Role of child weight status and the relative reinforcing value of food in children's response to portion size increases.

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
objectiveFood portion size is an important determinant of intake in children. It remains unknown if children's weight status and relative reinforcing value of food (RRVF) interact with portion size to affect intake.
methodsIn a randomized crossover design, 25 normal-weight and 25 obese children, ages 8-10 years, consumed dinner once a week for 3 weeks. At each dinner, the same meal was served, but the portion size of all foods (chicken nuggets, hash browns, ketchup, green beans, brownies) and a sugar-sweetened beverage (fruit punch) varied across conditions (100, 150, and 200%). Children's RRVF was assessed using a behavioral choice task.
resultsThere was a significant main effect of portion size condition (P = 0.003) and weight status (P = 0.0005) and a nonsignificant trend for a portion size-by-weight status interaction (P = 0.108) on intake. Mean intakes across conditions (100, 150, and 200%) were 801 ± 57, 964 ± 58, and 873 ± 57 kcal for normal-weight children and 1041 ± 57, 1129 ± 57, and 1210 ± 57 kcal for obese children, respectively. Neither the main effect of RRVF status nor the condition-by-RRVF status interaction was significant (P > 0.48).
conclusionsEnvironments that offer large portions of palatable foods affect all children's intake irrespective of their weight status or how reinforcing they find food to be.
