Intermittent claudication: From its risk factors to its long-term prognosis in men. The Quebec Cardiovascular Study.
Article in The Canadian journal of cardiology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
backgroundThe natural history of intermittent claudication, from its risk factors to its cardiovascular prognosis, has been reported in few prospective studies.
objectiveTo assess incident intermittent claudication, as well as its risk factors and long-term prognosis in men.
methodsA random sample of 4376 men 35 to 64 years of age from Quebec City (Quebec), who were free of cardiovascular disease (CVD), was evaluated in 1974 for CVD risk factors and followed until 1998. To assess the prognosis, the event rates between 1985 and 1998 were computed among men with incident claudication without other CVD, incident survivors of a first myocardial infarction (MI) without other CVD and men free of CVD between 1974 and 1985.
resultsFrom 1974 to 1998, 300 men developed intermittent claudication. Tobacco consumption, high systolic blood pressure and diabetes at least doubled the adjusted RR (aRR) of intermittent claudication. In 1985, there were 80 claudicants, 2868 men free of CVD and 68 survivors of a first MI. During the 13-year follow-up, a new CVD occurred in 48.8% of the claudicants, in 18.9% of men without CVD (aRR 2.08; 95% CI 1.48 to 2.90) and in 45.6% of MI survivors (aRR compared with claudicants 1.12; 95% CI 0.69 to 1.79). There was also no significant difference between claudicants and MI survivors for fatal CVD, nonfatal CVD and total mortality.
conclusionsMen with intermittent claudication are at high risk for CVD that may be equivalent to men with previous MI.
