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
backgroundNeoadjuvant chemoradiotherapy (nCRT) is key for low rectal cancer but raises the risk of anastomotic leakage (AL). This study examines how fluorescence laparoscopic (FL) surgery reduces AL after intersphincteric resection (ISR), especially in nCRT patients.
methodsThis real-world multicenter cohort study included 533 patients undergoing laparoscopic ISR for ultra-low rectal adenocarcinoma from January 2012 to July 2023. Patients were categorized into FL and non-FL groups. Propensity score matching (PSM) was used at a 1:2 ratio to adjust for baseline differences. The primary endpoint was the incidence of AL within 6 months postoperatively. Secondary endpoints included anastomotic site perfusion, intraoperative blood loss, lymph node retrieval, perioperative complications, and postoperative recovery metrics. Subgroup analyses were conducted on the basis of nCRT status.
resultsAfter PSM, 393 patients were analyzed (131 FL versus 262 non-FL). The FL group showed a significantly lower AL incidence (3.1% versus 11.5%, P = 0.005), with fewer severe symptomatic AL cases (0.8% versus 6.1%, P = 0.014). Intraoperative blood loss was reduced (45.2 ± 58.9 mL versus 65.3 ± 73.1 mL, P = 0.004), and lymph node yield was higher (21.2 ± 11.4 versus 16.6 ± 7.3, P < 0.001) in the FL group. Postoperative recovery was accelerated, with earlier return of bowel function and shorter hospital stays (9.5 ± 3.1 versus 10.7 ± 3.8 days, P = 0.012). In subgroup analyses, FL significantly reduced AL rates in patients without nCRT (1.9% versus 7.2%, P = 0.045) and demonstrated a strong trend toward reduction in AL for patients receiving nCRT (13.0% versus 35.9%, P = 0.051). FL also increased the proportion of patients achieving benchmark lymph node retrieval, including those post-nCRT.
conclusionsFluorescence-guided laparoscopic surgery reduces anastomotic leakage and improves outcomes in low rectal cancer, especially after chemoradiotherapy, by enhancing surgical precision and recovery.
