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

backgroundWith the trend toward late marriages and late childbearing, cryopreservation of oocytes for fertility preservation is attracting attention as a method to counteract the declining birthrate.

objectivesTo examine the impact of social oocyte cryopreservation on local communities by assessing the significance of government assistance for cryofreezing and capturing the participants' subsequent feelings regarding this assistance.

designDescriptive study.

methodsA prospective study was conducted on city-dwelling women <35 years old attending monthly seminars on oocyte retrieval/cryopreservation to whom the study concept was explained. Egg collection and storage management costs were free for 3 years after the project completed, and subsequent actual storage costs were borne by the individuals. After oocyte retrieval, we conducted a questionnaire on oocyte cryopreservation and administrative assistance.

resultsOf the 62 seminar participants, 2 became pregnant naturally without oocyte retrieval. Oocytes were retrieved in 34 women (average age: 32.8 years, number of oocytes obtained: 8.3), among whom 4 subsequently became pregnant and gave birth through natural pregnancy or artificial insemination, and 1 became pregnant and gave birth using frozen oocytes. In a follow-up questionnaire given to these 34 subjects, all responded that they were glad to have oocyte cryopreservation, but 23 subjects (67.6%) answered that they could not perform cryopreservation without financial assistance. Twenty-five participants (73.5%) wanted to try to conceive without using frozen oocytes as a post-cryopreservation plan.

conclusionsAs a countermeasure against the declining birthrate, oocyte cryopreservation and associated workshops that can provide the information and education needed to conduct this task in a "planned" manner may be useful in providing women with additional reproductive options. Financial assistance will also be required to offer this service to the women who need it.
