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
It is imperative to explore new biocompatible drugs with low toxicity for use in medicinal fields such as fighting tumors. Bovine lactoperoxidase (BLPO) stems from the most important enzymes in the bovine whey that provide a proper pattern for nano-formulation with nanomaterials. LPO is a suitable protein to be coated or adsorbed to alginate modified graphene oxide (GO-SA), which forms the modified GO-SA-LPO hybrid structure. This novel combination provides LPO stability with strong anticancer effects and boosts immunity response. The characterization results obtained from different techniques confirmed a successful LPO adsorption on the GO-SA composite surface. Moreover, nano-formulation of LPO with GO-SA composite exhibited a reduction in its size and overall charge. In addition, the experimental results showed greater LPO activity stability in the modified GO-SA-LPO nanocombination than free LPO after storage for 10 weeks at 4 °C. The in vitro study, a crucial step in the validation of our approach, demonstrated that the modified GO-SA-LPO nanocombination showed a potent anticancer selectivity toward colon cancer cell lines more than GO-SA composite or free form of LPO, which enhanced in a dose-dependent manner with high safety manner against normal cells. The apoptotic effect of this novel nanocombination was confirmed by the greatest variations in the expression of both well-known apoptosis genes (p53 and Bcl-2), severe changes in the cellular morphology, DNA fragmentation, and nuclear staining with fluorescence yellow and orange of the target cancer cells. Also, this superior efficacy of the modified GO-SA-LPO nanocombination was induced by suppressing some pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin (IL-6), and necrosis factor-kappa B (NF-ĸB). Our observations presented that the modified nanocombination of LPO may offer a novel remedy for treating colon tumors via induced apoptosis pathway, inflammation reduction, and immune response improvement.
