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

purposeThe aim of our study was to investigate selected pre-eclampsia (PE)-related miRNAs in clearly defined early- and late-onset PE (eoPE, loPE) cohorts and compare them with healthy controls.

methodsThis is a single-center, pilot study comparing pregnancies with eoPE (n=10) and loPE (n=8), each with separate healthy controls (n=10; n=8). Serum miRNA (miR-) expression levels of selected PE-associated miRNAs (miR-210-3p, miR-518b) were quantified by real-time PCR.

resultsSimilar expression profiles (delta CT ± standard deviation) were observed between loPE vs. controls: miR-210-3p (8.20 ± 1 vs. 7.48 ± 1.2; p=0.16; Hodges-Lehmann estimator (HL): - 0.73, 95% confidence interval (CI) - 2.2 to 0.78) and miR-518b (9.82 ± 1.1 vs. 9.60 ± 0.9; p=0.80, HL: - 0.14, 95% CI - 1.61 to 0.91). Comparing eoPE cases to controls, we found an increase of miR-210-3p concentration (7.63 ± 1.1 vs. 9.31 ± 1.9; p=0.019; HL: 1.23, 95% CI 0.15 to 2.66, mean fold change: 3.2; sensitivity analysis: p=0.067) and a numerical difference in miR-518b expression without reaching statistical significance (8.77 ± 1.4 vs. 9.85 ± 1.8; p=0.19; HL: 0.70, 95% CI - 0.33 to 2.41; mean fold change: 2.1).

conclusionIn the eoPE, miR-210-3p levels were higher than in controls, with the same trend observed in the sensitivity analysis, although statistical significance was no longer reached (p=0.067). miR-518b showed a numerical, non-significant difference between eoPE and controls. No significant differences were observed in loPE. Given the small sample size and overlap with early-onset fetal growth restriction, these findings should be considered exploratory.
