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

Context: Pioglitazone reduces cardiovascular risk in nondiabetic patients after an ischemic stroke or transient ischemic attack (TIA) but is associated with increased risk for bone fracture. Objective: To characterize fractures associated with pioglitazone by location, mechanism, severity, timing, and sex. Design, Setting, and Patients: Patients were 3876 nondiabetic participants in the Insulin Resistance Intervention after Stroke trial randomized to pioglitazone or placebo and followed for a median of 4.8 years. Fractures were identified through quarterly interviews. Results: At 5 years, the increment in fracture risk between pioglitazone and placebo groups was 4.9% [13.6% vs 8.8%; hazard ratio (HR), 1.53; 95% confidence interval (CI), 1.24 to 1.89). In each group, ∼80% of fractures were low energy (i.e., resulted from fall) and 45% were serious (i.e., required surgery or hospitalization). For serious fractures most likely to be related to pioglitazone (low energy, nonpathological), the risk increment was 1.6% (4.7% vs 3.1%; HR, 1.47; 95% CI, 1.03 to 2.09). Increased risk for any fracture was observed in men (9.4% vs 5.2%; HR, 1.83; 95% CI, 1.36 to 2.48) and women (14.9% vs 11.6%; HR, 1.32; 95% CI, 0.98 to 1.78; interaction P = 0.13). Conclusions: Fractures affected 8.8% of placebo-treated patients within 5 years after an ischemic stroke or TIA. Pioglitazone increased the absolute fracture risk by 1.6% to 4.9% and the relative risk by 47% to 60%, depending on fracture classification. Our analysis suggests that treatments to improve bone health and prevent falls may help optimize the risk/benefit ratio for pioglitazone.
