1 · What the graph read from 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.

2 · The registry

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

purposeBisphosphonates are commonly used for the treatment of osteoporosis and for prevention and treatment of skeletal lesions due to malignancy. However, the association between the use of bisphosphonates and the risk of developing breast cancer has not been reported. PATIENTS AND

methodsThe Breast Cancer in Northern Israel Study is a population-based case-control study in northern Israel of patients with breast cancer and age-, clinic-, and ethnic-group matched controls. Use of bisphosphonates was assessed in 4,039 postmenopausal patients and controls, members of Clalit Health Services, using pharmacy records.

resultsThe use of bisphosphonates for longer than 1 year before diagnosis, but not for shorter than 1 year, was associated with a significantly reduced relative risk of breast cancer (odds ratio [OR], 0.61; 95% CI, 0.50 to 0.76). This association remained significant after adjustment for age, fruit, and vegetable consumption, sports activity, family history of breast cancer, ethnic group, body mass index, use of calcium supplements, hormone replacement therapy use, number of pregnancies, months of breast feeding, and age at first pregnancy (OR, 0.72; 95% CI, 0.57 to 0.90). Breast cancer risk did not change further if bisphosphonates were used for more years. Breast tumors identified in bisphosphonates users were more often estrogen receptor positive and less often poorly differentiated.

conclusionThe use of bisphosphonates for longer than 1 year was associated with a 28% relative reduction in the risk of postmenopausal breast cancer. Tumors developing under bisphosphonates treatment tended to have a favorable prognostic factors profile.
