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
backgroundIsolated hypogonadotropic hypogonadism (IHH) is a clinical syndrome described by failure of gonadal function secondary to defects on the synthesis, secretion, or action of the gonadotropin-releasing hormone (GnRH). The secreted glycoprotein SEMA3A binds its receptors NRP1 or NRP2 and PLXNA to participate in axonal projection, dendritic branching, synaptic formation, and neuronal migration. Deficiency in SEMA3A, NRP1, NRP2, and PLXNA1 have been related to abnormal GnRH neuron development in mice and IHH in humans.
methodsThe aim of this study was to examine the genotypic and phenotypic spectra of the NRP1, NRP2, and PLXNA1 genes in a large cohort of IHH probands from China. We screened NRP1, NRP2, and PLXNA1 variants in Chinese IHH patients by whole exome sequencing and pedigree analysis.
resultsWe identified 10 heterozygous missense variants in PLXNA1, five heterozygous missense variants in NRP1, and two heterozygous missense variants in NRP2. NRP1 variants were found only in IHH patients with defective olfaction (i.e., Kallmann syndrome, KS). In addition, 85% (17/20) of patients harbored variants in other IHH-associated genes.
conclusionOur study greatly enriched the genotypic and phenotypic spectra of PLXNA1, NRP1, and NRP2 in IHH. It may be conducive to the genetic counseling, diagnosis, and treatment of IHH with mutations in the PLXNA1, NRP1, and NRP2 genes. Furthermore, our results indicated that NRP1 were strongly linked to hearing loss.
