Feasibility and Tolerance of High-Intensity Interval Training in Adults With Cystic Fibrosis.
Article in Archives of rehabilitation research and clinical translation, 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
Objectives: To assess the feasibility and the tolerance of a high-intensity interval training (HIIT) program compared with conventional rehabilitation during a 3-week hospital stay in adults with cystic fibrosis (CF) and to analyze the effectiveness and impact on health indicators of HIIT. Design: A prospective, 2-center, open-label, randomized, controlled study. Setting: Cystic Fibrosis Resource and Expert Centers, Roscoff and Giens (France). Participants: A total of 62 adults (aged: 36.1±11y; M/F ratio: 1.3) with CF were included. Interventions: Intervention group performed 3 HIIT sessions, alternating 30 seconds of work and 30 seconds of rest repeated 6 times ≥80% of maximum heart rate, and 2 low-intensity sessions per week. Control group (conventional rehabilitation) performed 5, 20-to-30-minute sessions per week at the first aerobic ventilatory threshold. Main Outcome Measures: (1) Feasibility was evaluated by compliance; (2) tolerance by the degree of dyspnea and adverse effects; (3) effect on physical capacity using the 6-minute walk, body composition, the forced expiratory volume in 1 second (FEV1), and the multidimensional dyspnea profile; (4) impact on health indicators by the Fibrosis Quality of Life Questionnaire and the Hospital Anxiety and Depression; and (5) participant satisfaction by the STARFISH (perception of physical activity) and the Physical Activity Enjoyment Scale. Results: Compliance with exercise sessions was marginally higher but statistically significant in the HIIT (93.3%) than the control (86.7%) group, Conclusions: HIIT is feasible, safe, and well tolerated and could be used as a timesaving alternative to conventional treatment, particularly in people under CFTR modulator therapy.
