1 · What the graph read from it

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.

2 · The registry

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

purposeIndocyanine green (ICG) is a promising agent for intraoperative visualization of tumor tissues and sentinel lymph nodes in early-stage gynecological cancer. However, it has some limitations, including a short half-life and poor solubility in aqueous solutions. This study aimed to enhance the efficacy of near-infrared (NIR) fluorescence imaging by overcoming the shortcomings of ICG using a nano-drug delivery system and improve target specificity in cervical cancer. MATERIALS AND

methodsICG and poly(lactic-co-glycolic acid) (PLGA) conjugated with polyethylenimine (PEI) were assembled to enhance stability. Hyaluronic acid (HA) was coated on PEI-PLGA-ICG nanoparticles to target CD44-positive cancer cells. The manufactured HA-ICG-PLGA nanoparticles (HINPs) were evaluated in vitro and in vivo on cervical cancer cells (SiHa; CD44+) and human dermal cells (ccd986sk; CD44-), respectively, using NIR imaging to compare intracellular uptake and to quantify the fluorescence intensities of cells and tumors.

resultsHINPs were confirmed to have a mean size of 200 nm and a zeta-potential of 33 mV using dynamic light scattering. The stability of the HINPs was confirmed at pH 5.0-8.0. Cytotoxicity assays, intracellular uptake assays, and cervical cancer xenograft models revealed that, compared to free ICG, the HINPs had significantly higher internalization by cervical cancer cells than normal cells (

conclusionThis study demonstrated the successful application of HINPs as nanocarriers for delivering ICG to CD44-positive cervical cancer, with improved efficacy in NIR fluorescence imaging.
