Application of an indocyanine green-mediated fluorescence imaging navigation system in detecting mice tumors.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSurgical operation plays an important role in the treatment of cancer. The success of the operation lies in the complete removal of the primary and disseminated tumor tissue while preserving the normal tissue. The development of optical molecular image navigation technology has provided a new option for intraoperative tumor visualization. In this study, a fluorescence imaging navigation system was used to detect the diameter of mice tumors and provide experimental evidence for the further development of digital diagnosis and treatment equipment.
methodsThe minimum detection concentration in vitro of the fluorescence imaging navigation system for indocyanine green (ICG) was first detected, then 120 female Institute of Cancer Research (ICR) mice and 120 female BALB/c nude mice were randomly divided into three groups by weight, high-dose (H, 4 mg/kg), middle-dose (M, 2 mg/kg), and low-dose (L, 1 mg/kg) groups of ICG solution. After inoculating solid tumors, high, medium, and low doses of ICG were injected via the tail vein, and the tumor diameter was measured by a fluorescence imaging navigation system and vernier caliper within 24 hours of injection.
resultsThe minimum detectable diameter of the system could reach 0.2 mm compared with the vernier caliper, and the actual measurement error was within 0.2 mm.
conclusionsA fluorescence imaging navigation system has high accuracy and sensitivity in the application of tumor detection, which may assist the clinical diagnosis and treatment of tumors.
