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
Potential implications of gut hormones in body mass and torpor and behavioral pattern changes induced by an incremental (40 and 80%) calorie restriction (CR) in long-days (LD, summer) and short-days (SD, winter) were investigated in gray mouse lemurs. Only 80% food-deprived LD and SD animals showed a continuous mass loss resulting in a 10 and 15% mass reduction, respectively. Ghrelin levels of all food-deprived groups increased by 2.6-fold on average and remained high after re-feeding while peptide YY (PYY) levels increased by 3.8-fold only in LD animals under 80% CR. In the re-fed SD group, body mass was positively associated with ghrelin and negatively associated with PYY, while no correlations were noted in the re-fed LD animals. Plasma glucagon-like peptide-1 (GLP-1) increased by 2.9-fold only in LD food-restricted mouse lemurs and was negatively associated with the minimal body temperature. No significant correlations were reported in food-deprived SD animals. These results suggest that ghrelin, PYY and GLP-1 may be related to pre-wintering fattening mechanisms and to the modulation of torpor expression, respectively. Such observation clearly warrants further investigations, but it opens an interesting area of research in torpor regulation.
