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

Trophocytes and fat cells in honeybees (Apis mellifera) have served as targets for cellular senescence studies, but mitochondrial energy utilization with advancing age in workers is unknown. In this study, mitochondrial energy utilization was evaluated in the trophocytes and fat cells of young and old workers reared in a field hive. The results showed that (1) mitochondrial density increased with advancing age; (2) mitochondrial membrane potential (∆Ψm), nicotinamide adenine dinucleotide oxidized form (NAD(+)) concentration, adenosine triphosphate (ATP) concentration, and NAD(+)/nicotinamide adenine dinucleotide reduced form (NADH) ratio decreased with advancing age; and (3) the expression of NADH dehydrogenase 1 (ND1), ATP synthase, and voltage-dependent anion channel 1 (VDAC1) increased with advancing age, whereas ND1 and ATP synthase did not differ with advancing age after normalization to mitochondrial density and VDAC1. These results show that the trophocytes and fat cells of young workers have higher mitochondrial energy utilization efficiency than those of old workers and that aging results in a decline in mitochondrial energy utilization in the trophocytes and fat cells of worker honeybees.
