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
This study compared the clinical outcomes and diagnostic accuracy of Fluorescence-guided laparoscopic lymph node biopsy (FGLLB) with conventional laparoscopic lymph node biopsy (LLB) at a single institution. We compared 42 patients who underwent FGLLB between April 2022 and September 2025 with a historical group of 55 LLB patients. The main outcomes measured were surgical time, blood loss, surgical conversion rates, hospital stay, and morbidity. Diagnostic accuracy was the secondary outcome. Surgical conversion occurred in one FGLLB patient (2.3%) and two LLB patients (3.6%) due to surgical difficulties. Surgical time was shorter in the FGLLB group (67.5 ± 33.7 min) compared to the LLB group (83 ± 22.2 min), though this difference was not statistically significant (p = 0.093). The average hospital stay was also shorter for FGLLB patients (1.6 days) compared to LLB patients (2.2 days), a difference that nearly reached statistical significance (p = 0.073). Minor postoperative complications were observed in two FGLLB patients and one LLB patient (4.7% vs 1.8%, p = 0.411). The biopsy provided the necessary diagnostic information in 97.6% of FGLLB cases and 96.3% of LLB cases. FGLLB showed good procedural and postoperative outcomes and a high diagnostic yield, comparable to traditional LLB. FGLLB was associated with shorter surgical times and hospital stays. The fluorescence guidance makes dissection more precise and safer by targeting a visible structure, which helps avoid unnecessary dissection and may contribute to the reduced surgical duration. More research is needed to confirm the reliability of this technique before it is widely adopted.
