Feasibility and Psychometric Properties of the Adjusted DSWAL-QoL Questionnaire for Dysphagic Patients with Additional Language and/or Cognitive Impairment: Part I.
Article in Dysphagia, 2017. 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
The Swallowing Quality-of-Life questionnaire (SWAL-QoL) is considered the gold standard for assessing health-related quality of life in people with dysphagia. However, many dysphagic patients struggle to complete this questionnaire because of additional functional sequelae such as language impairment and cognitive disorders. In this study, we sought to develop an adjusted Dutch version of the SWAL-QoL (aDSWALQoL) and to evaluate its psychometric properties and feasibility compared with the original questionnaire. We developed the aDSWAL-QoL based on recommendations from previous literature. The feasibility, internal consistency, test-retest reliability, and criterion validity of the aDSWAL-QoL were evaluated in 78 dysphagic patients, among whom 43 had additional language and/or cognitive impairments (DysLC). Statistical analyses were performed using SPSS 20.0. The aDSWAL-QoL had a higher degree of feasibility for the DysLC group. We obtained high Cronbach's α coefficients for total scale and for almost all subscales. Total aDSWAL-QoL scores showed excellent testretest agreement and good criterion validity with respect to the DSWAL-QoL. Almost all subscales showed significantly moderate to good test-retest agreement and criterion validity. However, the psychometric properties of the 'Food selection' subscale were inadequate. The aDSWAL-QoL is a feasible, reliable, and valid tool for use with DysLC patients. Conversion of the aDSWAL-QoL into an audio computer-assisted self-administered format should be investigated. The construct validity of the aDSWAL-QoL will be evaluated in a separate report.
