Serum heat shock protein 90 alpha levels in mild and severe preeclampsia.

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
objectiveThe aim of the study was to assess serum heat shock protein 90 alpha levels as a marker in preeclampsia.
methodsThis cross-sectional study was carried out in 2015 at Istanbul Cerrahpasa University, University Hospital for Obstetrics and Gynecology. The mild (n=60) and severe (n=60) preeclampsia groups were compared with healhty, uncomplicated pregnancies, matched for gestational age within ±1 week (n=120). The main inclusion criteria were women between 18 and 40 years old who had a singleton pregnancy. Pregnant women with any known medical diseases (chronic hypertension, renal diseases, inflammatory diseases, or infections), regular contractions with cervical changes, and premature rupture of membranes were excluded from the study.
resultsMedian serum heat shock protein 90 alpha was significantly elevated in mild preeclamptic women compared to women in the gestational age-matched control group [3.41 vs. 2.62 ng/mL, p<0.001]. The mean serum heat shock protein 90 alpha levels were significantly elevated in the severe preeclampsia group compared to their gestational age-matched control group [3.94 vs. 2.55 ng/mL, p<0.001]. Mean serum heat shock protein 90 alpha levels were comparable between the mild and severe preeclampsia groups (3.41 vs. 3.94 ng/mL, p=0.407) and mild early-onset and severe early-onset groups (p=0.104). Serum heat shock protein 90 alpha showed a weak positive correlation with both systolic and diastolic arterial blood pressure.
conclusionHeat shock protein 90 alpha level was elevated in preeclamptic patients. The level of heat shock protein 90 alpha in serum may be suitable for evaluating endothelial dysfunction.
