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

purposeTo develop a drug-delivery system for the prolonged retention of intraperitoneally (i.p.) administered cisplatin (CDDP) to deliver intraperitoneal chemotherapy against peritoneal carcinomatosis effectively.

methodsCDDP was encapsulated inside an in situ cross-linkable hyaluronic acid (HA)-based hydrogel. The gelation and degradation kinetics of the hydrogel and the release kinetics of CDDP were investigated in vitro, and the antitumor effect was investigated in a mouse model of peritoneal dissemination of human gastric cancer.

resultsThe gelation time varied according to the concentration of two polymers: HA-adipic dihydrazide and HA-aldehyde. CDDP was released from the hydrogel for more than 4 days. A cell proliferation assay showed that the polymers themselves were not cytotoxic toward MKN45P, a human gastric cancer cell line. By mixing the two polymers in the peritoneum, in situ gelation was achieved. The weight of peritoneal nodules decreased in the hydrogel-conjugated CDDP group, whereas no significant antitumor effect was observed in the free CDDP group.

conclusionsIn situ cross-linkable HA hydrogels represent a promising biomaterial to prolong the retention and sustain the release of intraperitoneally administered CDDP in the peritoneal cavity and to enhance its antitumor effects against peritoneal dissemination.
