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

casesMicrodissection testicular sperm extraction (micro-TESE) was performed on five Japanese men with non-mosaic Klinefelter's syndrome (KS) and non-obstructive azoospermia in the authors' department. Here is reported the operative results and partner's clinical course for two cases where spermatozoa could be acquired. Also encountered was a man with non-mosaic KS with the partial deletion of azoospermia factor (AZF)b. Because this is rare, it is reported in detail in the context of the previous literature. This case series describes the first experience of micro-TESE by gynecologists in the current department. OUTCOME: The egg collection date was adjusted to the micro-TESE day by using the modified ultra-long method. Intracytoplasmic sperm injection (ICSI) was implemented for two men whose spermatozoa were acquired by micro-TESE, with these progressing to the blastocyst stage. Subsequently, one case conceived after the transfer of fresh embryos and a healthy baby was delivered. However, spermatozoa could not be retrieved from the man with non-mosaic KS who was harboring the partial deletion of AZFb.

conclusionThese findings suggest that ovulation induction by using the modified ultra-long method with micro-TESE and ICSI on the same day represents an effective treatment option for men with non-mosaic KS. As there are cases where AZF deletion is recognized among patients with non-mosaic KS, screening before micro-TESE is strongly recommended.
