The effect of body mass and diet composition on torpor patterns in a Malagasy primate (Microcebus murinus).

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
One of the most obvious physiological changes accompanying seasonal heterothermy in mammals is a fattening stage preceding periods of resource scarcity. This phenomenon reflects the interplay of both diet and physiology. Though the accrual of fat stores is known to be essential for overwintering in some species, the influence of diet on the physiology of torpor is not fully understood. Results from captive studies in heterothermic rodents and marsupials have indicated that when autumn diets are enriched with polyunsaturated fatty acids (PUFAs), animals receiving these diets experience deeper and more frequent torpor bouts than their counterparts receiving a control diet. Our study investigates this potential effect of dietary composition in animals that use daily torpor rather than prolonged torpor (i.e., hibernation). In so doing, we investigate the degree to which dietary effects on torpor are restricted to cold-adapted rodents and marsupials, or are a more general feature of mammalian heterothermy. We examined the effects of a PUFA diet and a control diet on the thermoregulation of one of the few species of primates known to use daily torpor: the grey mouse lemur (Microcebus murinus). Though the results of this study are largely inconclusive regarding the impact of dietary manipulations on torpor frequency and duration, we nonetheless find that the propensity of animals to enter torpor is directly influenced by age and seasonal changes in body mass, and thus reflect important physiological aspects of flexible thermoregulatory responses.
