Comparison of Clinical Characteristics and Spermatogenesis in CHH Patients Caused by PROKR2 and FGFR1 Mutations.
Article in Reproductive sciences (Thousand Oaks, Calif.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
A retrospective study was conducted to investigate the effect of gonadotropin or pulsatile gonadotropin-releasing hormone (GnRH) therapy on spermatogenesis in congenital hypogonadotropic hypogonadism (CHH) patients with PROKR2 (prokineticin receptor 2) or FGFR1 (fibroblast growth factor receptor 1) mutations. Clinical features, gonadotropin levels, testicular volume (TV), and sperm concentration in response to gonadotropin and pulsatile GnRH therapy were compared between groups with PROKR2 and FGFR1 mutations. Twelve patients with PROKR2 gene mutation and fourteen patients with FGFR1 gene mutation were included. The incidence of cryptorchidism in PROKR2 and FGFR1 groups was 16.7% and 50%, respectively (p = 0.110). The baseline TV in the PROKR2 group was larger than that in FGFR1 group (2.0 vs. 1.63, p = 0.047). The initial LH, FSH, and testosterone levels were similar between the two groups. Based on the analysis of achieving spermatogenesis using Kaplan-Meier and log-rank tests, the PROKR2 group demonstrated shorter period of seminal spermatozoa appearance than the FGFR1 group (χ
