Trends in Sodium Content of Instant Foods in Thailand, 2018-2021: Progress and Remaining Challenges.
Article in Preventing chronic disease, 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
Introduction: Excess sodium intake is a major risk factor for hypertension and cardiovascular disease. Thailand has implemented sodium-reduction strategies, including the Salt and Sodium Reduction Strategy (2016-2025), front-of-package labeling, and the Healthier Choice logo. This study aimed to describe trends in sodium content of instant foods sold in Thailand from 2018 to 2021. Methods: We conducted an analytical study using secondary data from 2 packaged-food surveys in retail stores in the Bangkok Metropolitan Region, Thailand, in 2018, 2019, and 2021 administered by the Thai Food and Drug Administration and the Low Salt Network. We applied descriptive statistics, Mann-Whitney U, Kruskal-Wallis, Wilcoxon signed-rank, and χ Results: We analyzed data for 788 products. In 2021, the median (IQR) sodium content was 1,750.0 (1,289.1-2,267.3) mg/100 g, an 11.6% decrease from 2018 (P = .02). Overall, we found significant reductions of sodium in rice porridge/soup, brand C, egg noodles, cup products, and items manufactured in Thailand and China. Conversely, among 57 identical products available in both 2018 and 2021, median sodium content did not change significantly (P = .06); 33.3% decreased, 19.3% increased, and 47.4% were unchanged. The proportion of Healthier Choice products increased from 4.5% in 2018 to 21.1% in 2021 (P < .001), including both noodles and rice porridge/soup. Conclusion: Sodium levels in instant foods in Thailand declined modestly, and Healthier Choice products increased substantially. However, most items remain above World Health Organization benchmarks, with inconsistent reformulation. Revising Healthier Choice criteria, setting mandatory sodium targets, and strengthening monitoring could accelerate sodium reduction and improve cardiovascular health.
