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

purposeWe conducted this retrospective study to evaluate the effectiveness of giving oral anti-cancer drugs for 2 years as postoperative adjuvant chemotherapy to gastric cancer patients.

methodsThe subjects were 76 patients with stage II and III gastric cancer, who underwent curative surgery between 1989 and 2008. We divided the 20 years chronologically into the UFT term (1989-2003) and the S-1 term (2004-2008). The patients from each term were then divided into three groups according to the length of drug administration; namely, the surgery alone group, the 1-year group, and the 2-year group.

resultsThe survival time of the 2-year group was better than that of the surgery alone group, not only in the UFT term, but also in the S-1 term (P = 0.0224). Longer relapse-free survival was evident in the S-1 term, especially for the 2-year group (P = 0.0110). A multivariate analysis showed both the stage of the cancer and 2 years of postoperative adjuvant chemotherapy to be independent factors predictive of prolonged survival (P = 0.0040 and P = 0.0022, respectively).

conclusionsThe 2-year administration of oral anti-cancer drugs as postoperative adjuvant chemotherapy might improve the outcome of stage II, III gastric cancer patients. Randomized control trials are warranted to prove the effectiveness of this 2-year regimen.
