Characteristics of moderate-to-severe chronic pain and its association with daily functional impairment among older outpatients in Vietnam.
Article in PloS one, 2025. 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
OBJECTIVE(S): To describe the characteristics of moderate-to-severe chronic pain, and its association with daily functional decline among older individuals attending a large outpatient geriatric clinic in Hanoi, Vietnam.
methodsA cross-sectional study was undertaken between November, 2019 and March, 2020. In-person structured interviews were conducted in 518 patients 60 years and older with chronic pain. Patient's self-reported pain was categorised into two levels of mild (0-3), moderate to severe (4-10) pain based on a 0-10 scale.
resultsThe median age of the study sample was 69 years, women accounted for 74.1%. The knee-foot-leg region was the most common site of chronic pain in both groups (39.5% in mild pain vs. 45.1% in moderate-to-severe pain. Participants experiencing moderate-to-severe pain were more likely to describe their pain as dull (65.5%) or burning (11.3%) and to report pain occurring independently of specific activities (48.7%), compared to those with mild pain (53.9%, 1.2%, and 32.4%, respectively). In a multivariable adjusted model, dependency in activities of daily living (OR: 3.73, 95% CI: 1.82-7.68) and dependency in instrumental activities of daily living (OR: 9.41, 95% CI: 3.94-22.5) were significantly associated with moderate-to-severe pain.
conclusionsModerate to severe chronic pain was reported in a high proportion of older Vietnamese outpatients and was associated with impaired daily functional impairment.
