Postmenopausal Breast Cancer Risk in Relation to Antibodies Specific to Benzo[a]Pyrene, Estradiol and Progesterone.

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
backgroundAntibodies might protect against low doses of environmental carcinogens by decreasing systemic uptake, activation of metabolic pathways, and redistribution of carcinogens within the organism. The features of antibody formation in relation to environmental carcinogens and sex steroids under natural conditions should be determined to identify breast cancer risk, then to develop cancer immune prevention strategies.
objectivesThe purpose of this study was to investigate antibodies specifications to benzo(a)pyrene, estradiol and progesterone in postmenopausal women with invasive breast cancer. PATIENTS AND
methodsA semi-quantitative non-competitive immunoassay of IgG antibodies to benzo(a)pyrene (IgG-Bp), estradiol (IgG-Es), and progesterone (IgG-Pg) has conducted. The assay has performed on 322 serum samples from patients with breast cancer and 179 serum samples from healthy postmenopausal women by using low-molecular-weight Bp, Es, and Pg conjugated with bovine serum albumin. ROC analysis has also conducted to determine the odds ratio (OR).
resultsCombination of the high levels of IgG-Bp and IgG-Es without IpG-Pg was more frequent in breast cancer patients than that in healthy women, and the OR has increased to 3.8. Combination of the high levels of IgG-Pg with high levels of both IgG-Bp and IgG-Es were significantly more frequent in breast cancer patients (36.9%) than that in healthy women (5.6%), and the OR increased to 11.7. These differences have peculiarly expressed in breast cancer patients with hormone status ER+/PR- (OR = 26.7). The minimum OR (0.4) has obtained at low levels of the three antibodies.
conclusionsImmunoassay of antibodies against environmental carcinogens and sex steroid hormones could use to detect breast cancer risk. Induction of antibodies against Bp for cancer immunoprevention could lead to antibody formation against steroid hormones, thereby increasing breast cancer risk.
