Evaluating Variations in Indocyanine Green Administration and Its Impact on Nodal Yield in Oesophagogastric Cancer Surgery.

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
backgroundIndocyanine green (ICG), a near-infrared fluorescent dye, has the potential to improve oncological outcomes by increasing lymph node yield in oesophagogastric (OG) cancer. There is no consensus regarding the dose, timing, and method of injection. This study was designed to evaluate the variation in ICG administration and its potential impact on nodal yield in OG cancer surgery for the purpose of translation in Western patients.
methodsA systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The primary outcome of this review was nodal yield, and the secondary outcome was the diagnostic accuracy of ICG in detecting metastatic lymph nodes. A meta-analysis of diagnostic accuracy data was performed by using a random-effects model.
resultsA total of 38 studies (12,138 patients) were included in the analysis. Nodal yield was significantly increased in the ICG groups by 7.6 nodes (95% confidence interval [CI] 5.9-9.4; P = 0.0001) compared with control. Trends towards greater nodal yield were observed when ICG was administered at doses less than 2.75 mg, on the day before surgery, and via subserosal injection, although these did not reach statistical significance. Of the 17 studies with diagnostic accuracy data, the pooled sensitivity and specificity of ICG were 0.81 (95% CI 0.67-0.90) and 0.41 (95% CI 0.29-0.53), I
conclusionsIndocyanine green-assisted lymphadenectomy significantly increased lymph node yield, which may translate into improved survival in patients with OG cancer. The ICG dose, timing, and method of injection warrant standardisation to maximise its potential benefits in Western patients.
