Association among nutrition knowledge, food frequency, and food insecurity during pregnancy.

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
backgroundPregnancy nutrition recommendations are aimed at maximizing the health of pregnant people and fetuses, but the ability of people to follow these recommendations may depend on their level of nutrition knowledge and their food security status. The aim of this study was to assess the nutrition knowledge of pregnant people in the U.S. and to explore relationships among pregnancy nutrition knowledge, food intake frequency, and food security. We hypothesized that lower pregnancy nutrition knowledge would be associated with less frequent intake of recommended foods and more frequent intake of foods not recommended. We also hypothesized that these relationships would be moderated by food insecurity. Finally, we hypothesized that people with food insecurity would be less likely to adhere to pregnancy nutrition recommendations, regardless of the nutrition knowledge level.
methodsA total of 211 participants were recruited through Cloud Research survey platform. Participants completed National Health and Nutrition Examination Survey Food Frequency Questionnaire (NHANES FFQ), Pregnancy Nutrition Knowledge Questionnaire (PNKQ), and U.S. Department of Agriculture 6-item Food Security Survey with Nutrition Security questions.
resultsLower pregnancy nutrition knowledge and food insecurity were both associated with more frequent intake of both recommended and not recommended foods. The relationship between intake of "foods to avoid in pregnancy" and food insecurity was moderated by pregnancy nutrition knowledge, with greater nutrition knowledge associated with reductions in "foods to avoid in pregnancy" and alcohol, in particular.
conclusionsPregnant people consumed adequate amounts of recommended foods, regardless of pregnancy nutrition knowledge and food security status, but both impacted intake of "foods to avoid in pregnancy". Overall, nutrition knowledge was poor among participants. A significant observation from this study was the higher alcohol consumption among the lower pregnancy nutrition knowledge and food insecure people, highlighting the necessity to address alcohol consumption during pregnancy. Pregnancy nutrition education targeting lower socioeconomic groups could help improve adherence to nutrition recommendations in pregnant people with food insecurity. This is particularly crucial for educating about foods to avoid during pregnancy and tackling the issue of alcohol intake.
