Measuring the quality of life of people with dementia in nursing homes in Germany - the study protocol for the Qol-Dem Project.
Article in Psycho-social medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundQUALIDEM is a standardized dementia-specific quality of life (Qol) measurement, which was developed and validated in the Netherlands. A German version has been available since 2008. This study protocol describes the design and methodology for the quality of life of people with dementia (Qol-Dem) project.
objectiveThis project aims to evaluate the reliability and validity of the German version of the QUALIDEM.
methodDue to the lack of both a universal definition of Qol and of standards to verify the validity of Qol measurements, this study is divided into three phases. The aim of the first theoretical phase is the development of a dementia-specific Qol model as a result of a meta-synthesis of qualitative studies. The second empirical phase consists of the three following steps: (a) an investigation of the scalability and internal consistency of the measure, (b) an evaluation of the interrater and intrarater reliability, and (c) an extensive evaluation of the validity of the QUALIDEM. The resulting Qol model (phase 1) will be used for the selection of appropriate comparators for validity testing. In the third phase, the QUALIDEM will be adapted, if necessary, based on the knowledge generated in the first two phases.
conclusionThe findings of the Qol-Dem project should deliver an accurate assessment of the psychometric properties of the German version of the QUALIDEM. The results will contribute to the further development of the instrument. Furthermore, the results will contribute to the theoretical development of the concept of Qol among people with dementia.
