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

introductionThis study was conducted to evaluate soluble Toll-like receptor 2 (sTLR-2) and soluble Toll-like receptor 4 (sTLR-4) levels in vaginally obtained amniotic fluid and investigate their value in the prediction of histological chorioamnionitis (HCA). MATERIAL AND

methodsThis prospective case-control study included patients who had been diagnosed with preterm premature rupture of membranes before 34 weeks of gestation and were admitted to Vilnius University Hospital Santaros Klinikos. Free leaking amniotic fluid was obtained vaginally using a sterile speculum up to 48 h before delivery. Amniotic fluid levels of sTLR-2 and sTLR-4 were determined using an enzyme-linked immunosorbent assay. The diagnosis of chorioamnionitis was confirmed by histological examination of the placenta and membranes after delivery.

resultsThe study included 156 patients, 65 with (HCA Group) and 91 without (non-HCA Group) HCA. No statistically significant differences were noted in the concentrations of sTLR-2 and sTLR-4 in vaginally obtained amniotic fluid between patients with and without HCA: the median sTLR-2 level was 0.09 ng/mL in the HCA Group vs 0.1 ng/mL in non-HCA Group, and the median sTLR-4 level was 0.23 ng/mL in the HCA Group vs 0.28 ng/mL in non-HCA Group (p > 0.05). A positive correlation between sTLR-2 and sTLR-4 levels was identified (ρ = 0.57, p < 0.001), but no correlation was found between these markers and gestational age.

conclusionsConcentrations of sTLR-2 and sTLR-4 in vaginally obtained amniotic fluid do not reflect the presence of HCA in pregnancies complicated by preterm premature rupture of membranes before 34 weeks of gestation.
