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
backgroundIron deficiency anemia (IDA) remains a major public health concern for women of childbearing age (15-49 years) worldwide. This study aimed to analyze the global, regional, and national burden and trends of IDA in this population from 1990 to 2021, evaluate its association with socioeconomic development, and project future trends up to 2040.
methodsBased on data from the Global Burden of Disease (GBD) 2021 study, this study extracted epidemiological metrics of IDA among women of childbearing age from 1990 to 2021. Core indicators, such as prevalence rates and disability-adjusted life years (DALYs), were analyzed to assess temporal trends in disease burden. Statistical analyses were conducted to calculate the estimated annual percentage change (EAPC) and age-standardized rates (ASR). The association between disease burden and development levels was assessed using the sociodemographic index (SDI).
resultsGlobally, the age-standardized prevalence rate (ASPR) of IDA showed a declining trend, with an EAPC of -0.11 (95% confidence interval [CI]: -0.13, -0.08). Although the absolute number of DALYs increased from 18.01 million to 22.93 million, the age-standardized DALY rate decreased from 668.3 to 598 per 100,000 population, with an EAPC of -0.37 (95% CI: -0.39, -0.34). High SDI regions experienced significant reductions in IDA burden, whereas low SDI regions showed slower improvement.
conclusionAlthough the global burden of IDA among women of childbearing age has declined, regional disparities persist; high SDI regions have progressed, while low SDI regions still face a growing disease burden, underscoring the need for targeted and equitable interventions.
