Tobacco industry influence on breast cancer research, policy and public opinion: scoping the Truth Tobacco Industry Documents.
Article in Tobacco control, 2026. 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
objectiveOver the last 35 years, there has been growing evidence suggesting a relationship between tobacco use and breast cancer. The tobacco industry's role in shaping research, policy and public opinion about the relationship is unknown. This study's objective is to determine if the tobacco industry-funded Council for Tobacco Research (CTR) Records and the Tobacco Institute (TI) Records, housed in the Truth Tobacco Industry Document Archive, contain documents related to internal research about breast cancer and strategies to influence the science and public opinion about breast cancer causes.
methodsWe applied the situational scoping method, in which community advocates and university researchers collaborate, to (1) identify external events considered by CTR or TI as a threat or opportunity to business interests; (2) select events for further analysis and (3) conduct social worlds/arenas mapping of industry responses to selected events.
resultsThe CTR and TI Records contained 19 719 documents with the search term 'breast cancer' ranging from the 1950s to 1998. We analysed nine events relevant to the aim of this research. CTR and TI responded to external threats, pointing out methodological problems in studies they perceived as threatening, or characterising lung cancer as misdiagnosed or metastasised breast cancer. They responded to external opportunities with promoting and funding research focusing on smoking's 'protective effects' over breast cancer, and breast cancer's genetic, hormonal and dietary causes.
conclusionThe CTR and TI Records are a rich source of documents related to tobacco industry efforts to influence breast cancer research, policy and public opinion away from any aetiologic relationship between tobacco use and breast cancer.
