Ethnic group, socioeconomic position and pregnancy outcome: a mediation model through latent class.

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
backgroundPreterm birth (PTB) and small-for-gestational-age (SGA) disproportionately affect women who are Black or Asian. Structural racism produces health inequalities. Identifying latent socioeconomic classes may help to understand the role socioeconomic position (SEP) plays in this inequality.
methodsWe included women from the baseline survey of the UK-based Millennium Cohort Study who had a live singleton pregnancy and gave birth from 1 September 2000 to 11 January 2002. Relative risks (RR) with 95% confidence intervals (CI) for PTB and SGA were estimated for ethnic groups compared with women who were white, with adjustment for SEP. Latent SEP classes were then identified using diverse prospective socioeconomic data. Mediation of health inequality via SEP and latent SEP class was tested.
resultsAmong 17 701 included women, 6.7% (95% CI 6.2%, 7.1%) experienced PTB and 7.0% (6.5%, 7.5%) SGA. We found evidence that the association between ethnic groups and PTB was mediated by latent SEP class for women who were Bangladeshi, Black African, Black Caribbean and Pakistani, with indirect 'effects' of RR 1.08 (1.01, 1.16), 1.07 (1.01, 1.14), 1.06 (1.00, 1.12) and 1.06 (1.00, 1.13), respectively, relative to White. When using the simple measures of maternal education, household income and marital status, we found no evidence of mediation except for a potential protective effect among Indian women, relative to White. We found similar evidence for SGA, with indirect effects through latent SEP class of RR 1.35 (1.19, 1.52), 1.32 (1.17, 1.48), 1.26 (1.12, 1.41), 1.27 (1.13, 1.42), respectively. When using the simple measures, we found evidence of mediation only among Black African and Black Caribbean women, with RR 1.16 (1.04, 1.30) and 1.12 (1.00, 1.26), respectively, relative to White.
conclusionThe determinants of inequality appeared to differ by ethnicity. We demonstrated the mediating role of individual-level SEP and a role for latent class analysis to interpret complex combinations of socioeconomic data.
