Systemic immune-inflammation index predicts acute histologic chorioamnionitis pathologic staging and neonatal respiratory distress syndrome in women with preterm premature rupture of membranes: a retrospective cohort study.
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundWe aimed to investigate the predictive value of the systemic immune-inflammation index (SII) for acute histologic chorioamnionitis (HCA) pathologic staging and neonatal respiratory distress syndrome (NRDS) in women with preterm premature rupture of membranes (PPROM).
methodsWe retrospectively evaluated 135 pregnant women with PPROM at a gestational age of 20+ 0 ~ 33+ 6 weeks. The women based on placental histopathology were categorized into No/Mild and Moderate-Severe group. Multivariate logistic regression analysis was conducted to assess the factors influencing Moderate-Severe HCA and to develop a nomogram model. The model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curves.
resultsOf the 135 women, 63 were included in the No/Mild HCA group and 72 were included in the Moderate-Severe HCA group. Among inflammatory markers, the SII showed the highest area under the curve (AUC) for predicting Moderate-Severe HCA. The Moderate-Severe HCA group displayed lower gestational age at PPROM, lower birth weight and higher SII compared with the No/Mild HCA group. Multivariate logistic regression analysis identified SII, C-reactive protein (CRP) and gestational age at PPROM as independent prognostic factors affecting Moderate-Severe HCA, our nomogram model incorporating these three factors had the highest AUC of 0.853 (95%CI: 0.788–0.918), followed by gestational age at PPROM, CRP and SII with AUCs of 0.786 (95%CI: 0.705–0.764), 0.697 (95%CI: 0.619–0.776) and 0.674 (95%CI: 0.584–0.764), respectively. The sensitivity and specificity of the nomogram model, gestational age at PPROM, CRP, and SII were 0.708 and 0.889, 0.681 and 0.714, 0.653 and 0.905, 0.583 and 0.667, respectively. The model showed well-fitted calibration curves and the clinical benefit. The model and birth weight are independent risk factors affecting NRDS.
conclusionsSII was identified as an inflammatory biomarker in both Moderate-Severe HCA and NRDS can serve as a useful tool to guide clinical treatment decisions.
