Global burden of disease and future trends of trichomoniasis in women of reproductive age from 1990 to 2021.
Article in Journal of health, population, and nutrition, 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
purposeThis study was conducted to assess the global burden of trichomoniasis among women of reproductive age (15-49 years old) from 1990 to 2021, analyze changes in the patterns of this disease, identify regions with a high disease burden and key risk factors of trichomoniasis, provide evidence-based support for the differentiated prevention and control of trichomoniasis, and guide countries to optimize the allocation of health resources to reduce the damage to reproductive health.
methodsUsing the Global Burden of Disease (GBD) database, we first analyzed the incidence, prevalence, disability-adjusted life years (DALYs) of trichomoniasis among reproductive-age women worldwide and in five sociodemographic index (SDI) regions (low SDI, medium-low SDI, medium SDI, medium-high SDI, and high SDI), and the changes in their trends. Then, we analyzed the effect of the SDI and risk factors of 21 countries and 204 regions on the incidence and prevalence of trichomoniasis among reproductive-age women in different SDI regions. Finally, we constructed an autoregressive moving average (ARIMA) model to predict the global trends of incidence and prevalence among women of reproductive age in different regions of SDI from 2022 to 2030.
resultsThe results of this study revealed that the global incidence, prevalence, and DALYs of trichomoniasis among women of reproductive age showed a yearly increasing trend from 1990 to 2021, and that DALYs were closely associated with regional SDI levels and unsafe sex. The incidence and prevalence of trichomoniasis first decreased and then increased from 2022 to 2030.
conclusionThe global incidence and prevalence rates of trichomoniasis among women of reproductive age, measured per 100,000 people, showed a yearly increasing trend from 1990 to 2021.Therefore, preventive and control measures for Trichomonas vaginalis need to be strengthened, health expenditures need to be restructured, and the prevention and control of risk factors need to be focused on.
