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

Recent data have implicated telomere-length shortening as potential risk predictor for vascular diseases, including stroke. However, to date, prospective epidemiological data are scarce in relation to ischemic stroke risk. Using leukocyte DNA samples collected at baseline in a prospective cohort of 14,916 initially healthy American men, we examined the relationship of leukocyte telomere repeat copy number to single gene copy number (TSR), using a quantitative polymerase chain reaction protocol, amongst 259 white males who subsequently developed an ischemic stroke and amongst an equal number of age- and smoking-matched white males who remained free of reported vascular disease during follow up (controls). The observed TSRs were inversely correlated with age in the controls (p < 0.0001). However, the observed TSRs were similar between cases and controls (p = 0.92). In a multivariable adjusted analysis, no evidence was found for an association of the TSRs with ischemic stroke risk (odds ratio [OR] = 1.100, 95% confidence interval [CI], 0.506-2.392, p = 0.811). The present investigation has shown no evidence for an association of relative leukocyte telomere length with risk of incident ischemic stroke. More importantly, our present findings require replication/confirmation in future large, prospective studies.
