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

Background: Villitis of unknown etiology (VUE) is a chronic placental inflammatory lesion of high incidence, but its relationship with adverse pregnancy outcomes remains unclear. This meta-analysis quantifies its impact on five critical complications adverse pregnancy outcomes, including fetal growth restriction (IUGR), preeclampsia (PE), gestational hypertension, small gestation age (SGA), and stillbirth. Methods: We used the search verb "villitis of unknown etiology" OR "VUE" OR "chronic villitis" OR "unknown etiology of villitis", from databases SCOUP, PubMed and Google Scholar, incorporating cohort studies, case-control studies. Heterogeneity was assessed via Results: The incidence of VUE was higher in the IUGR, PE, gestational hypertension, SGA, and stillbirth groups than in the normal control group. VUE was significantly associated with an increased risk of stillbirth (OR = 3.64, 95% CI: 1.80-7.39) and pre-eclampsia (OR = 1.31, 95% CI: 1.03-1.65). A marginal association was observed between VUE and gestational hypertension (OR = 1.41, 95% CI: 0.892-2.23). In contrast, the associations of VUE with IUGR (OR = 1.56, 95% CI: 0.509-4.77) and SGA (OR = 1.01, 95% CI: 0.099-10.4) were not statistically significant and exhibited substantial heterogeneity. Conclusion: VUE is strongly associated with stillbirth and PE, highlighting its role in the pathogenesis of placental-related diseases. While there are no significant associations were found with intrauterine growth restriction or small for gestational age infants based on current evidence, these findings solidify the link between VUE and specific obstetric syndromes.
