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
backgroundMineral deficiencies are significant public health concerns worldwide, contributing to the development and progression of non-communicable diseases (NCDs). We evaluated longitudinal adequacy of mineral intakes among Iranian adults.
methodsAdult (aged ≥ 18) participants were included in the repeated cross-sectional analysis from 2006-2008 to 2018-2022. Dietary intake was assessed using a validated Food Frequency Questionnaire (FFQ). Adequacy of minerals intake, including calcium, iron, magnesium, zinc, copper, manganese, selenium, and chromium, were evaluated against the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines. Longitudinal trends of mineral intakes were evaluated using repeated measures analysis of variance in a cohort of 4384 participants (42% men; mean age 40.8 ± 12.8 years).
resultsCalcium inadequacy increased markedly from 39.6% in 2006-2008 to 68.6% in 2018-2022, with higher rates among women (74.1%) and older adults (75.0%). Iron inadequacy, mainly affecting women, increased from 14.5 to 39.1% over the same period. Although magnesium inadequacy remained high overall, it reached 34.2% in 2018-2022. In contrast, manganese intake was rarely inadequate. Zinc, copper, selenium, and chromium inadequacies showed fluctuations, but mean levels were generally closer to recommended values despite notable gender disparities.
conclusionsThe study indicates significant and worsening mineral intake inadequacies among Iranian adults, particularly for calcium and iron. Further long-term studies are needed to guide interventions, such as dietary education, food fortification, and policy measures aimed at improving micronutrient intake across diverse age and gender groups.
