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

backgroundTo establish a primary human gastric cancer cell line.

methodsFresh gastric cancer tissue samples were separated into a cell suspension, and DMEM/F12 medium containing 10% foetal bovine serum was used for primary culture and subculture. The morphology of the cells was observed under a light microscope, and the cell growth curve was plotted. A soft agar colony formation assay was used to detect the colony formation ability of the cell line. Immunohistochemical methods were used to detect cytokeratin, vimentin and Ki-67, the chromosome G banding method was used to analyse the karyotype of the cells, and the tumourigenic ability of the cells was detected by subcutaneous inoculation of BALB/C nude mice.

resultsWe established a gastric cancer cell line from a 68-year-old male patient. This gastric cancer cell line was named XGC-1 and had a doubling time of approximately 48 h. The cell line displayed strong colony formation ability and tumourigenicity in BALB/C nude mice and had complicated chromosomal abnormalities. When nutrients were insufficient, the cells shed and floated in the medium, but adherent growth was observed in nutrient-rich conditions.

conclusionsThe XGC-1 cell line will be useful for future studies of gastric cancer development, progression, metastasis and therapy.
