Structural and individualized racism drives racial disparities in chronic low back pain: A cross-sectional serial mediation analysis.

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
This cross-sectional study examined whether individualized racism, as measured by experiences of discrimination, internalized stigma of chronic pain, and perceived injustice, as well as structural racism, as measured by the Area Deprivation Index (ADI), mediates racial disparities in nonspecific chronic low back pain (CLBP) outcomes among non-Hispanic Blacks (NHBs) and non-Hispanic Whites (NHWs). 258 adults completed questionnaires assessing pain severity, pain interference, discrimination, internalized stigma, and perceived injustice. The mean pain severity and pain interference scores were 61.59 (SD = 19.98) and 47.46 (SD = 29.17), respectively. Serial mediation analysis, adjusting for age and sex, revealed that discrimination and internalized stigma mediated the association of race with pain severity and interference, with significant indirect effects: β = -1.357, 95% CI [ -2.557, -0.367] and β = -2.576, 95% CI [ -4.657, -0.721], respectively. Serial mediation analysis also revealed that discrimination and perceived injustice mediated the association of race with pain severity and pain interference, with significant indirect effects: β = -1.519, 95% CI [ -2.932, -0.400] and β = -2.804, 95% CI [ -5.330, -0.809], respectively. ADI also significantly mediated the indirect effects of race on pain severity (β = -3.138, 95% CI [-5.646, -0.962]) and pain interference (β = -4.238, 95% CI [-8.123, -1.067]). Thus, racial disparities in CLBP severity and interference may be explained by multilevel mechanisms: an individual's race is linked to discrimination, which predicts internalized stigma and perceived injustice; these factors, in turn, predict CLBP outcomes; and race also correlates with ADI, which in turn correlates with CLBP outcomes. PERSPECTIVES: Racial pain disparities are well documented. These findings suggest that intrapersonal (internalized stigma of chronic pain), interpersonal (experiences of discrimination and perceived injustice) and structural (neighborhood deprivation) racism-related factors indirectly mediate the relationship between race and chronic low back pain outcomes.
