A case of laryngopharyngeal reflux-associated chronic cough: Misinterpretation of treatment efficacy causes diagnostic delay.
Article in Journal of general and family medicine, 2020. 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
A 62-year-old woman presented with a dry cough lasting 18 months. She had previously been examined by multiple doctors, but no abnormalities were observed. Several medications such as rabeprazole and inhaled corticosteroids were administered as test treatments without any improvement. Therefore, the possibility of biological disease, including acid reflux, had been mistakenly ruled out. We examined the sputum gram stain. The result showed phagocyted normal bacterial flora, suggesting aspiration. Laryngoscopy revealed edema of the arytenoid cartilage. The patient was finally diagnosed with laryngopharyngeal reflux and silent aspiration. This case suggested that the ineffectiveness of proton-pump inhibitors cannot always exclude the presence of reflux disease and the usefulness of gram stain examination to detect silent aspiration.
