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.

Abstract

rationaleThere are over 300 million Chinese smokers, but use of nicotine replacement therapy (NRT) is rare. On the other hand, data on the factors associated with quitting and adherence to NRT use are scarce in the East.

objectivesTo describe adherence and other predictors of quitting smoking at the 12-month follow-up amongst Chinese smokers in Hong Kong.

methodsChinese smokers (1186) who attended the Smoking Cessation Health Centre from August 2000 through January 2002 were studied. Trained counsellors provided individual counselling and carried out follow-up interviews. We used structured questionnaires at baseline and at 1, 3 and 12 months and an intention-to-treat approach for analysis.

resultsAmong those who received NRT (1051/1186), the prevalence of adherence (self-reported NRT use for at least 4 weeks) was 16% (95% confidence interval 14-18%). The 7-day point prevalence quit rate at 12 months (not smoking any cigarette during the past 7 days at the 12 month follow-up) was 27% (95% CI, CI 24-29%). Stepwise logistic regression model showed that adherence to NRT use, a higher income, good perceived health and having more confidence in quitting were significant predictors of quitting. The quit rate in the adherent group (40%) was greater than that of the non-adherent group (25%) (P<0.001). Older age, male, higher education, experience of NRT use, perceiving quitting as more difficult and willingness to pay were significant predictors of adherence.

conclusionsClinically significant smoking cessation rates can be achieved among Chinese smokers in a clinic-based smoking cessation service. The NRT adherence was low and low adherence was associated with a lower quit rate. Trials of interventions to improve adherence and increase quit rates are needed.
