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

backgroundMigrant women's overall increased risk of adverse pregnancy outcomes is well known. The aim of this study was to investigate possible associations between stillbirth and maternal country of birth and other migration related factors (paternal origin, reason for immigration, length of residence and birthplace of firstborn child) in migrant women in Norway.

methodsNationwide population-based study including births to primiparous and multiparous migrant women (n = 198,520) and non-migrant women (n = 1,156,444) in Norway between 1990 and 2013. Data from the Medical Birth Registry of Norway and Statistics Norway. Associations were investigated by multiple logistic regression and reported as odds ratios (ORs) with 95% confidence intervals (CIs).

resultsPrimiparous women from Sri-Lanka and Pakistan, and multiparous women from Pakistan, Somalia, the Philippines and Former Yugoslavia had higher odds of stillbirth when compared to non-migrant women (adjusted OR ranged from 1.58 to 1.79 in primiparous and 1.50 to 1.71 in multiparous women). Primiparous migrant women whose babies were registered with Norwegian-born fathers had decreased odds of stillbirth compared to migrant women whose babies were registered with foreign-born fathers (aOR = 0.73; CI 0.58-0.93). Primiparous women migrating for work or education had decreased odds of stillbirth compared to Nordic migrants (aOR = 0.58; CI 0.39-0.88). Multiparous migrant women who had given birth to their first child before arriving in Norway had higher odds of stillbirth in later births in Norway compared with multiparous migrant women who had their first child after arrival (aOR = 1.28; CI 1.06-1.55). Stillbirth was not associated with length of residence in Norway.

conclusionsThis study identifies sub-groups of migrant women who are at an increased risk of stillbirth, and highlights the need to improve care for them. More attention should be paid to women from certain countries, multiparous women who had their first baby before arrival and primiparous women whose babies have foreign-born fathers.
