Giving meaning to the scores of the Amsterdam instrumental activities of daily living questionnaire: a qualitative study.
Article in Health and quality of life outcomes, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
backgroundEveryday functioning is a clinically relevant concept in dementia, yet little is known about the clinical meaningfulness of scores on functional outcome measures. We aimed to establish clinically meaningful scoring categories for the Amsterdam Instrumental Activities of Daily Living Questionnaire (A-IADL-Q), representing no, mild, moderate and severe problems in daily functioning.
methodsInformal caregivers (n = 6) of memory-clinic patients and clinicians (n = 13), including neurologists and nurse specialists, working at various memory clinics in The Netherlands. In focus groups, participants individually ranked nine summaries of fictional patients from least to most impairment in daily functioning. Then, they placed bookmarks to demarcate the thresholds for mild, moderate and severe problems. Individual bookmark placements were then discussed to reach consensus. Clinicians completed a survey in which they placed bookmarks, individually.
resultsWhile individual categorizations varied somewhat, caregivers and clinicians generally agreed on the thresholds, particularly about the distinction between 'no' and 'mild' problems. Score categories were no problems (T-score ≥ 60), mild problems (T-score 50-59), moderate problems (T-score 40-49), and severe problems in daily functioning (T-score < 40), on a scale ranging 20-80.
conclusionsOur findings provide categories for determining the level of functional impairment, which can facilitate interpretation of A-IADL-Q scores. These categories can subsequently be used by clinicians to improve communication with patients and caregivers.
