Assisted reproductive technology in Japan: a summary report for 2015 by The Ethics Committee of The Japan Society of Obstetrics and Gynecology.
Article in Reproductive medicine and biology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 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
Purpose: The Japan Society of Obstetrics and Gynecology (JSOG) implemented an assisted reproductive technology (ART) registry system in 1986. Here are reported the characteristics and treatment outcomes of ART cycles that were registered in 2015. Methods: JSOG has requested all participating ART facilities to register cycle-specific information for all ART cycles since 2007. A descriptive analysis was performed by using the registry database for 2015. Results: In total, 424 151 cycles and 51 001 neonates (1 in 19.7 neonates born in Japan) were registered in 2015. The patients' mean age was 38.2 years (standard deviation = 4.5). Among the fresh cycles, 94 158 of 244 718 (38.5%) egg retrieval cycles were cycles with freeze-all embryos or oocytes, while fresh embryo transfer (ET) was performed in 70 254 cycles, signaling a decrease from 2014. There were 169 898 frozen-thawed ET cycles, resulting in 56 355 pregnancies and 40 599 neonates. Single ET was performed at a rate of 79.7% for fresh and 81.8% for frozen cycles and the singleton pregnancy/live birth rates were 96.9%/96.5% and 96.8%/96.4% for the respective cycles. Conclusion: The total ART cycles and live births resulting from ART has been increasing in Japan. Single ET was performed at a rate of almost 80% and ET cycles have shifted from fresh to frozen cycles.
