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

backgroundIn some cases infertile men showed small deletions of specific genes in the Y chromosome. It had been confirmed, these deleted genes are greatly associated with spermatogenic failure. However, the frequency and the patterns of such microdeletions among infertile men are not clearly clarified.

objectiveWe sought to determine the frequency and the patterns of Y chromosome microdeletions in azoospermic and oligozoospermic infertile men in Northeast China, and try to optimize the selection of sequence tagged sites (STSs) of AZF microdeletions in multiplex polymerase chain reaction (PCR). MATERIALS AND

methods720 azoospermic and 330 oligozoospermic infertile men, from Northeast China were included in this retrospective study during May 2008 to November 2012. Semen analysis was performed according to the World Health Organization guidelines. Y chromosome microdeletions were detected by polymerase chain reaction assays. G-banding method was used for chromosome Karyotype analysis. Chi-square tests were used to compare patterns of Y chromosome microdeletions in azoospermic and oligozoospermic patients.

resultsOf 1050 infertile men, 12.95% cases had shown Y chromosome microdeletions, and 19.43% of cases showed abnormal chromosomal karyotype. Deletions in AZFc region was the most frequent 75.00%, followed by deletions in AZFb region 13.33%, AZFbc region 09.62%, and AZFa region 2.22%. All oligozoospermic patients showed presence of sY84, sY86, sY127, and sY134. Deletion of sY127 (p=0.0101) and sY157 (p=0.0043) showed significant difference between azoospermic group and oligozoospermic group.

conclusionDeletions of sY127 may relate to azoospermia while sY84, sY86, sY127 can be ignored in AZF screening for oligozoospermic patients.
