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

purposeIn vitro anticancer effect and in vivo biodistribution and biocompatibility of metformin encapsulated O-Carboxymethyl chitosan nanoparticles were evaluated for its application as pancreatic cancer therapy.

methodsIn vitro studies such as cell migration assay, clonogenic assay, cell cycle analysis and qRT-PCR analysis were done in pancreatic cancer cells (MiaPaCa-2) treated with O-CMC-metformin NPs for evaluating its anticancer potential. In vivo biodistribution studies were carried out by NIR imaging of O-CMC-metformin NPs after tagging it with ICG. In vivo biocompatibility of the NPs was assessed by histopathology analysis of organs from mice administered with the NPs.

resultsIn vitro cell migration assay showed marginal effect of NPs on migration property of pancreatic cancer cells (MiaPaCa-2). In vitro clonogenic assay established that the O-CMC-metformin NPs reduced colony formation ability of the cancer cells. While cell cycle analysis showed that the O-CMC-metformin NPs had only minor effect on progression of cell cycle in the cancer cells. qRT-PCR analysis exhibited reduced mRNA expression of p21, vanin 1 and MMP9 in pancreatic cancer cells treated with the nanoparticles. In vivo NIR imaging study showed normal biodistribution pattern of the intravenously injected O-CMC-metformin NPs suggesting normal clearance rate of nanoparticles and no adverse toxicity to the organs.

conclusionsThe biocompatible O-CMC-metformin NPs with anticancer potential and capability for normal biodistribution can be beneficial for the treatment of pancreatic cancer.
