Behavioural factors associated with cigarette quitting behaviour: an analysis of cross-sectional survey data collected in three low-income South African communities.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo study the behavioural factors associated with sustained cigarette smoking cessation, and those associated with a current smoker attempting to quit, among current and former cigarette smokers living in low-income South African communities.
settingThree low-income areas in South Africa.
designIn-person surveys with structured questions that asked respondents about their cigarette smoking and quitting behaviour, sociodemographic information and behavioural attributes.
participantsCurrent smokers were eligible to participate if they had smoked at least one cigarette in the week prior to the interview (n=569). Former smokers were eligible if they had ever smoked cigarettes regularly in the past and had abstained from smoking for at least 6 months (n=106). OUTCOMES: (1) Abstinence from cigarette smoking for at least 6 months and (2) attempting to quit cigarette smoking in the past 12 months.
resultsCompared with low levels of self-control, high levels of self-control increase the odds of sustained cessation (OR=2.690, 95% CI: 2.480 to 2.917) and of making a quit attempt (OR=1.271, 95% CI: 1.254 to 1.288). Relative to low levels of stress, high levels of stress reduce the odds of sustained cessation (OR=0.938, 95% CI: 0.927 to 0.948) and of attempting to quit (OR=0.824, 95% CI: 0.666 to 1.019). Hyperbolic discounting reduces the odds of sustained cessation (OR=0.841, 95% CI: 0.822 to 0.862) while exhibiting more quitting self-efficacy increases these odds (OR=2.063, 95% CI: 1.745 to 2.439). Being impatient reduces the odds of making a quit attempt (OR=0.814, 95% CI: 0.702 to 0.943), as does a tendency to postpone important tasks (OR=0.784, 95% CI: 0.644 to 0.956).
conclusionsNon-pharmacological cessation support to low-income smokers should challenge potential lifetime quitters to practice self-control, equip them with tools to manage stress, and tackle temptations to time-discounting. Existing healthcare infrastructure should be leveraged to question people who smoke about their behavioural attributes, and to use this information to deliver behavioural support that motivates and facilitates sustained smoking cessation.
