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: Lymphaticovenous anastomosis (LVA) is an effective surgical treatment for extremity lymphedema. Indocyanine green (ICG) fluorescent lymphography, the traditional standard for imaging lymphatic vessels, has limitations, including difficulty depicting deeper or congested lymphatics and contraindication in iodine hypersensitivity. This study evaluated contrast-enhanced ultrasound (CEUS) with microbubbles for identifying lymphatic vessels for LVA and compared it with ICG lymphography. Methods: In this single-center retrospective review, intraoperative CEUS with intradermal injection of microbubble suspension (Lumason, Bracco Diagnostics, Inc.) was used in patients before LVA surgery between October 2019 and February 2023. Pre- or intraoperative ICG lymphography was also used to identify target lymphatic vessels. All patients diagnosed with primary or secondary extremity lymphedema who underwent LVA were included. Technical success rate was defined as lymphatic vessels identified by CEUS that led to successful LVAs. Descriptive statistics were used. Results: Thirty-two patients underwent LVA surgery, with a mean age of 58.5 ± 13.9 years. CEUS identified lymphatic vessels in all 32 patients, including 7 in whom ICG failed. Two patients with ICG allergy underwent CEUS only. CEUS identified more candidate lymphatics per patient (5.3 ± 4.2) compared with ICG (2.5 ± 2.7). Of the 182 anastomoses, 96 (52.8%) were identified by both CEUS and ICG, 75 (41.2%) by CEUS only, and 11 (6%) by ICG only. Conclusions: CEUS is a promising tool for identifying lymphatic vessels in patients with lymphedema undergoing LVA, particularly when ICG lymphography is inadequate or contraindicated.
