Subjective swallowing symptoms and related risk factors in COPD.
Article in ERJ open research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesThis study aimed to investigate the prevalence of subjective (
methodsA total of 571 patients with COPD, investigated in a stable phase, participated in this multicentre study (335 females, 236 males; mean age: 68.6 years (sd 7.7)). Data were derived from spirometry, a questionnaire and a 30-metre walking test.
resultsIn total, 33% (n=186) patients reported at least some degree of swallowing problem. The most frequently reported symptom was food lodging in the throat (23%). A significant relationship was found between swallowing symptoms and dyspnoea, assessed as modified Medical Research Council (mMRC) ≥2 compared with <2 (46%
conclusionSubjective swallowing symptoms seem to be a common problem in patients with stable COPD. This problem is seen in all stages of the disease, but is more common in symptomatic patients and in patients with lower physical capacity.
