Evaluation of the Yes to Veg! Programme, a Food Systems Approach to Increase Vegetable Exposure and Agency in Pre-School Age Children: A Quasi-Experimental 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
Children's early years food environment can influence dietary habits. We evaluated Yes to Veg! a 4-week nursery-based programme on pre-school children's vegetable exposure, consumption and agency. A quasi-experimental study in 11 nurseries (6 intervention/5 controls) located in socio-economically deprived areas of Glasgow, Scotland. Yes to Veg! delivered locally grown fresh vegetables once-per-week for children's daily nursery activities. Control nurseries received standard healthy eating recommendations. Parental pre- and post-questionnaires measured child vegetable exposure (vegetables tried from a 27-item list), consumption frequency (1 = once-per-week to 5 = everyday) and variety consumed (0 = none/1 = 1-4/2 = 5-9/3 = 10+ kinds). Qualitative comments reported by parents, nursery staff and from researcher observations were extracted for qualitative themes. From 257 parent-child dyads recruited, 57 (n = 34 intervention/n = 23 control, child mean age 51 months) completed both questionnaires. Vegetables tried [Mean(SD)] did not change between intervention [total score pre 16.7(4.5) vs 16.8(5.6) post, difference 0.19(0.6), p = 0.765] and control group [total score pre 16.4(5.3) vs 16.0(5.6) post, difference -0.39(0.57), p = 0.503]. Median pre- and post-consumption frequency in both groups was 4 (most days); the variety of vegetables consumed was higher in intervention (5-9 items) vs control (1-4 items) and these measurements didn't change between pre- and post. Vegetable agency increased in the intervention; parents said children talked more about vegetables at home (91% vs 65% control) and were willing to try vegetables at home (41% vs 34% control); emerging qualitative themes included children's engagement with vegetables, sensory interaction and programme acceptance. Yes to Veg! facilitated exposure, engagement and familiarisation to vegetables, was well implemented and received, but did not change consumption.
