Epstein-Barr virus and breast cancer: lack of evidence for an association in Iranian women.
Trial report in Pathology oncology research : POR, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 2 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
Controversies regarding the role of Epstein-Barr virus (EBV) in breast cancer and lack of published literature in this regard in Iran, prompted us to assess EBV presence in 100 breast carcinoma and 42 control biopsies obtained from Iranian women. Breast carcinoma cases were comprised of 81 invasive ductal carcinoma NOS, 9 invasive lobular carcinoma, 1 apocrine carcinoma, 2 cribriform carcinoma, 2 papillary carcinoma and 5 mucinous carcinoma. Control biopsies consisted of 13 fibroadenoma, 9 benign epithelial proliferation (adenosis and sclerosing adenosis), 9 usual ductal hyperplasia, 4 atypical ductal hyperplasia, 4 non-proliferative fibrocystic changes and 3 normal breast tissue. To identify EBV-infected cells we applied immunohistochemical analysis, using monoclonal antibody against Epstein-Barr virus-encoded nuclear antigen 2 (EBNA-2) and latent membrane protein 1 (LMP-1). Further, polymerase chain reaction (PCR) was used to amplify EBV DNA, with primers that cover the EBV encoded RNA (EBER) and BamHIW regions. EBNA-2 and LMP-1 immunohistochemistry were negative in all breast cancer and control specimens. Using PCR, none of the 100 breast cancer samples or the 42 control specimens showed detectable EBV DNA. These results indicate that EBV may not play a significant role in the etiology of breast cancer in Iranian women.
