Individual characteristics associated with changes in the contribution of plant foods to dietary intake in a French prospective cohort.
Observational study in European journal of nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeRebalancing the contribution of animal- and plant-based foods is needed to achieve sustainable diet. However, little is known concerning individual characteristics that may influence intake of plant-based foods and their changes over time. We aimed to assess changes in the contribution of plant-based foods to dietary intake over time and their association with individual characteristics.
methodsThe contribution of plant-based foods was assessed by percent energy intake provided by plant proteins in diet (PEIPP) and a score of adherence to a pro-vegetarian diet, using repeated 24-h records in 15,615 French adults participating in the NutriNet-Santé cohort study. Associations between baseline individual characteristics and changes in the two indicators over a 4-6-year follow-up were assessed using a linear mixed model.
resultsAt baseline, PEIPP and pro-vegetarian score were positively associated with age [β65+ = 0.80, 95% CI = (0.71, 0.88), β65+ = 3.30, 95% CI = (2.97, 3.64), respectively] and education [βpostgraduate = 0.23, 95% CI = (0.12, 0.34), βpostgraduate = 1.19, 95% CI = (0.75, 1.62)], while they were inversely associated with BMI class [βobesity = - 0.48, 95% CI = (0.56, 0.41), βobesity = - 2.31, 95% CI = (- 2.63, - 1.98)]. Men had higher PEIPP than women [β = 0.06, 95% CI = (0.01, 0.11)]. Pro-vegetarian score significantly increased over time [β = 0.23, 95% CI = (0.08, 0.37)]. The older the individual at baseline, the greater the decrease in the two indicators during follow-up. Pro-vegetarian score increased during follow-up for obese participants at baseline.
conclusionsThe contribution of plant-based foods was associated with several socio-demographic and economic characteristics at baseline, whereas change over time was related to age and weight status. Further analysis of individual obstacles and lever to consume plant-based foods is needed.
