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

Serum albumin levels are inversely related with oxidative stress, but positively related with endothelial function, in pregnant women. However, it is unclear whether hypoalbuminemia in pregnant women with preeclampsia (PE) increases the production of oxygen-derived free radicals and impacts endothelial function. The present study aimed to assess the relationship between serum albumin, oxidative stress, and endothelial dysfunction in pregnant women with PE. A total of 75 women with control pregnancy (Control group, n = 30), PE (PE group, n = 24), or gestational hypertension (GH) (GH group, n = 21) were enrolled. We assessed serum albumin levels, diacron-reactive oxygen metabolites (d-ROMs) as an oxygen-derived free radical marker, and flow-mediated dilation (FMD) as a readout for vascular endothelial function during the gestational period and at one month after delivery. During the gestational period, FMD was lower, but d-ROM levels were higher, in the PE and GH groups compared with the Control group. Serum albumin levels were lower in the PE group compared with the Control and GH groups. d-ROM levels were inversely correlated with serum albumin levels (r = -0.54, p < 0.05) and FMD (r = -0.56, p < 0.05) in the PE group, and negatively correlated with FMD, but not serum albumin levels, in the GH group. Serum levels of d-ROMs and albumin, as well as FMD, were similar between groups after delivery. Our findings suggest that reduced serum albumin levels enhance the production of oxygen-derived free radicals, resulting in impaired maternal vascular endothelial function in parturients with PE.
