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

Compromised placentation strongly predisposes to preeclampsia (PE) which is a severe complication of pregnancy. Pregnancy-associated plasma protein-A2 (PAPP-A2) has higher expression in the placenta than in any other tissues. However, the possible role of PAPP-A2 in placental development and in the pathogenesis of PE remains unclear. In this study, we aimed at exploring placental expression of PAPP-A2 in early- and late-onset of severe PE and its role in the mechanism inducing the development of PE. We found that expression of PAPP-A2 mRNA and protein was elevated in placentas from women with severe PE compared to control placentas and was localized to differentiated trophoblasts; higher in early-onset PE than that in late-onset PE. PAPP-A2 was expressed in the cytoplasm of both primary trophoblasts and HTR-8/SVneo cells. Elevated PAPP-A2 attenuated migration, invasion, explant outgrowth and network formation of trophoblast cells in vitro without affecting cell proliferation and apoptosis. PAPP-A2 attenuated trophoblast invasion and migration by restraining epithelial-mesenchymal translations via downregulation of the Hedgehog signaling pathway. Overall, the increased expression of placental PAPP-A2 is specific to different period of PE onset and PAPP-A2 may contribute to poor placentation and inadequate angiogenesis thereby leading to the development of preeclampsia.
