1 · What the graph read from it

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.

2 · The registry

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

backgroundDecisional capacity is an important requirement for assisted suicide, which has been legalized in an increasing number of countries. While several instruments have been developed over the past few decades to assess the capacity to consent to treatment, little is known about their applicability to assessing capacity in the context of requests for assisted suicide.

methodsSystematic review of instruments assessing decisional capacity published up to March 2024. Data concerning criteria for determining decisional capacity, psychometric properties, and other aspects were extracted from all instruments included. Selected instruments were analyzed regarding their applicability to requests for assisted suicide.

resultsWe identified 23 instruments assessing the capacity to consent to treatment. There is considerable heterogeneity regarding the criteria utilized for assessing decisional capacity and their operationalization. Next to more cognitive abilities, some instruments directly incorporated emotions and values. Five instruments were assessed for applicability to requests for assisted suicide. The framing of decisional capacity within the context of disease and treatment options frequently limits the application of instruments to assess decisional capacity in the context of requests for assisted suicide.

conclusionsNo instrument could be identified that could be applied to assessing decisional capacity in the context of requests for assisted suicide without any limitations or without necessitating adjustments. Further normative and empirical work is required for developing an instrument that could be applicable in this context.
