CCR2-V64I genetic polymorphism: a possible involvement in HER2+ breast cancer.
Review in Clinical and experimental medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Many tumor cells express chemokines and chemokine receptors, and these molecules can affect both tumor progression and anti-tumor immune response. Genetic polymorphisms of some chemokine receptors were found to be closely related to malignant tumors, especially in metastasis process, including breast cancer (BC). Considering this, it was investigated a possible role for CCR2-V64I (C-C chemokine receptor 2) and CCR5-Δ32 (C-C chemokine receptor 5) genetic variants in BC context. Patients were divided into subgroups according to immunohistochemical profile of estrogen (ER) and progesterone (PR) receptors and the human epidermal growth factor receptor 2 (HER2) overexpression. No significant associations were found in relation to susceptibility (CCR2-V64I: OR 1.32; 95 % CI 0.57-3.06; CCR5-∆32: OR 1.04; 95 % CI 0.60-1.81), clinical outcome (tumor size, lymph nodes commitment and/or distant metastasis, TNM staging and nuclear grade) or therapeutic response (recurrence and survival). However, it was found a significant correlation between CCR2-V64I allelic variant and HER2 immunohistochemical positive samples (p = 0.026). All in all, we demonstrate, for the first time, a positive correlation between CCR2 receptor gene polymorphism and a subgroup of BC related to poor prognosis, which deserves further investigation in larger samples for validation.
