Effect of leuprorelin in bulbar function of spinal and bulbar muscular atrophy patients: observational study for 1 year.
Observational study in Journal of neurology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis 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
backgroundThis study aimed to investigate the effect of androgen suppression therapy using leuprorelin focused on the bulbar function of patients with spinal and bulbar muscular atrophy (SBMA).
methodsGenetically confirmed SBMA patients who consented to participate in this observational study were enrolled. Leuprorelin was subcutaneously injected every 12 weeks. Videofluoroscopic swallowing study was performed at baseline and after androgen suppression therapy for 1 year. The primary outcome measures were the changes in the vallecular residue and pyriform sinus residue. The videofluoroscopic swallowing study data were analyzed and interpreted by two experienced physiatrists.
resultsA total of 40 patients with SBMA were analyzed in this study. The inter-rater reliability testing showed good agreement for the pharyngeal residue (ICC = 0.84) and videofluoroscopic dysphagia scale (ICC = 0.75). The vallecular residue and pyriform sinus residue after swallowing 9 mL yogurt were significantly reduced (26.8 ± 22.6 to 14.6 ± 14.5, p < 0.001, 14.9 ± 16.9 to 7.6 ± 9.9, p < 0.001, respectively). The swallowing subscore of amyotrophic lateral sclerosis functional rating scale-revised improved after androgen suppression therapy (3.3 ± 0.5 to 3.5 ± 0.6, p = 0.041).
conclusionsLeuprorelin significantly reduced the pharyngeal residue in patients with SBMA after 1 year of treatment without any serious adverse events and longitudinal studies are needed to confirm these results.
