Shifts in motivation to quit cigarette smoking associated with IQOS use.
Article in Addictive behaviors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionIQOS, a heated tobacco product (HTP), is among a growing number of noncombustible nicotine delivery alternatives marketed to people who smoke combustible cigarettes and are interested in less harmful alternatives. Little is known regarding whether IQOS use and IQOS-associated effects impact motivation to quit cigarette smoking.
methodsNon-treatment-seeking adult daily smokers (n = 87) completed a within-subjects study consisting of a baseline ad-lib smoking period (days 1-5), two laboratory visits (days 6-7) involving IQOS exposure, and a two-week period where participants were instructed to switch from smoking cigarettes to using IQOS (days 8-21). Motivation to quit smoking was measured on days 1 and 22.
resultsA generalized linear model revealed a significant increase in motivation to quit smoking across the 14-day switch phase with an increase of 1.47 ladder steps (Δ=1.47, sd = 1.98, t(86) = 6.92, p < 0.0001), increasing from 5.30 to 6.80. Candidate predictors were identified through a stepwise selection procedure, which resulted in a final model with two predictors, the standardized HeatStick substitution rate (b = 0.54, (CI95% 0.13-0.95), p = 0.01) and standardized relative risk perception score (b = 0.45, (CI95% 0.04-0.85) p = 0.03),
conclusionsAmong those uninterested in quitting cigarette smoking within the next month, IQOS use was associated with increased motivation to quit. Motivation to quit smoking may not be a necessary prerequisite for promoting smoking behavior change but rather bolstered by smoking behavior change in the context of HTP use. Greater perceptions of risk reduction may ultimately aid the transition from combustible to noncombustible tobacco products.
