1 · What the graph read from it

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.

2 · The registry

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

backgroundLong-lasting insecticidal nets (LLINs) are essential for malaria prevention, yet consistent use remains suboptimal. This study assessed LLIN use and associated factors in Thailand and Myanmar across diverse transmission contexts.

methodsWe analyzed cross-sectional data from 13,459 individuals attending malaria service points in three districts in Thailand and two townships in Myanmar (2017-2024). LLIN use was categorized as daily, intermittent, or non-use. Logistic regression identified factors linked to non-regular use in each country. A directed acyclic graph (DAG) illustrated hypothesized causal pathways.

resultsAmong 3,062 participants in Myanmar, 16.9% reported intermittent or non-use. Higher odds were observed among individuals aged 5-14 years (aOR = 1.87, 95% CI: 1.29-2.75), 15-34 years (aOR = 3.42, 95% CI: 2.07-5.67), and ≥ 35 years (aOR = 4.42, 95% CI: 2.50-7.86), Rakhine ethnicity (aOR = 3.54, 95% CI: 2.76-4.57), residence in Paletwa (aOR = 20.9, 95% CI: 5.29-109), uncertain malaria history (aOR = 8.03, 95% CI: 3.61-18.4), and Plasmodium falciparum infection (aOR = 2.87, 95% CI: 2.02-4.06). Among 10,397 participants in Thailand, 31.2% reported intermittent or non-use. Significant factors included older age (aOR = 2.73, 95% CI: 2.07-3.62 for 15-34 years), male sex (aOR = 1.73, 95% CI: 1.56-1.91), agricultural occupation (aOR = 1.42, 95% CI: 1.04-1.95), residence in Bannang Sata (aOR = 17.9, 95% CI: 14.4-22.4) or Saba Yoi (aOR = 34.4, 95% CI: 23.3-52.3), P. falciparum (aOR = 3.61, 95% CI: 1.71-7.78), P. vivax (aOR = 2.74, 95% CI: 2.38-3.17), and lower odds with uncertain malaria history (aOR = 0.49, 95% CI: 0.35-0.68).

conclusionNon-regular LLIN use was common and linked to demographic, occupational, and clinical factors. Context-specific strategies are needed to improve adherence and support malaria elimination goals.
