Comparison of Oocyte Maturation Trigger Using Follicle Stimulating Hormone Plus Human Chorionic Gonadotropin versus hCG Alone in Assisted Reproduction Technology Cycles.
Article in International journal of fertility & sterility, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe goal of this study was to investigate oocyte maturation, fertilization and pregnancy rates among infertile women, by concomitant follicle stimulating hormone (FSH) administration at the time of human chorionic gonadotropin (hCG) trigger, compared to hCG trigger alone. MATERIALS AND
methodsIn this prospective randomized controlled trial, 109 infertile women between the ages of 20 and 40 years, received gonadotropin-releasing hormone (GnRH) antagonist and fresh embryo transfer. Following the procedure, the subjects were randomly divided into two groups on the oocyte-triggering day. In the experimental group, final oocyte maturation was achieved by 5000 IU hCG plus 450 IU FSH. In the control group, however, oocyte triggering was performed by 5000 IU hCG, only. The primary outcome was clinical pregnancy and the secondary outcomes included oocyte recovery rate, oocyte maturity rate, fertilization proportion rate, fertilization rate, implantation rate and chemical pregnancy rate.
resultsFifty-four women were appointed to the group with the FSH bolus injection at the time of hCG trigger and 55 women were assigned to the hCG alone group. Women in the FSH group had a significantly higher metaphase II (MII) oocyte (7.17 ± 3.50 vs. 5.87 ± 3.19), 2 pronuclear embryos (2PNs) (5.44 ± 3.20 vs. 3.74 ± 2.30) and total embryos (4.57 ± 2.82 vs. 3.29 ± 2.13) compared to hCG alone group, respectively. Furthermore, fertilization rate (0.75 ± 0.19 vs. 0.68 ± 0.25), implantation rate (14.2 vs. 8.5%) as well as clinical (27.9 vs. 15.9%) and chemical (32.6 vs. 20.5%) pregnancy rates were higher in the FSH group, but no statistically significant difference was found (P>0.05).
conclusionCombination of FSH and hCG for oocyte triggering improves oocyte maturity and fertilization proportion rates without increasing the chance of implantation, chemical and clinical pregnancy rates (Registration number: IRCT2017082724512N5).
