1 · What the graph read from it

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.

2 · The registry

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

objectiveThe objective of this study was to examine objective (ghrelin and peptide YY [PYY]) and subjective appetite measures following 21-day high and low eating frequency (EF) interventions among healthy adults.

methodsIn the randomized crossover trial (Frequency of Eating and Satiety Hormones [FRESH] study), participants completed two eucaloric 21-day study periods of low (3 meals/day) and high (6 meals/day) EF with a 14-day washout period. Self-selected foods and total energy consumed were identical in both arms. On day 21 of each period, participants completed a 7-h clinic visit with meals provided according to assigned EF. Postprandial plasma ghrelin and PYY concentrations were assessed through serial blood draws (hourly), and self-reported appetite ratings were collected every 30 min.

resultsFifty participants were recruited and completed the trial (mean age, 32 years, 78% women, and 60% non-Hispanic White). High EF resulted in smaller changes in postprandial ghrelin and PYY concentrations compared to low EF, with significant area under the curve differences between groups (p value for ghrelin = 0.03; p value for PYY < 0.001). Similar patterns were found in self-reported hunger, desire to eat, and fullness. Differences in postprandial PYY were greater among participants with overweight/obesity or high body fat percentage.

conclusionsHigh EF led to smaller changes in objective and subjective appetite measures, suggesting that small frequent meals may lead to blunted satiety and less optimal appetite regulation.
