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

Fractional exhaled nitric oxide (FeNO) is an internationally recognized biomarker for type 2 airway inflammation. With the increasing promotion and widespread use of FeNO testing in China, Chinese experts have previously published consensus regarding FeNO measurement principles and clinical applications for adults and children respectively. However, in clinical practice, due to insufficient understanding of the detection principles, quality control requirements, and standardized operational procedures, questions have been raised on FeNO measurement's accuracy and clinical significance, which indeed limit the widespread application of FeNO in clinical settings. Based on the achievements in this area worldwide, this consensus elaborated the details and development on the principle of FeNO instruments, FeNO detection method, operation process, quality control, clinical significance, etc. Hopefully, this consensus document can be used to promote standardized FeNO testing protocols and better serve the precise diagnosis and treatment of airway diseases.
