Clinical Significance of Female-hormones and Cytokines in Breast Cancer Patients Complicated with Aromatase Inhibitor-related Osteoarthropathy - Efficacy of Vitamin E.

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
introductionAromatase inhibitor use for postmenopausal hormone-sensitive breast cancer patients often results in drug-induced osteoarthropathy, while its accurate mechanism has not been clarified. We investigated the implication of female hormones and several cytokines in osteoarthropathy complicated with aromatase inhibitor treatment, and the efficacy of vitamin E on the severity of osteoarthropathy, in breast cancer patients.
methodsSixty two breast cancer patients treated with aromatase inhibitor for average of 1.77 years were included. These patients were orally administered vitamin E (150mg/day) for 29.8 days to alleviate aromatase inhibitor-related osteoarthropathy. Severity of osteoarthropathy was scored, and the patients were grouped based on the severity or vitamin E efficacy. Serum estradiol, progesterone, vitamin E, interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), IL-2, IL-4, IL-6, IL-10, and IL-17A concentrations were measured by ELISA or beads array procedures followed by flow cytometry.
resultsThere was no significant difference in serum concentrations of the biomarkers between the severe and the mild osteoarthropathy groups before vitamin E administration. The osteoarthropathy scores significantly decreased after vitamin E administration (p=0.0243), while serum-estradiol concentrations did not change. The serum-estradiol concentrations before vitamin E administration in the group sensitive to the vitamin E efficacy were significantly lower, as compared with those in the insensitive group (p=0.0005). The rate of the highly sensitive patients to the vitamin E efficacy in those exhibiting low serum-estradiol concentrations was significantly higher than that in the high serum-estradiol group (p=0.0004). In the sensitive group, serum-estradiol concentrations after taking vitamin E were significantly higher than those before taking vitamin E (p=0.0124).
conclusionsVitamin E administration seemed to be a potential way for relieving osteoarthropathy complicated with aromatase inhibitor use. Using serum-estradiol concentration, it would be possible to select out the breast cancer patients who will respond well to the vitamin E therapy for osteoarthropathy complicated with aromatase inhibitor.
