Clinical characteristics and factors associated with shorter length of hospital stay among deceased COVID-19 patients in Cambodia.
Article in Multidisciplinary respiratory medicine, 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
backgroundThe length of hospital stay (LoS) among COVID-19 patients is influenced by multiple factors. This study aimed to identify factors associated with LoS among deceased Cambodian patients with confirmed SARS-CoV-2 infection.
methodsWe analyzed a total of 106 deceased patients with confirmed SARS-CoV-2 infection reported between March 11 and May 1, 2021, and publicly shared on the Ministry of Health's Facebook page. A zero-inflated Poisson regression model was used to identify factors associated with LoS. Maximum likelihood estimates, and incidence rate ratios (IRRs) were calculated, and model goodness of fit was assessed.
resultsThe mean LoS to death was 4.39 days (standard deviation, SD = 5.17). Factors associated with a shorter LoS included critical respiratory symptoms (p = .011), being dead on arrival (p < .0001), advanced age (p = .003), residence in a province (p = .004), presence of multiple chronic conditions (p = .0006), and receiving care at a non-designated COVID-19 treatment facility (p = .005). In contrast, each additional day between SARS-CoV-2 diagnosis and hospital admission was associated with an approximately 9% increase in LoS (95% CI 1.07, 1.10).
conclusionsDespite substantial efforts by the Cambodian government to control the pandemic, many COVID-19 patients died shortly after hospital admission. The findings highlight important patient characteristics and underscore the need for improved patient education, strengthened healthcare infrastructure, and enhanced public preparedness for future pandemics.
