Socioeconomic Determinants of Campylobacter spp. and Non-Typhoidal Salmonella spp. Infections in Ontario, Canada, 2015-2017: An Ecological Study.

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
introductionCampylobacter spp. and non-typhoidal Salmonella spp. (NTS) are major causes of enteric diseases in Ontario, Canada and worldwide. Although low socioeconomic status is generally associated with poor health outcomes, its relationship with enteric diseases in Ontario is not well known. We investigated area-level socioeconomic risk factors for reported enteric infections caused by Campylobacter spp. and NTS, commonly transmitted by food in Ontario, Canada, between 2015 and 2017.
methodsUsing negative binomial regression models, we examined the association between age- and sex-adjusted incidence rates (IRs) of laboratory-confirmed cases of Campylobacter spp. and NTS (aggregated to the forward sortation area [FSA] level), and FSA-level socioeconomic factors (median household income; percent population with bachelor's degree or higher; unemployment rate; and percent visible minorities, Indigenous peoples [as defined by Statistics Canada], total immigrants, recent immigrants and lone-parent families), adjusting for the population of the FSA from the 2016 Census.
resultsAfter controlling for the other variables in the final multivariable models, an increase in the percentage of the population with a bachelor's degree or higher and in the percentage of total immigrants in an FSA significantly increased the IRs of Campylobacter infections, while an increase in the median income and the percentage of total immigrants in an FSA increased the IRs of NTS infections.
conclusionsResults from our study may inform public health interventions to reduce the rate of infections, for example, via food safety supports relevant to communities with larger numbers of Canadian immigrants. Further individual-level investigations of the socioeconomic factors identified in this study are needed. Also, future studies should assess the mechanisms through which socioeconomic risk factors affect infection rates in different communities.
