Clinicopathological features and trend changes of gastric carcinoma in Southern China.
Article in World journal of gastroenterology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo investigate the clinicopathological features of gastric carcinoma in southern China and disease trends changes over the last 18 years.
methodsWe designed a retrospective study in the Department of Gastrointestinal Surgery, the first affiliated hospital, Sun Yat-sen University. A total of 2100 adult patients with definitely diagnosed, histologically proven gastric carcinomas treated with radical gastrectomy from 1994 to 2013 were examined retrospectively. In all cases patient age, gender, tumor location, Borrmann type, histopathological type and grade, and pTNM stage were identified and recorded. The information was obtained from hospital records. The data were analyzed with Stata12.0 software.
resultsIn this study, the mean age of patients was 57 years with a range from 19-89 years. A higher incidence was found in patients over 60 years of age. In the study population, 67.38% of patients were male and 32.62% were female. Women had a higher disease incidence than men in patients less than 40 years of age (P < 0.001). No obvious change of patient age and gender was observed in the last 18 years. The rates of disease by location were the following: antrum (44.57%), followed by fundus/ body (24.95%) and cardia/gastroesophageal junction (23.00%). The mean tumor diameter was 5.57 cm, and advanced gross type Borrmann III was most common. Most patients were at advanced stages when first diagnosed, and patients with early stage disease were relatively rare. More early stage patients were detected in recent years, especially after 2000 (P < 0.001). Gastric carcinoma has different features in young and old patients. The young patients had the following features: more frequently female, tumors in the antrum, larger tumor size, poorly differentiated carcinoma, high rate of metastasis to other sites and advanced stages (P < 0.05).
conclusionIn southern China, gastric carcinoma was more frequent in old men and young women. Young and old patients should be treated differently for having different features.
