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
Objective: To systematically evaluate the effectiveness of indocyanine green (ICG) fluorescence navigation in visualizing extrahepatic bile ducts during laparoscopic cholecystectomy, and to identify factors influencing imaging quality. Methods: A total of 217 patients who underwent ICG fluorescence-guided laparoscopic cholecystectomy at Chaoyang Central Hospital between January and August 2025 were prospectively included. The visualization of the cystic duct (CD), right hepatic duct (RHD), common hepatic duct (CHD), and common bile duct (CBD) was assessed at three stages: before Calot's triangle dissection, after dissection, and after gallbladder removal. Clinical factors potentially affecting visualization quality were analyzed. Results: One case of a RHD anatomical variation accompanied by intraoperative bile leakage was identified. Before Calot's triangle dissection, the CBD demonstrated the highest visualization rate (73.7%), whereas the RHD showed the lowest (15.2%). After dissection, visualization rates of the CD, CHD, and CBD all exceeded 90%, while 31.8% of the RHD remained inadequately visualized. Multivariate analysis revealed that unsatisfactory CD visualization was independently associated with inflammation (OR = 2.852, 95% CI: 1.496-5.435) and surgical type (OR = 9.528, 95% CI: 1.140-79.609); unsatisfactory RHD visualization correlated with tissue adhesion (OR = 26.913, 95% CI: 10.352-69.971); suboptimal CHD visualization was associated with inflammation (OR = 2.765, 95% CI: 1.470-5.200); and inadequate CBD visualization was also linked to inflammation (OR = 2.472, 95% CI: 1.234-4.951). Conclusion: ICG fluorescence navigation facilitates real-time visualization of extrahepatic bile ducts during laparoscopic cholecystectomy, with inflammation identified as a key factor affecting visualization quality.
