Risk factors for COVID-19 infection and hospitalization, a population based case-control study from eastern Iran.
Article in IJID regions, 2023. 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
Objectives: Investigating the factors associated with COVID-19 infection and its severity can be a major element in controlling the pandemics. This study aims to assess risk factors of COVID-19 infection and factors associated with hospitalization of COVID-19 cases. Methods: In this case-control study, 416 confirmed COVID-19 cases based on the polymerase chain reaction test and 535 controls were selected from the urban and rural areas of Sistan-region-East of Iran. Results: Cases had a lower frequency of hypertension than controls (12.3% vs 18.3% respectively, Conclusion: Although age was expected to be a risk factor, the observed protective effect of hypertension should be considered with caution.
