Synthesis in Deutsches Arzteblatt international, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02174328 (Prevention of Preeclampsia With Aspirin Administered From the Beginning of Pregnancy in Recipients of Donated Oocytes.), which is not on this map. Cited by 20 papers, 6 of them syntheses that pooled it.

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.

Abstract

backgroundIn 2008 and 2009, the authors saw in their institution three women who had undergone oocyte donation and went on to develop severe de novo hypertension before the 26(th) week of gestation, with values above 180/110 mm Hg. Pregnancy was prematurely terminated in these cases because of the acute threat to the mother's life, and none of the three neonates survived. Five further cases with better outcomes were found to have occurred from 2006 to 2010. On the basis of this experience, the authors performed a meta-analysis to determine whether oocyte donation elevates the risk of pregnancy-induced hypertension (PIH). The cases are discussed in detail.

methodsSystematic review of the literature on PIH after oocyte donation, with meta-analysis and calculation of an odds ratio. We also provide a retrospective chart review of our own case series.

results28 publications were evaluated. The overall rate of PIH in a total of 2308 deliveries after oocyte donation was 22.6%. With the aid of data from 11 studies, the course of pregnancy in a total of 644 oocyte recipients was compared to that in a control group of 2320 women who were not oocyte recipients. The calculated odds ratio for PIH after oocyte donation, compared to conventional reproductive therapy, was 2.57 (95% CI, 1.91-3.47), while the calculated odds ratio for PIH after oocyte donation, compared to other women in the control group, was 6.60 (95% CI, 4.55-9.57).

conclusionThe data reveal that oocyte donation confers a considerable risk that the recipient will develop PIH. The very early and severe cases of preeclampsia that we report here are rather atypical; similar cases may have occurred elsewhere without finding their way into the relevant literature. The authors recommend close surveillance of pregnancies following allogenic oocyte transplantation by physicians with special expertise in prenatal medicine.
