Spatial and temporal patterns of self-harm indicators and their association with the socio-demographic index (SDI) in Iran: analysis of incidence, death, DALY, YLDs, and YLLs from 1990 to 2021 - results from the global burden of disease study 2021.

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
backgroundUnderstanding the incidence, mortality, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs) due to self-harm and analyzing their trends over time is the first step towards designing an effective suicide prevention strategy. This study aims to investigate the trend of self-harm indicators at the national level and in the provinces of Iran, by gender and age groups.
methodsIn this ecological study, the trend of self-harm indicators in Iran was examined during the period 1990 to 2021. Data were extracted from the Global Burden of Disease (GBD) database and their secondary analysis was performed with Joinpoint regression using Joinpoint 5.2 software. The spatial pattern of the indices was examined using Hot spot Analysis. The Pearson correlation coefficient was used to evaluate the correlation of indicators with the Socio-demographic index (SDI) in 1990, 2000, 2010, and 2021.
resultsAccording to estimates, the incidence, death, DALY, YLDs, and YLLs due to self-harm in Iran decreased over 32 years. On average, the annual incidence rate decreased by 0.72% (AAPC = -0.72), death by 1.39% (AAPC = -1.39), DALY by 1.44% (AAPC = -1.44), YLDs by 2.07% (AAPC = -2.07), and YLLs by 1.41% (AAPC = -1.41). The incidence trend was upward in men (AAPC = 0.25) while it was downward in women (AAPC = -1.38). A downward trend was observed in all age groups, with the greatest decrease observed in the 10-19 age group. In most provinces, the indicators decreased. The largest decrease in incidence and YLDs was observed in Kurdistan Province (AAPC = -1.42 and AAPC = -2.94, respectively) and in the three indicators of death, DALY and YLLs in Chaharmahal and Bakhtiari Province (AAPC = -2.32, AAPC = -2.52 and AAPC = -2.49, respectively). Only in Sistan and Baluchestan Province, the death rate (AAPC = 0.09), DALY (AAPC = 0.18) and YLLs (AAPC = 0.22) increased. In addition, there was a significant relationship between subnational SDIs and YLDs (r = -0.401, P = 0.025) in 2021. Between 1990 and 2021, Kermanshah and Ilam consistently appeared as hot spots for all self-harm indicators. Khuzestan also exhibited significantly elevated values, except for YLD and YLL. Conversely, Qom, South Khorasan, and Semnan were identified as persistent cold spots for mortality, DALYs, and YLL.
conclusionThe increasing trend of some indicators in men and some regions such as Sistan and Baluchestan province requires special attention and implementation of targeted intervention programs.
