Potential impact of e-cigarettes on life-years lost from conventional smoking in Ukraine, a replication study.
Article in Central European journal of public health, 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
objectivesSmoking remains a significant public health concern in Ukraine. Recent efforts to combat smoking have shown some progress, but Ukraine's current approach largely overlooks the potential benefits of harm reduction strategies. Concurrently, the use of e-cigarettes has been on the rise among Ukrainian adults. Our study aims to estimate the potential impact of e-cigarettes on reducing the mortality rate associated with cigarette smoking in Ukraine.
methodsWe conducted a replication study using a dynamic population simulation model initially developed for the US. We ran simulations for 210 e-cigarette scenarios, varying assumptions on how e-cigarettes may affect smoking behaviour and health outcomes. A sensitivity analysis was performed to test the robustness of the results.
resultsA substantial majority of e-cigarette scenarios (88.10%) resulted in positive life-years saved (LYS). The LYS ranged from -1.13 to 13.11 million, with a median of 3.17 million, accounting for 4.55% of the total life-years lost (LYL) due to smoking. Among the most plausible e-cigarette scenarios, the LYS varied from 2.73 to 4.88 million (3.92% to 6.99% of LYL due to smoking). Furthermore, these scenarios demonstrated that the long-term smoking prevalence would stabilize at around 5.56-6.40%.
conclusionsOur simulation analysis demonstrates the potential of e-cigarettes to significantly reduce the burden of smoking in Ukraine. Most e-cigarette scenarios result in positive LYS, while scenarios with negative LYS are unlikely. These findings support the idea that the benefits of e-cigarettes outweigh potential harm, aligning with previous studies in other countries.
