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
In order to understand how sound intensity information is extracted and processed in the auditory nuclei, we investigated the neuronal excitability in the nucleus angularis (NA) of the chicken (P0-5) and the chicken embryo (E16-21). In embryos, neurons fired basically in three patterns in response to current injections: the onset pattern (19 %), the tonic pattern (52 %) and the pause pattern (29 %). After hatching, neurons fired either in the tonic pattern (83 %) or in the onset pattern (17 %). In both pre- and post-hatch periods, multiple firing neurons (tonic and pause) increased the maximum rate of rise of the action potential 2.6-fold, the fall 3.9-fold, and the maximum firing frequency 4-fold, and shifted the threshold potential to be more negative. After hatching, the firing frequency of tonic neurons reached a maximum at about 650 Hz. Application of TEA (1 mM) reduced the firing frequency, broadened action potentials and reduced the maximum rate of fall, but the threshold current was not changed. Dendrotoxin-I (DTX, 100 nM) reduced the threshold current. Application of DTX induced the onset neuron to fire repetitively. Branching patterns of auditory nerve fibres (ANFs) in NA were visualized by labelling with 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (Di-I) placed within the cochlea. Di-I placed near the apex of the cochlea labelled the ventral part of the NA, and Di-I placed in the base labelled the dorso-lateral part. Tonic neurons labelled with biocytin extended dendrites in parallel with the projection of ANFs in the nucleus after hatching. ANF activity of a limited range of characteristic sound frequencies is thought to be extracted by tonic neurons and encoded into firing frequencies proportional to the strength of the input.
