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
objectiveTo quantify the interplay between socioeconomic and ethnic inequalities in preterm birth rates in England from 2018 to 2021.
designA retrospective cohort study using electronic health data.
settingEnglish hospitals. POPULATION: 1537 595 women aged 13-55 with a singleton livebirth (April 2018-March 2021) at 24-42 gestational weeks were included.
methodsMultivariate Poisson regression was used to estimate the rate of preterm birth in each ethnic and deprivation group, adjusted rate ratios between groups, and associations. A post hoc calculation identified the rate of preterm birth for each ethnic group at each level of deprivation.
main outcome measuresPreterm birth (birth at less than 37 gestational weeks).
resultsThe rate of preterm birth was 6.30% (95% CI: 6.22-6.37) in women living in the most deprived areas, compared to a rate of 5.05% (95% CI: 4.96-5.14) among women in the least deprived areas. White women had a preterm birth rate of 5.74% (95% CI: 5.70-5.78), whereas South Asian and Black women had higher rates of preterm birth at 6.09% (95% CI: 5.98-6.21) and 5.89% (95% CI: 5.70-6.09), respectively. Deprivation interacted with ethnicity and attenuated the differences in the rate of preterm birth across all ethnicity groups (p < 0.001). In areas of high deprivation, preterm birth rates were similar across ethnicity groups, whereas in the least deprived areas, South Asian and Black women had higher rates.
conclusionDeprivation and ethnicity remain key drivers of inequalities in preterm birth. Prevention strategies need to address socioenvironmental and structural determinants of preterm birth in areas of high deprivation and minority ethnicity groups.
