1 · What the graph read from it

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.

2 · The registry

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: Coughing, as one of the most common symptoms of the respiratory system in children, has a variety of etiologies. This study aimed to explore the predictive value of fractional exhaled nitric oxide (FeNO) combined with pulmonary ventilation function tests for airway hyperresponsiveness (AHR) in children with chronic cough. Methods: A total of 157 children with chronic cough who visited Chengdu Women and Children's Central Hospital from January 2020 to January 2024 were included. They were divided into a positive bronchial provocation test group (n=69) and a negative bronchial provocation test group (n=88) based on the results of the bronchial provocation test. The pulmonary ventilation function parameters and FeNO levels of the two groups were compared, and the predictive value of each index for AHR was evaluated through the receiver operating characteristic (ROC) curve. Results: The forced expiratory volume in the first second (FEV1), FEV1/forced vital capacity (FVC), forced expiratory flow at 25% of FVC exhaled (FEF25), forced expiratory flow at 50% of FVC exhaled (FEF50), forced expiratory flow at 75% of FVC exhaled (FEF75), and maximum mid-expiratory flow (MMEF) of the positive provocation group were significantly lower than those of the negative provocation group, and the FeNO level was significantly higher, with statistically significant differences (P<0.05). Further analysis through the ROC curve revealed that MMEF had the highest predictive efficacy for AHR [area under the curve (AUC) =0.88, 95% confidence interval (CI): 0.82-0.94]; when FeNO was combined with pulmonary ventilation function parameters, the combination of MMEF and FeNO had the best predictive efficacy (AUC =0.91, 95% CI: 0.86-0.96), with optimal cut-off values of 67.05% and 20.50 ppb. Conclusions: The combination of FeNO and MMEF can effectively predict AHR in children with chronic cough and has significant clinical value for the differential diagnosis of chronic cough etiology.
