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
Recent work indicated that co-activity of different motoneurons (MNs) in the leech can be regulated through a network that is centered on a pair of nonspiking (NS) neurons. Here, we investigate whether this effect generalizes to different types of MNs that display differential co-activity patterns in different motor behaviors: the dorsal longitudinal excitors DE-3 and the dorsal and ventral excitors MN-L. The data indicates that both motoneurons are coupled to the NS neurons through rectifying junctions that are activated when the motoneuron membrane potential becomes more negative than that of the NS, and that they exert an inhibitory synaptic potential on NS via a polysynaptic pathway. In addition, DE-3 and MN-L are linked by junctions that allow mutual excitation but the transmission of excitatory signals from MN-L to DE-3 depended on NS membrane potential. The results support the view that NS neurons can play a central role in orchestrating the co-activity of MNs during motor behaviors.
