Impact of ABO blood group on the prognosis of patients undergoing surgery for esophageal cancer.
Article in BMC surgery, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03644901 (Investigating the Role of ABO Blood Group in the Response to the Nonsurgical Periodontal Treatment.), which is not on this map. Cited by 8 papers.
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.

Abstract
backgroundABO blood type is an established prognostic factor in several malignancies, but its role in esophageal cancer (EC) is largely unknown. The aim of this study is to determine whether ABO blood group is associated with survival after esophagectomy for EC.
methodsA total of 406 patients who underwent surgery for EC were enrolled. The associations of ABO blood group with clinical and pathological variables were assessed using chi-square test. Associations of ABO blood group with the survival were estimated using univariable and multivariable Cox proportional hazards regression models.
resultsThe ABO blood group proportionally associated with the grade of EC tumor (P = 0.049). The ABO blood group status did not correlate with disease-free survival (DFS) in univariable analysis or multivariable analysis (P > 0.05). And there was no significant relationship between the ABO blood group and overall survival (OS) in univariable analysis or multivariable analysis (P > 0.05).
conclusionsOur results suggested that no association between ABO blood group and the survival was observed in patients undergoing surgery for EC.
