Opioid prescribing patterns at the end of life in an asian advanced cancer cohort: differences by palliative care consultation status.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeOpioid prescribing at the end of life varies widely across clinical contexts, yet real-world evidence from Asian advanced cancer populations remains limited. This study characterized end-of-life opioid prescribing patterns and examined differences according to palliative care consultation status.
methodsWe conducted a retrospective cohort study using tertiary hospital clinical records linked to Korean National Health Insurance claims data. Patients with advanced cancer who received a palliative care consultation were matched 1:1 with those without consultation using propensity scores. Opioid prescribing during the last 30 days of life was evaluated, including time-specific patterns across three intervals (30-15, 14-8, and 7-0 days before death) and opioid strength (strong vs. weak).
resultsAmong 18,048 eligible patients, 3,742 were matched in each group. Opioid prescriptions were more common among patients who received palliative care, with the largest differences observed 30-15 days before death and narrowing toward the final week. Strong opioid use remained consistently higher in the palliative care group across all intervals, whereas weak opioid use showed minimal variation. Differences were most pronounced in older adults and in stomach, colorectal, and pancreatobiliary cancers.
conclusionPatients who received a palliative care consultation showed different patterns of end-of-life opioid prescribing, especially for strong opioids. Understanding such variation may support ongoing efforts to improve symptom management near the end of life.
