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
backgroundDysthymia, a chronic depressive disorder, poses a significant public health challenge due to its prolonged course and substantial impact on quality of life, particularly among high-risk populations such as young adults. This study aims to investigate trends in dysthymia incidence and prevalence among young adults in China from 1990 to 2021 and to project future patterns through 2026.
methodsUsing data from the Global Burden of Disease (GBD) 2021 Study, we conducted an Age-Period-Cohort (APC) analysis to assess the relative risks (RRs) of dysthymia incidence and prevalence among Chinese young adults aged 20-44 years from 1990 to 2021. Bayesian and Nordpred APC models were applied to forecast age-standardized incidence rates (ASIR) and prevalence rates (ASPR) for the next 25 years (2022-2046).
resultsBetween 1990 and 2019, both ASIR and ASPR of dysthymia exhibited a declining trend. Among females, ASIR decreased from 363.099 (95% uncertainty interval [UI]: 339.146, 387.051) per 100,000 population to 318.100 (95% UI: 296.812, 339.388), while among males, it declined from 232.757 (95% UI: 216.022, 249.492) to 208.467 (95% UI: 193.617, 223.317). Similarly, ASPR decreased from 2,072.562 (95% UI: 1,813.254, 2,331.870) to 1,795.234 (95% UI: 1,582.628, 2,007.841) for females and from 1,278.432 (95% UI: 1,116.869, 1,439.994) to 1,131.620 (95% UI: 994.059, 1,269.180) for males. However, a marked increase was observed from 2020, with 2021 rates approaching 1990 levels for both sexes. APC analysis showed that RRs for dysthymia incidence and prevalence increased with age, particularly beyond 35-39 years. More recent cohorts demonstrated lower RRs compared to earlier cohorts, whereas period effects remained relatively stable. Projections indicate a continuous rise in ASIR and ASPR from 2022 to 2046 for both sexes. Throughout the study period, dysthymia prevalence rates consistently exceeded incidence rates, with females exhibiting higher rates than males.
conclusionEnhancing early diagnostic capabilities in primary care, advancing standardized treatment strategies, improving mental health literacy through health education and social media, and implementing targeted interventions for high-risk groups-particularly young women and individuals in early adulthood-are essential for alleviating the burden of dysthymia in China and other countries with similar demographic and epidemiological characteristics.
