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: Acute kidney injury (AKI) is a serious complication in patients with neonatal jaundice, and inflammation is key to its development. The systemic immune-inflammation index (SII) has been associated with AKI in adults, but its role in jaundiced neonates is unknown. This study aimed to assess the association between SII and AKI risk in this population. Methods: This retrospective study utilized data from the Medical Information Mart for Intensive Care-IV database, including 2,326 patients with neonatal jaundice. Due to skewed SII distribution, log2-transformed SII (logSII) was used. Logistic regression was used to analyze the logSII-AKI association. Restricted cubic spline (RCS) analysis was used to explore the nonlinear relationship. Subgroup and interaction analyses were conducted to assess the sensitivity of the relationship across clinical characteristics. Complete-case analysis and the E-value were used to assess the robustness of the association. The correlation between logSII and neonatal intensive care unit (NICU) duration was examined using Spearman correlation analysis. Results: Higher logSII was independently associated with increased AKI risk {adjusted odds ratio (OR) [95% confidence interval (CI)]: 1.230 (1.107, 1.369); P<0.001}. RCS analysis showed no significant departure from linearity (P for overall <0.001, P for non-linear =0.51), which remained robust after adjustment. The association was generally consistent across predefined subgroups (all P for interaction >0.05). The findings were robust in sensitivity analyses [E-value =1.76 for the point estimate; multiple imputation for bilirubin: OR 1.227 (1.105, 1.364); complete-case analysis: OR 1.256 (1.103, 1.431)]. Interestingly, higher logSII correlated with shorter NICU duration (Spearman r=-0.174, P<0.001). Conclusions: logSII demonstrates an independent, approximately linear association with AKI risk in jaundiced neonates. The paradoxical association with NICU duration warrants further investigation.
