New diagnostic strategy using narrow-band imaging (NBI) during laparoscopic surgery for patients with colorectal cancer.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAccurate tumor stage diagnosis during laparoscopic surgery remains difficult. We clarify the impact of new diagnostic strategy using narrow-band imaging (NBI) during laparoscopic surgery for colorectal cancer compared with other strategies.
methodsWe defined angiogenesis (Ag) and fibrosis (Fib) grades using NBI laparoscopy (lap-NBI), and assessed the clinicopathological features associated with these grades for 67 patients with colorectal cancer who underwent surgery. We assessed vessel density and gray scale with computer software.
resultsNBI-Ag-grade and NBI-Fib-grade of the serosal surface of cancer lesions and peritoneal nodules correlated with vessel density and gray scale of those assessed by Image J computer software. NBI-Fib-grades of liver nodules also correlated with gray scale. NBI-Ag- grade and Fib-grade of the serosal surface of cancer lesions correlated with pathological depth of invasion. These NBI grades of pathological metastatic peritoneal nodules were higher than those of pathologically benign peritoneal nodules. NBI- Fib grades of pathological metastatic liver nodules were higher than those of pathologically benign liver nodules. In multivariate analysis, lap-NBI was associated with different diagnosis for T3, T4 and non-T3, and non-T4. Moreover, lap-NBI was associated with different diagnosis for T4 and non-T4. Predictive value for T4 by lap-NBI showed high sensitivity (85%) specificity (87%), positive predictive value (74%), negative predictive value (93%), and overall accuracy (87%). Sensitivity and overall accuracy of lap-NBI was superior to that of other diagnostic modalities.
conclusionWe clarified the usefulness of the new diagnostic strategy using lap-NBI during laparoscopic surgery for colorectal cancer in comparison with other strategies.
