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

purposeA sudden unexpected death has significant negative impacts on patients, family caregivers, and medical staff in hospice/palliative care. This study aimed to clarify the incidence and associated factors of sudden unexpected death according to four definitions in advanced cancer patients.

methodsWe performed a prospective cohort study in 23 inpatient hospices/palliative care units in Japan. Advanced cancer patients aged ≥18 years who were admitted to inpatient hospices/palliative care units were included. The incidence and associated factors of sudden unexpected death were evaluated in all enrolled patients according to four definitions: (a) rapid decline death, defined as a sudden death preceded by functional decline over 1-2 days; (b) surprise death, defined if the primary responsible palliative care physician answered "yes" to the question, "Were you surprised by the timing of the death?"; (c) unexpected death, defined as a death that occurred earlier than the physicians had anticipated; and (d) performance status (PS)-defined sudden death, defined as a death that occurred within 1 week of functional status assessment with an Australia-modified Karnofsky PS ≥50.

resultsAmong 1896 patients, the incidence of rapid decline death was the highest (30-day cumulative incidence: 16.8%, 95% CI: 14.8-19.0%), followed by surprise death (9.6%, 8.1-11.4%), unexpected death (9.0%, 7.5-10.8%), and PS-defined sudden death (6.4%, 5.2-8.0%). Male sex, liver metastasis, dyspnea, malignant skin lesion, and fluid retention were significantly associated with the occurrence of sudden unexpected death.

conclusionSudden unexpected death is not uncommon even in inpatient hospices/palliative care units, with range of 6.4-16.8% according to the different definitions.
