Spatial and spatio-temporal analysis of cancer mortality in Iran: gender disparities and implications for health policy.
Article in Preventive medicine reports, 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
Objectives: Cancer mortality, particularly for gender-specific cancers, has increased in Iran and other developing countries, highlighting notable disparities in regional trends and patterns. This study examines geographical and temporal trends in cancer mortality from 2017 to 2019. Methods: We analyzed data from Iran's Ministry of Health's death registration system, focusing on populations of 11,807 females and 14,450 males in 2017; 3133 females and 4439 males in 2018; and 4799 females and 6624 males in 2019. We employed spatial statistical methods, including Anselin Local Moran's I and Hot Spot Analysis (Getis-Ord Gi*), alongside techniques such as Mean Center, Standard Distance, and Geographic Information Systems to evaluate cancer mortality at the township level. Results: Between 2017 and 2019, cancer mortality rates among women declined from 44.9 % to 42.0 %, while rates among men increased from 55.0 % to 57.9 %. The epicenter of mortality shifted from central regions in 2017 to western regions in 2018, then to eastern regions in 2019. The standard deviation ellipse indicated a transition in cancer mortality distribution from a northwest-southeast alignment in 2017 to predominantly western and eastern orientations in subsequent years, with varied hotspot patterns across Iran. Conclusions: The study highlights rising cancer mortality rates, particularly among men and premenopausal women, underscoring the need for targeted public health interventions and improved medical infrastructure to enhance prevention and treatment efforts.
