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
Background: Postoperative delirium (POD) is a common complication after pediatric general anesthesia, impairing recovery. While vitamin D deficiency (VDD) is linked to POD in adults, its role in children remains unclear. This study investigates the association between preoperative 25-hydroxyvitamin D3 [25(OH)D3] levels and POD in children undergoing laparoscopic surgery under general anesthesia. Methods: This single-center retrospective study enrolled 320 pediatric patients. Demographic, surgical, anesthetic, and laboratory data were collected. Preoperative serum 25(OH)D3 was measured, and POD was assessed using the Cornell Assessment of Pediatric Delirium (CAPD) scale on postoperative days 1, 3, and 7. Meanwhile, patients were categorized into VDD (<30 ng/mL) and non-VDD (≥30 ng/mL) groups. Multivariable logistic regression identified independent risk factors for POD. Results: The incidence of POD was 80.3% (257/320) based on the CAPD score ≥9. POD patients had significantly lower serum 25(OH)D3 levels (P<0.05). In multivariable analysis, preoperative VDD was independently associated with a significantly higher risk of POD [adjusted odds ratio (OR) =14.25; 95% confidence interval (CI): 3.33-61.0; P<0.001]. A sensitivity analysis incorporating postoperative sleep quality [Children's Sleep Habits Questionnaire (CSHQ) score] confirmed the robustness of this association (OR =8.15; 95% CI: 1.88-35.3; P=0.005). The area under the receiver operating characteristic (ROC) curve for 25(OH)D3 in identifying POD was 0.613. Conclusions: Preoperative VDD is independently associated with a substantially increased risk of POD in pediatric patients undergoing general anesthesia for laparoscopic surgery. Preoperative screening for VDD may help identify at-risk children, and randomized controlled trials are warranted to evaluate whether preoperative vitamin D supplementation reduces POD incidence.
