Can we use incubators with atmospheric oxygen tension in the first phase of in vitro fertilization? A retrospective analysis.
Article in Journal of assisted reproduction and genetics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeAim of the present study was to compare two culture strategies used in our routine in vitro fertilization program.
methodsThis is a retrospective analysis. Two culture systems were used in parallel and analysed retrospectively: 1) Use of atmospheric oxygen tension (~20 %) until insemination followed by use of low (~5 %) oxygen concentration; 2) Exclusive use of low oxygen concentration. Main outcome was the utilization rate defined as the number of transferred + vitrified embryos per inseminated oocytes. Secondary outcomes were clinical pregnancy and live birth rates.
resultsA total of 402 in vitro fertilization cycles were analyzed. Demographic and clinical data of patients belonging to the two culture systems were not significantly different. Utilization rate, cumulative clinical pregnancy rate and cumulative live birth rate per cycle was similar using two different oxygen concentration compared to exclusive use of low oxygen tension (37 % versus 39 %; 30 % versus 30 %; 23 % versus 28 %, respectively).
conclusionsThe use of a culture system with atmospheric oxygen tension from recovery of oocytes until insemination followed by culture in low oxygen gives results similar to exclusive use of low oxygen concentration.
