Cardiovascular mortality of 40-69-year-olds in Sri Lanka from 1980 to 2010: a birth cohort analysis by age and sex.
Article in BMJ open, 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
objectivesTo compare cardiovascular mortality (ischaemic heart disease (IHD), hypertensive disease (HTN) and cerebrovascular disease (CeVD)) of 40-69-year-old Sri Lankans from 1980 to 2010 by age, birth cohort and sex.
designA comparative retrospective study.
settingSri Lanka.
participants40-69-year-old Sri Lankans from 1980 to 2010. PRIMARY AND SECONDARY OUTCOME MEASURES: Cardiovascular deaths due to IHD, HTN and CeVD.
resultsMortality due to IHD increased with age but decreased with birth cohorts with time (range 3.7-390 per 100 000 population); there was a spike in the IHD mortality rates in both age groups and birth cohorts in 2000. Deaths due to HTN markedly increased after 55 years; however, mortality decreased in the younger cohorts (range 2.8-204.81 per 100 000 population). CeVD mortality linearly increased with age (range 3.3-153.3 per 100 000 population); birth cohorts of 1926-1930 and 1931-1935 had a spike in mortality among the 60-64 and 65-69 age groups, respectively. Changes were seen among both males and females; mortality rates were higher in males than in females.
conclusionsAll cardiovascular mortality rates increased with age and are higher in males than in females. Age-specific cardiovascular mortality rates were lower in the younger birth cohorts as compared with the older birth cohorts. The increase in cardiovascular deaths in Sri Lanka is due to the ageing population.
