Association Between Perioperative Inflammatory Trajectories and Postoperative Hirschsprung-Associated Enterocolitis: Insights from Group-Based Trajectory Modeling.
Article in Journal of inflammation research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: This retrospective cohort study aimed to delineate the dynamic change trajectories of perioperative inflammatory markers in pediatric patients with Hirschsprung disease (HSCR) who underwent one-stage laparoscopic-assisted pull-through surgery at a single tertiary pediatric center using Group-Based Trajectory Modeling (GBTM), and to explore the association between different trajectory patterns and the risk of postoperative Hirschsprung-associated enterocolitis (HAEC). Methods: This study enrolled HSCR patients who underwent surgical treatment. Blood samples were collected at four perioperative time points (preoperative, postoperative days 1, 4, and 7) to calculate composite inflammatory markers such as the systemic inflammation response index (SIRI) and pan-immune inflammation value (PIV), as well as individual markers like white blood cell (WBC) and neutrophil counts. GBTM was employed to identify subgroups with similar inflammatory marker change trajectories. Multivariable logistic regression analysis was used to assess the association between different inflammatory trajectories and postoperative HAEC occurring within several years after surgery. Results: A total of 400 patients were included, of which 133 (33.3%) developed postoperative HAEC. Each inflammatory marker was categorized into 2-3 significantly distinct trajectory groups via GBTM. Multivariable logistic regression analysis revealed that for SIRI and PIV, compared to trajectory group 1 (low baseline with mild rise), patients in trajectory group 2 (moderate baseline with sharp rise and slow decline; SIRI: OR = 5.20, P = 0.011; PIV: OR = 4.75, P = 0.007) and trajectory group 3 (high baseline with sharp rise and slow decline; SIRI: OR = 4.73, P = 0.025; PIV: OR = 5.63, P = 0.008) had a significantly increased risk of postoperative HAEC. For WBC and neutrophils, trajectory group 2 (WBC: persistently high; neutrophils: low baseline with sharp rise and rapid decline) was an independent risk factor for postoperative HAEC (WBC: OR = 2.49, P = 0.004; neutrophils: OR = 2.53, P = 0.001). Conclusion: Specific rising trajectories of SIRI, PIV, WBC, and neutrophils may serve as novel biomarkers for early identification of children at high risk for HAEC.
