FEN1 gene variants confer reduced risk of breast cancer in chinese women: A case-control study.
Article in Oncotarget, 2016. 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
This study aimed to assess the associations of two common Flap endonuclease 1 (FEN1) polymorphisms (rs4246215 and rs174538) with breast cancer risk in northwest Chinese women. We conducted a case-control study with 560 breast cancer patients and 583 age-matched healthy controls from Northwest China. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to estimate the associations. We found a significantly reduced risk of breast cancer associated with T allele of rs4246215 (allele model: OR 0.81, 95% CI 0.68-0.96; homozygote model: OR = 0.59, 95% CI = 0.40-0.87; recessive model: OR = 0.61, 95% CI = 0.42-0.89), especially in postmenopausal women (OR = 0.58, 95% CI = 0.35-0.97). Furthermore, the polymorphism showed a decreased association with larger tumor size (heterozygote model: OR = 0.63, 95% CI = 0.44-0.92; dominant model: OR = 0.63, 95% CI = 0.44-0.90). For rs174538, we did not find any difference in all genetic models. However, rs174538 was associated with lymph node metastasis (heterozygote model: OR = 0.57, 95% CI = 0.39-0.81; dominant model: OR = 0.61, 95% CI = 0.43-0.86) and estrogen receptor status (heterozygote model: OR = 1.50, 95% CI = 1.05-2.15; dominant model: OR = 1.42, 95% CI = 1.01-1.98). Haplotype analysis showed that Trs4246215Grs174538 haplotype was a protective factor of breast cancer (OR = 0.34, 95% CI = 0.14-0.81). Our results suggest that FEN1 polymorphisms may reduce the risk of breast cancer in Chinese women.
