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
Duplications of Yq arm (and AZF) seems to be tolerated by fertile males, while mutations, deletions, duplications or haploinsufficiency of SHOX can originate a wide range of phenotypes, including short stature and skeletal abnormalities. We report a case of non-obstructive azoospermia in a young man with short stature, skeletal anomalies, normal intelligence and hormonal parameters. This male showed a very singular Y-chromosome aberration, consisting of a duplication of Yq and proximal regions of Yp, with a deletion of almost all PAR1 in Yptel, including SHOX. CBA- and RBA-banding and FISH-mapping with telomeric, centromeric, AZF and SHOX probes were used. These results were confirmed by array CGH, which revealed the following karyotype constitution: arr [hg19] Xp22.33 or Yp11.32p11.31 (310,932-2,646,815 or 260,932-2,596,815) ×1, Yp11.2q12 (8,641,183-59,335,913) ×2. We conclude that the haploinsufficience of SHOX may be the cause of short stature and skeletal defects in the patient, while the non-obstructive azoospermia could be related to the lack of X-Y pairing during meiosis originated by the anomalous configuration of this chromosome abnormality and large deletion which occurred in Yp-PAR1.
