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

Peripheral artery disease (PAD) is associated with exercise impairment and greater thrombotic risk. We investigated whether clot formation and platelet aggregation assessed by thromboelastography and light-transmission aggregometry correlate with the severity of symptomatic PAD assessed by ambulatory function measures. We studied 40 symptomatic patients with PAD in whom severity of disease was assessed using ankle-brachial index, peak walking time (PWT), claudication onset time, peak oxygen uptake, daily ambulatory activity, and walking impairment questionnaire (WIQ) scores. Clot strength correlated negatively with peak oxygen uptake, PWT, WIQ distance, and stair-climbing scores. Time to clot formation did not correlate with exercise parameters. Platelet aggregation was negatively correlated with WIQ distance score and was positively correlated with PWT and peak oxygen uptake. In conclusion, clot strength and platelet aggregation correlated with objective and self-perceived ambulatory measures. Patients with PAD having more severe walking impairment may be likely to form stronger clots.
