Evaluation of the SII and HALP scores in predicting perinatal outcomes in pregnancies with preterm premature rupture of membranes.

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
backgroundPreterm premature rupture of membranes (PPROM) is a leading cause of preterm birth and neonatal morbidity, with inflammation playing a key role in its pathogenesis. This study aimed to evaluate the predictive value of the Systemic Immune-Inflammation Index (SII) and the Hemoglobin-Albumin-Lymphocyte-Platelet (HALP) score for perinatal outcomes and delivery timing in pregnancies complicated by PPROM.
methodsThis retrospective cross-sectional study included 317 pregnant women who were diagnosed with PPROM between 24 and 36 + 6 weeks gestation, from January 2018 to January 2024. SII and HALP scores were calculated from blood parameters at admission using the following formulas: SII = [platelets(/L) × neutrophils(/L)] / lymphocytes(/L) and HALP = [hemoglobin(g/L) × albumin(g/L) × lymphocytes(/L)] / platelets(/L). Neonatal outcomes (birth weight, APGAR scores, NICU admission) and delivery timing were analyzed. ROC curves and logistic regression models were used to assess predictive performance.
resultsHigher SII values were significantly associated with lower birth weights, lower 1- and 5-minute APGAR scores, and increased NICU admission. The SII showed modest predictive power for NICU admission (AUC: 0.653, cut-off = 1145.75) and strong discriminative ability for predicting delivery within 7 days (AUC: 0.860, cut-off: 1421, sensitivity and specificity: 78%). In contrast, the HALP showed limited and inconsistent discriminative performance and was not significantly associated with adverse outcomes. Multivariate logistic regression confirmed that the SII was as an independent predictor of NICU admission (p = 0.012).
conclusionThe SII is a promising biomarker for predicting adverse neonatal outcomes and the timing of delivery in PPROM patients. A SII value > 1421 may indicate delivery within 7 days, aiding in clinical management. Each 100-unit increase in SII was associated with an increased risk of NICU admission. The HALP score was not a reliable predictor.
