Association of body mass index categories with healthcare use and health expenditures in Switzerland: a cross-sectional, community-based study.
Article in The European journal of health economics : HEPAC : health economics in prevention and care, 2026. 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
backgroundIncreased body mass index (BMI) is associated with increased medical costs, but no information is available for Switzerland. We investigated the association of individual BMI categories with healthcare use and healthcare expenditures.
methodsData from an ongoing prospective, community-based study conducted in Lausanne, Switzerland. Information on healthcare use, type of insurance and deductible level were provided by the participants for period 2018-2021. Health expenditures were obtained from health insurers.
results1960 participants (64.5 ± 9.6 years, 50.4% women) had data on healthcare use. After multivariable adjustment on socioeconomic and health covariates, participants with obesity were less likely to use complementary medicines or over the counter drugs, odds ratio and (95% confidence interval): 0.74 (0.56-0.98) and 0.61 (0.44-0.85), respectively, while being more likely to be on polypharmacy [1.52 (1.05-2.20)] and benefitting from home care [2.25 (1.19-4.25)]. 907 participants (64.4 ± 9.4 years, 48.6% women) had data on health expenditures. BMI levels were positively associated with total health expenditures (median and [interquartile range]: 3740 [1717-7935], 2815 [666-6170] and 1680 [248-4975] CHF for obesity, overweight and normal weight, respectively, p < 0.001) and expenditures paid by insurance (3189 [820-7262], 2179 [0-5604] and 1019 [0-4205] CHF, respectively, p < 0.001). After multivariable adjustment, participants with obesity still presented higher total expenditures, while no difference was found for insurance-paid expenditures or participants with overweight.
conclusionPeople with obesity have higher healthcare use and higher total health expenditures than people with normal weight.
