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
objectiveThe aim of this study was to investigate the clinical, imaging, and hematological parameters predicting the necessity of surgical intervention in pregnant women presenting with symptomatic gestational hydronephrosis.
methodsWe retrospectively evaluated 192 pregnant women diagnosed with symptomatic hydronephrosis between January 2015 and September 2024. Patients were divided into Group 1 (conservative management, n=138) and Group 2 (surgical intervention via double-J stent or percutaneous nephrostomy, n=54). Demographic data, clinical findings, degree of hydronephrosis, urinalysis, and complete blood count parameters-including C-reactive protein, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index-were compared. Logistic regression analysis was performed to identify predictors for surgery.
resultsA history of urolithiasis, prolonged pain, fever, severe hydronephrosis, pyuria, and elevated creatinine were significantly higher in Group 2 (p<0.05). White blood cell, neutrophil-to-lymphocyte ratio, and C-reactive protein levels did not differ significantly between the groups. However, platelet counts (p=0.020), platelet-to-lymphocyte ratio (p=0.038), and systemic immune-inflammation index (p=0.015) were significantly elevated in the surgical cohort. Univariate logistic regression analysis revealed that an elevated platelet count (p=0.039) and a higher systemic immune-inflammation index (p=0.004) were significant predictors. In the multivariate analysis, the systemic immune-inflammation index remained an independent predictor (p=0.009), whereas platelet count did not.
conclusionWhile clinical presentation and the severity of hydronephrosis primarily indicate the need for surgical intervention, the systemic immune-inflammation index serves as a valuable, cost-effective auxiliary predictor among the hematological parameters.
