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

Few studies have assessed the risk of adverse pregnancy outcomes in women with multiple sclerosis (MS). We used 2 large US administrative databases, the Truven Health MarketScan Database (2011-2015; Truven Health Analytics Inc., Ann Arbor, Michigan) and the Nationwide Inpatient Sample (2007-2011), to identify delivery cohorts. MS and pregnancy outcomes (infections, cesarean delivery, preterm delivery, poor fetal growth, preeclampsia, chorioamnionitis, postpartum hemorrhage, stillbirth, and infant malformations) were identified during pregnancy and at delivery. We calculated adjusted risk ratios according to MS status and relapse(s) in the year before delivery. Among over 5 million pregnancies, we identified 3,875 pregnancies in women with MS. Women with MS had an increased risk of infections during pregnancy (Truven Health: adjusted risk ratio (aRR) = 1.22, 95% confidence interval (CI): 1.16, 1.27) and preterm delivery (Truven Health: aRR = 1.19 (95% CI: 1.04, 1.35); Nationwide Inpatient Sample: aRR = 1.30 (95% CI: 1.16, 1.44)). The risks of other outcomes were similar for women with and without MS. In the Truven Health database, risk ratios for the pregnancy outcomes in women experiencing relapses versus those without relapses were between 0.9 and 1.4, and confidence intervals overlapped the null. Overall, women with MS had an increased risk of infections and preterm delivery; however, their risks for other adverse pregnancy outcomes were not elevated. Disease activity before delivery was not a strong predictor of outcomes.
