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
Live-imaging of axonal cargoes within central nervous system has been a long-lasting interest for neurobiologists as axonal transport plays critical roles in neuronal growth, function, and survival. Many kinds of cargoes are transported within axons, including synaptic vesicles and a variety of membrane-bound and membrane-less organelles. Imaging these cargoes at high spatial and temporal resolution, and within living brains, is technically very challenging. Here, we describe a quantitative method, based on customized mounting chambers, allowing live-imaging of axonal cargoes transported within the maturing brain of the fruit fly, Drosophila melanogaster. With this method, we could visualize in real time, using confocal microscopy, cargoes transported along axons. Our protocol is simple and easy to set up, as brains are mounted in our imaging chambers and ready to be imaged in about 1 h. Another advantage of our method is that it can be combined with pharmacological treatments or super-resolution microscopy.
