Smoking cessation and mortality among middle-aged and elderly Chinese in Singapore: the Singapore Chinese Health Study.

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
objectiveThis study determines if recent smoking cessation, compared with long-term cessation, can reduce mortality risk associated with smoking.
methodsData from the Singapore Chinese Health Study, a cohort study of middle-aged and elderly Chinese in Singapore, were analysed (n=48 251). Smoking status was evaluated at recruitment between 1993 and 1998 and reassessed between 1999 and 2004. Participants were classified as never-smokers, long-term quitters (quit before recruitment, mean 17.0 years), new quitters (quit between recruitment and second interview, mean 4.3 years) and current smokers. Mortality was ascertained by linkage with the nationwide death registry.
resultsAfter a mean follow-up of 8.1 years, 6003 deaths had occurred by 31 December 2009. Compared with current smokers, the adjusted HR (95% CI) for total mortality was 0.84 (0.76 to 0.94) for new quitters, 0.61 (0.56 to 0.67) for long-term quitters and 0.49 (0.46 to 0.53) for never-smokers. New quitters had 24% reduction in lung cancer mortality (HR: 0.76, 95% CI 0.57 to 1.00) and long-term quitters had 56% reduction (HR: 0.44, 95% CI 0.35 to 0.57). Risk for coronary heart disease mortality was reduced in new quitters (HR: 0.84, 95% CI 0.66 to 1.08) and long-term quitters (HR: 0.63, 95% CI 0.52 to 0.77), although the result for new quitters was of borderline significance due to relatively small number of cardiovascular deaths. Risk for chronic pulmonary disease mortality was reduced in long-term quitters but increased in new quitters.
conclusionSignificant reduction in risk of total mortality, specifically for lung cancer mortality, can be achieved within 5 years of smoking cessation.
