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
The present study aimed to investigate the efficacy of indocyanine green (ICG) fluorescence-guided laparoscopic hepatectomy for the treatment of liver metastases. Therefore, data from patients with liver metastases who underwent laparoscopic hepatectomy were retrospectively collected. A total of 69 patients were divided into the ICG group (fluorescence-guided) and conventional group, with 24 well-matched pairs analyzed after propensity score matching. Laparoscopic hepatectomy was successfully performed in all patients.The ICG group had significantly wider surgical margins than the conventional group (1.73 ± 0.57 cm vs. 1.04 ± 0.44 cm; P < 0.001). Pre-matching R0 resection rates were 91.9% (ICG) and 90.6% (conventional), with 100% R0 resection achieved in both groups post-matching. Operative time, intraoperative blood loss and postoperative ALT levels were numerically lower in the ICG group without statistical significance. The rates of overall/severe (Clavien-Dindo ≥IIIa) complications and 6-month recurrence were comparable between the two groups (all P > 0.05). In conclusion, ICG fluorescence-guided laparoscopic hepatectomy is safe and feasible for liver metastases, yielding significantly wider surgical margins. Although perioperative outcomes and 6-month recurrence rates were comparable between groups after matching, the ICG-guided approach achieved significantly wider surgical margins-a finding with potential implications for long-term oncological outcomes that warrant further investigation.
