, which achieved a sensitivity of approximately 77.27% and a specificity of 80.65%.Moreover, viral loads in BALF from patients at the acute stage of the disease were positively correlated with fever duration and length of stay (LOS) at the hospital, and viral loads declined quickly during the recovery stage (P<0.05). Conclusions: Our findings indicated a significant correlation between viral loads in BALF from patients with adenovirus pneumonia and the severity of the disease. We suggested that viral loads can serve as potential biomarkers for identifying severe cases and predicting the progression of illness.
