1 · What the graph read from it

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.

2 · The registry

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

BRD7 was originally identified as a novel bromodomain gene and a potential transcriptional factor. BRD7 was found to be extensively expressed in multiple mouse tissues but was highly expressed in the testis. Furthermore, BRD7 was located in germ cells during multiple stages of spermatogenesis, ranging from the pachytene to the round spermatid stage. Homozygous knockout of BRD7 (BRD7(-/-)) resulted in complete male infertility and spermatogenesis defects, including deformed acrosomal formation, degenerative elongating spermatids and irregular head morphology in postmeiotic germ cells in the seminiferous epithelium, which led to the complete arrest of spermatogenesis at step 13. Moreover, a high ratio of apoptosis was determined by TUNEL analysis, which was supported by high levels of the apoptosis markers annexin V and p53 in knockout testes. Increased expression of the DNA damage maker λH2AX was also found in BRD7(-/-) mice, whereas DNA damage repair genes were down-regulated. Furthermore, no or lower expression of BRD7 was detected in the testes of azoospermia patients exhibiting spermatogenesis arrest than that in control group. These data demonstrate that BRD7 is involved in male infertility and spermatogenesis in mice, and BRD7 defect might be associated with the occurrence and development of human azoospermia.
