Long-term follow up of patients who were positive for peritoneal lavage cytology: final report from the CCOG0301 study.
Trial report in Gastric cancer : official journal of the International Gastric Cancer Association and the Japanese Gastric Cancer Association, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 57 papers, 4 of them syntheses that pooled 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.
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
backgroundIn gastric cancer patients who have positive results for peritoneal lavage cytology the disease is defined as CY1, and classified as stage IV, and this population has generally suffered a dismal outcome. For this population, we had conducted a phase II trial, with the 2-year survival rate as the primary endpoint, to test the strategy of D2 dissection followed by chemotherapy with single-agent S-1 (1 M tegafur-0.4 M gimestat-1 M otastat potassium). Forty-eight patients were enrolled, of whom 47 were found to have been eligible for analysis. The 2-year survival rate of 46 % exceeded our expectations.
methodsFurther follow up was conducted to confirm whether radical surgery could be recommended for the CY1 population.
resultsThe 5-year overall and relapse-free survival rates were 26 and 21 %, respectively.
conclusionsGastrectomy with curative intent could be considered for patients with CY1 disease provided they are scheduled to receive effective postoperative chemotherapy.
