The sFlt-1 to PlGF ratio in pregnant women with rheumatoid arthritis: impact of disease activity and sulfasalazine use.

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.
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
objectivesAn elevated sFlt-1/PlGF ratio has been validated as a significant predictor of preeclampsia, but has not been established in women with RA. We explored whether the sFlt-1/PlGFratio could be altered due to disease activity in RA, and could be applied in this population to predict preeclampsia. Since SSZ has been suggested to improve the angiogenic imbalance in preeclampsia, we also aimed to examine whether SSZ could affect sFlt-1 or PlGF levels.
methodsMaking use of a nationwide, observational, prospective cohort study on pregnant women with RA, sFlt-1 and PlGF were measured in the third trimester. A total of 221 women, aged 21-42 years, were included, with a median gestational age of 30 + 3 weeks.
resultsNo differences in sFlt-1 or PlGF were observed between women with high, intermediate or low disease activity (P = 0.07 and P = 0.41), whereas sFlt-1 and PlGF did not correlate with DAS28-CRP score (r = -0.01 and r = -0.05, respectively). Four (2%) women with a sFlt-1/PlGF ratio ≤38 developed preeclampsia in comparison to three (43%) women with a ratio > 38, corresponding to a negative predictive value of 98.1%. SSZ users (n = 57) did not show altered levels of sFlt-1 or PlGF in comparison to non-SSZ users (n = 164, P = 0.91 and P = 0.11).
conclusionOur study shows that in pregnant women with RA, the sFlt-1/PlGF ratio is not altered due to disease activity and a cut-off ≤38 can be used to exclude preeclampsia. Additionally, SSZ use did not affect sFlt-1 or PlGF levels in this population.
