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: The preoperative application of computed tomography (CT), particularly suture hook anchor (SHA) and indocyanine green (IG) injection, for guiding the localization of pulmonary nodules (PNs) is increasingly used. Nevertheless, these two approaches have not been compared in terms of safety and performance. Here, the effectiveness and safety of CT-guided SHA and IG localization for multiple PNs during video-assisted thoracoscopic surgery (VATS) were evaluated. Methods: Consecutive cases with multiple PNs that received SHA or IG under CT guidance before VATS between January 2022 and December 2024 were retrospectively analyzed. Localization success, procedure duration, complication rates, and VATS-related outcomes analyzed. Results: Seventy-four cases were enrolled, of which 36 (79 nodules) underwent SHA localization, and 38 (92 nodules) underwent IG localization. All patients successfully underwent one-stage localization and subsequent VATS resection. The technical success rates for both procedures were 100%. The IG-mediated procedure was markedly shorter than SHA (10.6 ± 4.4 min vs. 23.4 ± 11.9 min, P = 0.001). The incidence of pneumothorax (27.8% vs. 36.8%, P = 0.405) and pulmonary hemorrhage (38.9% vs. 21.1%, P = 0.093) was comparable between the two procedures. VATS limited resections were technically successful in all patients (100% in both groups), with all nodules resected in a single operative session. The median operative duration was comparable between the SHA and IG groups (85 minutes vs. 80 minutes, P = 0.269). Conclusions: Both SHA and IG-mediated localization under CT guidance safe and effective for the preoperative evaluation of multiple PNs. While outcomes were similar across both methods, IG localization demonstrated the advantage of significantly reduced localization time, suggesting it may be a more time-efficient option in clinical practice.
