Impact of current and previous sperm findings on outcomes of intrauterine insemination.
Article in Reproductive medicine and biology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Purpose: To examine the association between semen characteristics and outcomes of intrauterine insemination (IUI). Methods: This retrospective analysis examined 1380 IUI procedures involving 421 couples. The association of clinical pregnancy with pre- and post-wash sperm characteristics was assessed. Results: Pre- and post-wash sperm characteristics did not differ between IUI cycles that resulted in pregnancy and those that did not. When the motility of pre-wash sperm was below the normal range (<42%) established by the World Health Organization (WHO), the pregnancy rate was significantly lower. In the IUI cycles when post-wash sperm motility was below the WHO standard, pregnancy was not achieved. The frequency of improvement in post-wash sperm motility in repeated IUI cycles appeared to correlate with the success of future IUI cycles. At the fourth IUI cycle, pregnancy was not achieved unless the post-wash sperm motility was normal in at least two of three attempts. When post-wash sperm concentration was below the normal range, the woman's age did not affect the IUI outcomes. Conclusions: Sperm motility above the lower limit of the WHO criteria in post-wash semen samples is an important factor in IUI outcomes.
