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

objectivesTo determine the prevalence of neuropathic pain among terminally ill patients with cancer admitted to a general ward, using the International Association for the Study of Pain algorithm.

methodsThis prospective observational study was conducted at a tertiary care center. We enrolled terminally ill patients with cancer admitted to the general ward between September 2018 and September 2019. On the day of consultation with our palliative care team, pain management clinicians examined and diagnosed neuropathic pain using the International Association for the Study of Pain diagnostic criteria.

resultsA total of 108 patients were enrolled during the study period. The median age was 69 years (interquartile range [IQR] 58.3-76.8 years), 72 patients (66.7%) were men, and the median survival time was 33 days (IQR 14.3-62 days). Of the 108 patients, 33 (30.6%) had neuropathic pain. Patients with neuropathic pain had more severe pain than those without neuropathic pain.

conclusionsThe prevalence of neuropathic pain in terminally ill patients with cancer admitted to a Japanese general ward was 30.6%. Further studies are warranted to elucidate whether the accurate diagnosis of neuropathic pain can improve pain control and/or patient conditions.
