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

Honeybees, Apis mellifera, who show temporal polyethism, begin their adult life performing tasks inside the hive (hive bees) and then switch to foraging when they are about 2-3 weeks old (foragers). Usually hive tasks require little or no flying, whereas foraging involves flying for several hours a day and carrying heavy loads of nectar and pollen. Flight muscles are particularly plastic organs that can respond to use and disuse, and accordingly it would be expected that adjustments in flight muscle metabolism occur throughout a bee's life. We thus investigated changes in lifetime flight metabolic rate and flight muscle biochemistry of differently aged hive bees and of foragers with varying foraging experience. Rapid increases in flight metabolic rates early in life coincided with a switch in troponin T isoforms and increases in flight muscle maximal activities (V (max)) of the enzymes citrate synthase, cytochrome c oxidase, hexokinase, phosphofructokinase, and pyruvate kinase. However, further increases in flight metabolic rate in experienced foragers occurred without additional changes in the in vitro V (max) of these flight muscle metabolic enzymes. Estimates of in vivo flux (v) compared to maximum flux of each enzyme in vitro (fractional velocity, v/V (max)) suggest that most enzymes operate at a higher fraction of V (max) in mature foragers compared to young hive bees. Our results indicate that honeybees develop most of their flight muscle metabolic machinery early in life. Any further increases in flight metabolism with age or foraging experience are most likely achieved by operating metabolic enzymes closer to their maximal flux capacity.
