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
To evaluate the effect of growth hormone (GH) supplementation on outcomes of in vitro fertilization (IVF) or Intracytoplasmic sperm injection (ICSI) for women with poor ovarian response. Relevant randomized controlled trials (RCTs) were obtained through search in several databases including PubMed, Scopus, Clinicaltrials.gov, Google Scholar, and Cochrane Library. Outcome measures included live birth rate, clinical pregnancy rate, cycle cancelation rate, number of retrieved oocytes, number of transferred embryos, total dose of gonadotropin, duration of gonadotropin treatment, and peak estradiol level. Additionally, a meta-regression analysis was carried out to determine any potential linear relationships between these outcomes and IVF success. After analyzing 18 RCTs comprising of 1870 patients, the study found that GH supplementation improved the number of retrieved oocytes [standardized mean difference (SMD), 0.65; 95% confidence interval (CI), 0.29-1.00] and transferred embryos group (SMD, 0.80, 95% CI, 0.39, 1.21) as well as peak E2 level (SMD, 1.20; 95% CI, 0.59, 1.81). While reduced the total dose and duration of gonadotropin treatment (SMD, -0.82, 95% CI, -1.25, -0.39, and SMD, -0.63, 95% CI, -1.04, -0.22, respectively). The meta-regression analysis found no linear relationship between clinical pregnancy, live birth rate, or cycle cancelation rate and the outcomes measured (p>0.1). Based on the available evidence, GH supplementation appears to improve the outcomes of IVF or ICSI in women with poor response. However, there is a need for further RCTs with larger sample sizes to determine the cost-effectiveness of adding GH to conventional protocols of IVF/ICSI for treating infertility in women with poor ovarian response.
