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: Complete transperitoneal nephroureterectomy (CTNU) in a single-position is an advanced surgical technique for the treatment of upper urinary tract urothelial carcinoma (UTUC), performed entirely through a transperitoneal approach without the need for patient repositioning. Indocyanine green (ICG) has been extensively studied in urologic surgery, with applications ranging from sentinel lymph node mapping to tumor localization. This study aimed to evaluate the performance of retrograde ureteral fluorescence imaging in CTNU. Methods: This retrospective cohort enrolled 81 patients diagnosed with UTUC and underwent single-position CTNU. Cohorts were divided into two groups according to whether the ICG was applied. Perioperative data and oncology outcomes were recorded and analyzed. Results: In total, 81 eligible participants were finally included, with 40 in the ICG group and 41 in the non-ICG group. The ICG group presented significantly shorter ureter identification time (8.5±3.3 Conclusions: ICG guided ureteral fluorescence imaging in single-position CTNU showed significant advantages in precisely and effectively locating the ureter, with improved surgical outcomes. Meanwhile, the enhanced visualization of the ureteral intramural segment and bladder cuff facilitated the complete removal of the specimen en bloc and the watertight closure of the bladder.
