The CoughRetrain Program: Restoring Control Through a Non-pharmacological Intervention.
Article in Lung, 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
purposeNon-pharmacological cough interventions are recommended for refractory chronic cough (RCC), yet structured development processes and integration of behavioral theory are rarely described. We report on the development and feasibility of CoughRetrain, a theory-informed telehealth behavioral program that integrates behavior-change strategies to support voluntary control of coughing in RCC.
methodsCoughRetrain was developed following Medical Research Council guidance through staged problem identification, evidence review, multidisciplinary refinement, remote adaptation, and formative testing in interstitial lung disease. The final five-session individual program integrates education, graded suppression practice, motivational interviewing, and goal setting. A single-group feasibility pilot in adults with RCC assessed adherence, fidelity, adverse events, general self-efficacy (New General Self-Efficacy Scale), cough-specific self-efficacy (Cough-Specific Self-Efficacy Scale), cough-related quality of life [Leicester Cough Questionnaire (LCQ)], cough severity visual analogue scale (CS-VAS), and 24-hour objective cough frequency.
resultsTwelve participants were enrolled, and eleven (median age 51 [38-63] years; 55% female; median cough duration 6 [3-20] years) completed the program. All core components were delivered. Two non-serious adverse events occurred (urticaria; headache). General self-efficacy remained stable (mean change 0.04 ± 0.19). Cough-specific self-efficacy increased by 0.3 ± 0.6. LCQ increased by 3.6 ± 3.0 points (95%CI 1.5 to 5.6). CS-VAS decreased by 18.8 ± 25.0 mm (95%CI -35.7 to -1.9), and 24-hour cough frequency decreased by 48% (95%CI -74% to +3%).
conclusionsCoughRetrain is a safe and feasible telehealth intervention for RCC developed through a transparent, patient-informed process. Preliminary findings align with behavioral cough literature. Larger controlled studies evaluating long-term efficacy are warranted.
