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.

Abstract
research questionWhile growth hormone (GH) is hypothesized to potentially enhance embryo quality, results of current basic and clinical researches remain inconclusive. This study assesses the effect of GH supplementation on embryo quality and explores the relationship between baseline insulin-like growth factor-1 (IGF-1) levels and the efficacy of GH supplementation among Chinese patients undergoing in vitro fertilization (IVF).
designA randomized controlled Open-label trial was performed with 128 women experiencing poor embryonic development in IVF. Participants were allocated to the GH group (GH + Gonadotropin-Releasing Hormone [GnRH] antagonist protocol) and the Control group (GnRH antagonist protocol). The primary outcome was the number of high-quality embryos on Day 3.
resultsPatients in the GH group required significantly lower total doses of gonadotropin (2213 ± 667 IU vs. 2573 ± 630 IU, p = 0.0058) and shorter duration of controlled ovarian stimulation (10.1 ± 1.60 days vs. 10.6 ± 1.30 days, p = 0.0488). While there was no statistically significant overall increase in the number of high-quality embryos, subgroup analysis indicated that patients with lower baseline IGF-1 levels, especially those below the lowest quartile, might show a higher rate of high-quality embryos with GH supplementation (p = 0.0488). Additionally, the fresh embryo transfer clinical pregnancy rate was numerically higher in the GH supplementation group (46.2%) compared to the control group (38.5%), although not statistically significant.
conclusionsThis study suggests that GH co-treatment may enhance ovarian responsiveness in IVF patients with poor embryo quality, thereby reducing the dosage and duration of Gonadotropin (Gn) administration. Among individuals with lower IGF-1 levels, adding GH may improve the rate of high-quality embryos, highlighting the potential benefits of personalized treatment strategies in IVF. CLINICAL
