Impact of compulsory military service on public health: significant benefits for obese and unfit young adult men.
Article in Annals of medicine, 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
backgroundObesity and poor physical fitness are essential concerns for public health and disease prevention. Alarmingly, the prevalence of both risk factors is increasing in younger populations. We investigated what is the impact of compulsory military service on waist circumference and cardiorespiratory fitness in large sample of Finnish young men.
methodsOur study was based on a database from the Finnish Defence Forces, which includes information on 249,279 healthy male conscripts (age 19.1 ± 0.4 years.). We measured the waist circumference, and cardiorespiratory fitness (12-min running test) of conscripts in the beginning and at the end of the service and evaluated how these values differed in individuals with different baseline data.
resultsThe mean changes in waist circumference and cardiorespiratory fitness were -2.1 cm [95% confidence interval (CI): -2.2 to -1.9] and +62 m (95% CI: 57-68). Conscripts with the largest waist circumference at baseline decreased their value the most and conscripts with the poorest cardiorespiratory fitness at baseline increased their fitness the most.
conclusionCompulsory conscription benefits public health by reducing waist circumference and improving cardiorespiratory fitness of initially obese and unfit young men. Changes, if maintained, are likely to translate into lower morbidity and mortality of chronic illnesses. Interventions containing similar features as military services including increased physical activity, regular sleep and healthy eating habits could be considered in decision making to counteract the growing problem of obesity and poor physical fitness.
