Detecting the preoperative peripheral blood systemic immune-inflammation index (SII) as a tool for early diagnosis and prognosis of gallbladder cancer.

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
objectiveEvidence indicates that the systemic immune-inflammation index (SII) correlates with poor prognosis in various solid tumors. This retrospective study aimed to evaluate the diagnostic and prognostic significance of preoperative SII combined with tumor markers for early detection and prognosis of gallbladder cancer (GBC).
methodsPreoperative SII levels and serum tumor markers [carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), and carbohydrate antigen 19 - 9 (CA19-9)] were measured in GBC patients. Correlations and diagnostic efficacy were analyzed using Spearman correlation and receiver operating characteristic (ROC) curve analyses. The relationship between SII and clinical data was analyzed, and cumulative survival rates of the two groups were compared. Independent risk factors for poor prognosis in GBC patients were assessed using Kaplan-Meier curves and Cox multivariate analysis.
resultsPreoperative SII, CEA, CA125, and CA19-9 levels were significantly elevated in GBC patients compared to those with benign lesions. SII positively correlated with CEA, CA125, and CA19-9 levels (r = 0.434, 0.570, 0.614, respectively, all P < 0.001). The area under the ROC curve (AUC) for the combination of SII, CEA, CA125, and CA19-9 was 0.877 for early GBC diagnosis and 0.923 for predicting postoperative mortality, outperforming each marker individually. An SII threshold > 889.52 was predictive of postoperative death. High SII was associated with tumor size, differentiation, tumor-node-metastasis stage, lymph node metastasis, perineural invasion, surgical type, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and serum tumor marker levels. Kaplan-Meier analysis revealed poorer survival in the high SII group. Preoperative SII was identified as an IRF for poor prognosis in GBC patients.
conclusionPreoperative SII correlates strongly with CEA, CA125, and CA19-9 levels. The combined use of SII and tumor markers offers high diagnostic value for early GBC detection and robust predictive value for postoperative mortality. Preoperative SII serves as an IRF for poor prognosis in GBC patients.
