Incidence and survival of Lung Cancer: A retrospective population-based cohort (Monastir, Tunisia: 2002-2022).
Article in PloS one, 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
introductionLung cancer (LC) remains one of the most lethal malignancies worldwide. In Tunisia, LC population-level data is limited. This study aimed to estimate the incidence, mortality, trends burden and survival outcomes of LC over two decades in Monastir (Tunisia).
methodsWe conducted a retrospective population-based cohort including all LC patients diagnosed between 2002 and 2014 in the governorate of Monastir, with follow-up until 2022. Age-standardized incidence and mortality rates (ASIR and ASMR) were calculated and expressed per 100,000 Person-Years (PY). Trends were analyzed using Joinpoint regression to determine Annual Percent Change (APC). Disability-Adjusted Life Years (DALYs), Years of Life Lost (YLL), and Years Lived with Disability (YLD) were computed. Survival analysis was performed using Kaplan-Meier estimates, and multivariable Cox proportional hazards regression was used.
resultsLC ASIR per 100,000 PY was 18.37 (95% CI: 15.1-21.7), 33.63 (29.3-38.0) in males, and 4.50 (2.75-6.41) in females. ASMR per 100,000 PY was 12.33 (9.2-15.84), 24.84 (19.9-29.82) in males, and 2.0 (0.6-3.42) in females. Incidence showed a significant upward trend (APC 8.23%, 95% CI: 2.66-16.12), particularly in females (APC 17.99%, 95% CI: 9.86; 33.27). Projected ASIRs were 43.7 per 100,000 PY in 2025 (95% CI: 37.1-50.3) and 64.7 per 100,000 PY in 2030 (95% CI: 56.7-72.7). DALYs attributable to LC were 1,328 per 100,000 PY, comprising 1,198.8 YLLs and 129.2 YLDs. One-year and five-year survival rates were 43.2% (95% CI: 36.6-49.8) and 22.1% (95% CI: 17.4-26.8), respectively, with a median survival of 10 months (95% CI: 8.9-11.0). Survival was higher among females, younger patients (<65 years), and those diagnosed after 2009, with an improved median survival.
conclusionLC incidence and mortality are rising, with low survival and a substantial burden of premature mortality, highlighting the urgent need for population-based prevention programs.
