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
backgroundThis study examined the influence of knowledge and attitudes on smoking cessation behaviors among Koreans-including both individuals who have quit smoking and those who continue to smoke-using an extended KAP (knowledge, attitude, and practice) model.
methodsData for this study were drawn from the Korean National Cancer Prevention Awareness and Practice Survey conducted between 2014 and 2023, encompassing 12,400 participants. After excluding responses lacking data on KAP questions and individuals who had never smoked, the final analytic sample comprised 4,794 participants. To evaluate the associations among knowledge (that smoking causes cancer), attitudes (regarding smoking cessation for cancer prevention), and practice (the decision to stop smoking), we employed multiple logistic regression and mediation analyses to assess both the direct and indirect effects of these variables on smoking behavior.
resultsMost participants demonstrated awareness that smoking causes cancer. In assessing the associations among knowledge, attitude, and practice, a decline in odds ratios was observed in 2023 compared with 2021. Attitudes toward smoking cessation for cancer prevention exerted a direct influence on the decision to quit smoking, with effect sizes of 0.23 in 2014, - 0.10 in 2016, 0.50 in 2018, 0.42 in 2021, and 0.40 in 2023. Furthermore, knowledge about smoking indirectly influenced the decision to quit smoking via its effect on attitudes toward cessation, with indirect effects of 0.12 in 2018, 0.10 in 2021, and 0.09 in 2023. Notably, knowledge did not directly affect practice; thus, attitudes toward smoking cessation emerged as the primary mediator between knowledge and the decision to quit smoking.
conclusionsOur findings indicate that the decision to quit smoking is significantly influenced by individuals' attitudes toward smoking. Consequently, smoking cessation policies and interventions should integrate strategies that address attitudes in tandem with knowledge and practice components among Koreans. Moreover, the gradual weakening of the relationships among knowledge, attitudes, and practices over time underscores the need to reinforce these associations through innovative smoking cessation policies.
