Effects of Cough Training and Inspiratory Muscle Training on Cough Strength in Older Adults: A Randomized Controlled Trial.
Trial report in Lung, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeWhile the need for preventive strategies to reduce the incidence of aspiration pneumonia has been indicated, it is also important to investigate effective training methods to improve cough function, which is associated with the development of aspiration pneumonia. This study aimed to investigate whether a 4-week home-based unsupervised cough training (CT) or inspiratory muscle training (IMT) program was effective in improving cough strength in older adults.
methodsFifty-three ambulatory older adults without airflow limitations were randomly assigned to one of three groups: a CT group (n = 18), an IMT group (n = 18), or a control group (n = 17). The CT and IMT groups performed home-based unsupervised training with a device for 4 weeks. Cough strength (cough peak flow), forced vital capacity, and respiratory muscle strength were assessed at the 4-week and 16-week follow-up. Intention-to-treat analyses were performed to investigate differences between the three groups using linear mixed models.
resultsAt the 4-week follow-up, the CT group showed significant increases in cough peak flow and forced vital capacity compared with the control group, while the IMT group showed significant increases in inspiratory muscle strength compared with the cough training and control groups. At the 16-week follow-up, the CT group showed a significant increase in cough peak flow compared with the IMT group.
conclusionThese preliminary results suggest that a 4-week home-based CT program may have short-term effectiveness in improving cough peak flow in ambulatory older adults.
