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
Many forms of learning, including songbird vocal learning, rely on the brain's ability to use pre-motor variation and sensory feedback to guide behavior toward a specific target or goal. In the vocal control system of zebra finches (Taeniopygia guttata) the pre-motor mechanisms of vocal variation are thought to be vested primarily in a neural pathway that includes the basal ganglia. A second circuit that includes avian analogues of mammalian pre-motor and motor cortex (the vocal motor pathway) generates the patterned structure of learned adult song. Here, we tested the ability of the basal ganglia pathway to generate pre-motor vocal variation within the spectral and temporal dimensions of zebra finch song structure. In adult birds, ablation of the basal ganglia pathway significantly reduced the spectral and temporal dispersion of individual song syllables, with the exception of syllable pitch, where the reduction was not statistically significant when compared against surgical controls. We found a similar pattern of results using longitudinal comparisons (juvenile vs adult) to isolate the contribution of the basal ganglia pathway to spectral dispersion in populations of developing song syllables--variation in syllable pitch was significantly smaller than in all other measured spectral features. The results indicate that pre-motor variation generated by the basal ganglia pathway may be sufficient to adjust vocal output toward highly acoustically dispersed targets of imitation, but suggest that complete acquisition of the pronounced variation in syllable pitch that characterizes adult song will necessitate a gradual developmental interaction between the basal ganglia and vocal motor pathways.
