Modifiable pathways from pain to functional status: Confirmatory baseline results from a randomised trial of African American patients with cancer pain.
Trial report in European journal of cancer care, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveThis study tested a model of cancer-related pain and functional status in African American patients, including beliefs about the ability to control pain as a key determinant of distress and functional status.
methodsBaseline data from a randomised clinical trial consisting of clinical and patient-reported outcomes were used. Participants were 228 African American patients experiencing moderate to severe pain within the past 2 weeks. The model comprised four latent constructs: pain, perceived control over pain, pain-related distress and functional status. Confirmatory factor analysis was used to validate the factor structure of the measurement model. Structural equation modelling was used to estimate direct and mediated effects.
resultsThe measurement model fit well (RMSEA = 0.06, SRMR = 0.05) with all loadings significant (p < 0.05). The structural model also fit well (RMSEA = 0.04, SRMR = 0.05). The complex mediated pathway from pain to functional status through perceived control over pain and pain-related distress was strong and significant (specific indirect effect = -0.456, p = 0.004). Mediation by perceived control accounted for a 47% reduction of the effects of pain on functional status.
conclusionIf these results hold up longitudinally, interventions to increase perceived control over pain have the potential to improve functional status by decreasing pain-related distress.
