Deep Inspiration-Provoked Cough: A Sign of Cough Reflex Arc Hypersensitivity.
Article in Lung, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Deep inspiration-provoked cough (DIPC) is a form of allotussia. Allotussia is thought to be a manifestation of cough reflex arc hypersensitivity but objective evidence about this is lacking. 36 subjects with chronic cough and 25 healthy subjects underwent mannitol and citric acid cough provocation tests. DIPC was defined as two or more coughs after deep inhalation of an empty mannitol capsule. Citric acid was administered utilizing a dosimetric nebulizer during controlled tidal breathing. Nine subjects demonstrated DIPC, 8/36 subjects with chronic cough and 1/25 healthy subjects (p = 0.048). The concentration of citric acid to provoke five or more coughs (C5) was 23.4 (63.8) mM among subjects with DIPC and 750 (2941) mM among the subjects without it (p = 0.006). The number of deep inspiration-provoked coughs correlated with the citric acid C5 (Rs -0.38, p = 0.002). In conclusion, DIPC, a form of allotussia, is associated with cough reflex arc hypersensitivity.Trial Registration Number.ClinicalTrials.gov database KUH5801136.
