Epidemiology of Pain Among Patients with Solid Metastatic Cancer During the Last Year of Life.
Article in Journal of pain research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Background: Despite medical advancements, pain is a major source of suffering at the end of life for patients with a solid metastatic cancer. We aimed to assess the trajectory of pain prevalence, severity, interference, and inadequacy of analgesia during the last year of life. Methods: We analysed data from the last year of life of 345 decedents from a prospective cohort study of 600 patients with a solid metastatic cancer in Singapore. Patients were surveyed every 3 months and their pain outcomes (prevalence, severity, and interference) and inadequacy of analgesia were analysed. We used mixed-effects regressions to assess the association of pain outcomes with patients' time from death, demographics, and planned or unplanned hospitalisations. Results: Prevalence of pain was higher in the last 2 months (65%) compared to 11 to 12 months (41%) before death. Pain severity and interference scores (mean ± SD) were also higher in the last month (severity: 2.5±2.6; interference: 2.6±3.0) compared to 12 months before death (severity: 1.4±2.0; interference: 1.4±2.0). At any time during the last year of life, 38% of the patients were prescribed non-steroidal anti-inflammatory drugs, 11% were prescribed weak-opioids and 29% were prescribed strong opioids. These analgesics were prescribed through either oral, topical or injectable route. Pain outcomes were significantly worse (p-value<0.05) for younger patients, those with higher education, and more financial difficulties, while interference was higher after an unplanned hospitalisation in the last month. Females reported higher pain severity score during their last year of life compared to males. For patients reporting moderate to severe pain, inadequacy of analgesia was lower in the last 2 months (43%) compared to 11 to 12 months before death (83%). Conclusion: Findings highlight the need for greater attention in monitoring and treatment of pain even earlier in the disease trajectory, and increased attention to patients discharged from an unplanned hospitalisation.
