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

objectiveTo examine inflammatory mediators in three fetomaternal biological compartments to inform theory related to the fetal and maternal inflammatory contributions to parturition at term and preterm.

methodsWe conducted a cross-sectional study of amniotic fluid, cord blood, and maternal plasma from women with singleton pregnancies. Women had one of four conditions: term labor (n=11), term not in labor (n=13), spontaneous preterm birth with intact membranes (preterm birth; n=13), or preterm prelabor rupture of membranes (PROM; n=8). We measured two damage-associated molecular pattern markers (high-mobility group box-1 [HMGB1] and uric acid) and two acute phase response markers (interleukin [IL]-6 and C-reactive protein [CRP]) using enzyme-linked immunosorbent assay. The distribution of each analyte within amniotic fluid, cord blood, and maternal plasma across the four conditions (term not in labor, term labor, preterm birth, and preterm PROM) were calculated. To explore whether there were distributional differences in each analyte across each of the four labor conditions, we used a nonparametric Kruskal-Wallis test. For analytes that differed across groups, we further compared distributions by labor group (term labor vs term not in labor, and preterm PROM vs preterm birth).

resultsFetal compartments (amniotic fluid and cord blood) showed higher HMGB1 in term labor vs term not in labor and preterm PROM vs preterm birth. Amniotic fluid IL-6, cord blood CRP and cord blood uric acid were higher in term vs term not in labor. Cord blood uric acid was higher in preterm PROM vs preterm birth. Only maternal plasma IL-6 was higher in term labor vs term not in labor.

conclusionAccumulation of HMGB1 and an overall increase in inflammation observed on the fetal side, but not the maternal side, may be signals of parturition. Understanding fetal-derived proparturition inflammatory signals at term and preterm, especially in preterm PROM, might provide fetal-specific biomarkers and identify underlying mechanisms and targets for interventions to reduce the risk of preterm birth and preterm PROM.
