Intracytoplasmic morphologically selected sperm injection outcomes: the role of sperm preparation techniques.
Article in Journal of assisted reproduction and genetics, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
purposeTo compare the results of intracytoplasmic morphologically selected sperm injection (IMSI) between cycles in which the swim-up (SUP) or the density gradient centrifugation (DGC) techniques were used for sperm preparation.
methodsWe evaluated 70 IMSI cycles performed in women with age ≤ 37 years, undergoing IMSI as result of male factor. The couples were divided into two groups: DGC group (n = 26) and SUP group (n = 44). The groups were compared with regard to IMSI outcomes.
resultsThere were no significant differences between SUP and DGC groups regarding the number of follicles, oocytes, mature oocytes, oocyte yield and mature oocyte rate. Fertilization rate and high-quality embryos rate on day 5 of development were similar between SUP and DGC groups. Implantation, pregnancy and miscarriage rates were not statistically different between SUP and DGC groups (28.8 vs 33.3 %, 46.2 vs 57.1 % and 8.3 vs 4.2 %, respectively).
conclusionsBoth the SUP and the DGC techniques recover improved sperm fractions and result in similar IMSI outcomes. Further randomized trials analyzing both the quality of sperm through MSOME and the IMSI outcomes are needed to elucidate the role of sperm preparation techniques and morphology on IMSI outcomes.
