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

unlabelledOral bisphosphonates are widely used for fracture prevention, but there is a concern regarding potential adverse cardiovascular effects of bisphosphonates. In this large, population-based case-control study, we found no evidence of an association between bisphosphonate use and risk of venous thromboembolism (VTE).

introductionWe examined the relation between the use of oral bisphosphonates for osteoporosis and the risk of VTE.

methodsWe conducted a population-based case-control study in Northern Denmark (population, 1.7 million). Using the Danish National Registry of Patients, we identified all women with a first-time hospital diagnosis of VTE between 1999 and 2006. For each case, we selected up to ten female population controls, matched on date of the index VTE event and age. Data on use of oral bisphosphonates, other medications, and comorbidity were obtained from medical databases. We used logistic regression to estimate odds ratios (OR) for VTE associated with bisphosphonate users while adjusting for potential confounding factors.

resultsFour thousand one hundred ninety-three cases and 41,197 controls were included in the study. One hundred forty-nine cases (3.6%) and 1,078 controls (2.6%) were current bisphosphonate users. The adjusted OR for VTE among the current bisphosphonate users compared with nonusers was 1.03 (95% confidence interval (CI): 0.84-1.26), and when restricted to cases of unprovoked thromboembolism, the adjusted OR was 1.08 (95% CI: 0.82-1.42). There was no association either for pulmonary embolism or for deep venous thrombosis.

conclusionWe found no evidence of an association of oral bisphosphonate use with the risk of VTE.
