Advanced cancer patients' knowledge and opinions regarding the French law on advance directives: a multicenter cross-sectional study.

The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03664856 (The Opinion of Patients With Cancer on the Claeys-Leonetti Law, on Euthanasia and the Search for Determining Factors), which is not on this map.

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.

Abstract
purposeAdvance directives (AD) are a key tool within advance care planning (ACP), intended to support patient autonomy and guide end-of-life care. Despite their legal recognition in France, their use in the general population remains limited. Moreover, data on AD use among patients with advanced cancer, a population particularly concerned by end-of-life decisions, remain scarce. This study aimed to assess the knowledge and opinions regarding AD among patients with advanced cancer in France who were receiving specialized palliative care.
methodsBetween 2016 and 2020, we conducted a multicenter cross-sectional study across 14 palliative care departments in France. Patients with advanced cancer completed a standardized questionnaire assessing their awareness, use, and perceptions of AD, along with sociodemographic and clinical characteristics.
resultsA total of 331 patients were included. Among them, 53.5% were aware of AD, and 23.6% had completed one. Overall, 72.2% of patients supported legally binding AD, and 66% opposed fixed expiration dates; among those favoring time limits, most chose 1-3 years. In multivariable analysis, a higher educational level and prior treatment during the curable phase were independently associated with knowledge of AD, while completion was associated with older age, higher education, and the absence of ongoing cancer treatment. A higher educational level was also associated with favoring legally binding AD.
conclusionFrench rates of AD completion remain modest. Our findings highlight the need for personalized, repeated discussions about end-of-life preferences and for enhanced clinician training in ACP. AD should be approached as a flexible tool within broader patient-centered discussions. CLINICAL TRIALS IDENTIFIER: NCT03664856.
