1 · What the graph read from it

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.

2 · The registry

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 estimate socio-economic (SES) inequalities in stillbirth and preterm birth rates across European countries using population-based routine data.

designCross-sectional study of national-level perinatal health and SES indicators (mother's education/occupation or area-level deprivation).

settingTwenty-four countries in the Euro-Peristat network. POPULATION: Seventeen million births in 2015-2019.

methodsRates of stillbirth, singleton very preterm birth (VPB) and singleton moderate/late preterm birth (MLPB) were derived from routine national birth data collected with a common protocol.

main outcome measurePercentage of excess adverse outcomes associated with SES and concentration indices.

resultsMedian rates of adverse outcomes were higher in the lowest versus highest SES groups [Stillbirth: 4.9 (interquartile range (IQR):4.30-5.80)] versus 2.7 (IQR:2.25-3.14) per 1000 births; VPB: 1.0 (IQR: 0.87-1.12) versus 0.6 (IQR: 0.59-0.66) per 100 live births; MLPB: 5.8 (IQR: 5.27-6.40) versus 4.4 (IQR:4.13-4.65) per 100 live births. Excess adverse outcomes associated with lower SES varied greatly, particularly for stillbirth (range-3%, 51%) versus VPB (7%, 27%) and MLPB (5%, 20%). Concentration indices further highlighted varying socio-economic inequalities across countries. Median concentration indices were similar for countries with both lower and higher levels of adverse events, with median CIs of -0.12 for countries with both high and low levels of stillbirth.

conclusionWe identified widespread but varying inequalities between countries. These seemed to be unrelated to the rate of adverse outcomes. This suggests the need for policy strategies directly targeted to the prevention of stillbirth and preterm birth in low SES populations. Our findings demonstrate the feasibility of monitoring inequalities internationally using routine data to identify effective action.
