Projected preventable cancers through full implementation of tobacco control policies in East and South-East Asian countries, 2025-2050: a modeling study.

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
Background: To estimate the number of tobacco-related cancer cases that could be prevented if countries in East and South-East Asia achieved the highest level of implementation of the WHO MPOWER policy package (Monitor, Protect, Offer, Warn, Enforce, and Raise). Methods: Based on data from Global Health Observatory and Global Cancer Observatory. We applied fixed-effects linear regression models to examine the association between changes in the national implementation of the MPOWER policies and tobacco smoking prevalence. Population Attributable Fractions (PAFs) for 13 tobacco-related cancers were calculated using Levin's formula under the scenarios of (i) continuation of the current trend, (ii) full implementation of MPOWER. The number of preventable cases (Potential Impact Fraction-PIF) was estimated using the difference in PAFs between the two scenarios. Findings: Between 2025 and 2050, 159 million tobacco-related cancer cases were projected in East and South-East Asian countries, of which 44.2 million (PAF: 27.7%; 95% CI: 25.5-29.9) attributed to current tobacco smoking, including 41.6 million among men (PAF: 42.1%, 95% CI: 39.3-44.8) and 2.6 million among women (PAF: 4.3%, 95% CI: 3.0-5.7). Full implementation of MPOWER was estimated to prevent 3.5 million (95% CI: 2.9-4.0) cancers (PIF: 2.2%, 95% CI: 1.8-2.5). After adjusting for Human Development Index (HDI) variations, preventable cancers decreased to 2.2 million (PIF: 1.4%, 95% CI: 1.2-1.6). Interpretation: Comprehensive implementation of MPOWER policies could substantially reduce the future cancer burden in East and South-East Asian countries. Funding: None.
