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: hawking of cooked foods is an important socio-economic activity. However, hawked cooked foods are prone to contamination, especially by pathogenic microorganisms. Methods: this was a cross-sectional study of 151 cooked food hawkers and 151 cooked food samples, one sample each from every respondent. Data was collected through questionnaires, observation checklists, laboratory processes, and key informant interviews. Quantitative data were analyzed using SPSS, while qualitative data were analyzed using the thematic network analysis technique. Results: adjusted multinomial logistic regression revealed increased odds of microbial contamination in cooked foods hawked by persons with primary-level education (adjusted odds ratio) AOR = 9.278, 95% confidence interval (CI) 2.292, 37.548; p = 0.003), persons earning a profit of Ksh. ≤500.00 (AOR = 4.046, 95% CI 1.825, 8.969; p = 0.001), and in areas infested with rodents (AOR = 6.386, 95% CI 1.877, 21.724; p = 0.003). However, cooked foods hawked by males (AOR = 0.338, 95% CI 0.133, 0.856; p = 0.022), persons trained on food safety (AOR = 0.216, 95% CI 0.064, 0.733; p = 0.014), persons wearing outer garments (AOR = 0.399, 95% CI 0.196, 0.812; p = 0.011), and by persons who stored their garbage in a municipal receptacle or a standard dust bin (AOR = 0.13, 95% CI 0.041, 0.410; p = 0.000) recorded reduced risk of contamination. Conclusion: hawker´s characteristics, food handling practices, and the condition of the hawking station are important determinants of microbial contamination of cooked foods hawked in Tharaka Nithi County. Targeted interventions need to be developed and implemented to prevent related foodborne diseases.
