Fractional exhaled nitric oxide at multiple flow rates in chronic cough: association with lung function and airway hyperresponsiveness.
Article in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe relationship between airway inflammation and airflow obstruction in patients with chronic cough remains unclear. This study aimed to evaluate the relationships between multi-flow fractional exhaled nitric oxide parameters (FeNO MATERIALS AND
methodsThis retrospective study enrolled 2205 chronic cough outpatients who underwent spirometry and multiple-flow FeNO measurements. Patients were stratified by airway function and FeNO levels for group comparisons, and Spearman's rank correlation was used. In a subgroup (
