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

unlabelledBisphosphonates have been associated with an increased risk of atrial fibrillation and may thus be associated with an increased risk of ischemic stroke. This would have substantial clinical and public health implications. We found no evidence of an association between bisphosphonate use and risk of ischemic stroke.

introductionBisphosphonates have been associated with an increased risk of atrial fibrillation in some studies and may be associated with an increased risk of ischemic stroke. However, data regarding these possibilities are limited.

methodsWe conducted a population-based case-control study of 6,257 female cases of ischemic stroke and 31,285 age- and gender-matched population controls. Data on bisphosphonate use, other medication use, comorbidity, and ischemic stroke were obtained from medical databases. Current bisphosphonate use was defined as at least one redeemed prescription within 90 days before diagnosis/index date. We estimated the odds ratio (OR) of ischemic stroke among users and nonusers of bisphosphonates using conditional logistic regression, controlling for potential confounding factors.

resultsOne hundred eighty-two (2.9%) cases and 901 (2.9%) controls were current users of bisphosphonates. Etidronate and alendronate were prescribed with similar frequency among cases and controls. The adjusted OR of ischemic stroke for bisphosphonate users compared with nonusers was 0.97 (95% confidence interval [CI], 0.82-1.15). New and continuing bisphosphonate users had adjusted ORs for ischemic stroke of 1.16 (95% CI, 0.69-1.96) and 0.97 (95% CI, 0.81-1.16), respectively. Excluding patients with known atrial fibrillation/flutter yielded an OR of 1.00 (95% CI, 0.85-1.19). The OR for ischemic stroke was 0.59 (95% CI, 0.32-1.09) among patients with a history of previous hospitalization for cardiovascular disease and 1.07 (95% CI, 0.88-1.18) among those without (P < 0.001). The OR for former users was 1.23 (95% CI, 1.01-1.49).

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