Comparison of CDH1 Gene Hypermethylation Status in Blood and Serum among Gastric Cancer Patients.
Article in Pathology oncology research : POR, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hypermethylation is epigenetic alteration, well known for gene silencing. CHD1 gene is known as invasion and tumor suppressor gene, decreased expression due to hypermethylation could promote tumor cell invasion and metastasis. Present study designed to investigate the CDH1 gene promoter hypermethylation status by methylation specific polymerase chain reaction in 100 newly diagnosed gastric cancer patients. 53% of hypermethylation was observed in DNA extracted from blood in Gastric cancer patients while 66% was observed in serum based DNA. Significant differences in CDH1gene promoter hypermethylation was observed in serum based DNA extracted from Gastric cancer patients. Patients in early stage (I & II) vs advanced stage (III & IV), distant organ metastases vs no metastases had 60% vs 7% and 42% 24% of CDH1 promoter hypermethylation in serum DNA (p = 0.006, 0.001) respectively. Patients who were with lymph node invasion, loss of appetite, loss of weight had 55%, 47%, 61% CDH1 gene promoter hypermethylation compare to who were not with lymph node invasion, loss of appetite, loss of weight had 11%, 19%, 5% of hypermethylation and these differences was found to be significant. Strong association was observed with overall median survival of patients (p < 0.0001). Patients who had CDH1 gene promoter hypermethylation in serum based DNA showed poor overall median survival (14.3 months) and unmethylated patients had better overall median survival (33.2 months). CDH1 hypermethylation status was found to be associated with advancement of disease, distant organ metastases and lymph node invasion in Gastric cancer patients.
