Effectiveness of corifollitropin alfa used for ovarian stimulation of poor responder patients.
Article in International journal of women's health, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses that pooled 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.
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 evaluate the efficiency and efficacy of corifollitropin alfa (follicle-stimulating hormone-carboxy terminal peptide) in the treatment of poor responder patients.
methodsA total of 85 poor responder patients with a mean age 40.2±3.9 years entered our assisted fertilization program. The patients were prospectively randomized into two groups based on the ovarian stimulation regimen used: group A (study group) (n=42) received clomiphene citrate and corifollitropin alfa for the first 7 days of stimulation followed by recombinant follicle stimulating hormone (rFSH) in a gonadotropin-releasing hormone antagonist protocol, and group B (control group) (n=43) received clomiphene citrate and a daily injection of rFSH in a gonadotropin-releasing hormone antagonist protocol. We analyzed the stimulation outcome, the number of retrieved oocytes, cleaving embryos, and pregnancy and implantation rates as well.
resultsComparable results were observed between the two groups in terms of demographic data, stimulation outcome, and the number of canceled cycles. There were no differences evident between groups A and B with respect to the number of retrieved oocytes (3.0±0.8 and 2.7±0.7, respectively) and the number of cleaving embryos (1.8±0.6 and 1.7±0.7, respectively). Higher, though not statistically significant, differences were observed in favor of group A compared to group B in terms of pregnancy rate per cycle (19% and 16.3%, respectively), pregnancy rate per transfer (21.6% and 17.9%, respectively), and implantation rate (14.7% and 13.4%, respectively). Also, miscarriage rate was similar between patients treated with corifollitropin alfa and those treated with daily rFSH injection (12.5% and 14.2%, respectively).
conclusionThe results show that ovarian stimulation with corifollitropin alfa appears to be as efficacious and efficient as daily injection rFSH regimen to treat patients with poor ovarian response.
