Afferent input is necessary for seasonal growth and maintenance of adult avian song control circuits.

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
The neural circuits that regulate song behavior in adult songbirds undergo pronounced seasonal changes in morphology, primarily in response to changes in plasma testosterone (T). Most song nuclei have T receptors. We asked whether seasonal growth and maintenance of nuclei within these circuits are direct responses to the effects of T or its metabolites or are mediated indirectly via the effects of T on afferent nuclei. Photosensitive white-crowned sparrows were exposed to one of three treatments. (1) The neostriatal nucleus HVc (also known as the "high vocal center") was lesioned unilaterally, and the birds were exposed to long-day (LD) photoperiods and breeding levels of T for 30 d. (2) Birds were exposed to LD plus T (LD+T) for 30 d; then HVc was lesioned, and the birds were killed after an additional 30 d exposure to LD+T. (3) HVc was lesioned, and the sparrows were housed on short-day (SD) photoperiods in the absence of T treatment for 30 d. In both LD+T groups, the direct efferent targets of HVc, the robust nucleus of the archistriatum (RA) and area X, were smaller ipsilateral to the lesion. The lesion did not prevent growth of the hypoglossal motor nucleus, which does not receive direct afferent input from HVc. RA and area X were also smaller ipsilateral to the lesion in the SD birds. These results indicate that afferent input is required both for the growth of adult song circuits in response to typical breeding photoperiod and hormone conditions and for the maintenance of efferent nuclei in either their regressed or enlarged states.
