1 · What the graph read from 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.

2 · The registry

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

Background: Idiopathic cervical dystonia (CD) affects more female than male patients. This sex-based influence on the clinical manifestation of CD may also affect outcomes after long-term BoNT therapy. Methods: To analyze the potential differential influence of sex on the efficacy of BoNT therapy, a cross-sectional study was conducted with 135 female and 85 male patients with idiopathic cervical dystonia. Demographic and treatment-related data were extracted from patient charts. The 24-item Cervical Dystonia Questionnaire (CDQ24), patients' self-assessment of CD severity (PAS), and the TSUI score were used as outcome measures. On the day of recruitment, blood samples were collected to analyze neutralizing antibody (NAB) formation using an ELISA, with confirmation by the mouse hemidiaphragm assay (MHDA) test. Results: Male patients had significantly ( Conclusion: This reanalysis of previously published data reveals that female and male patients in this cohort were treated and responded differently to long-term BoNT therapy, a discrepancy that remained unnoticed by their treating physicians over more than 10 years of treatment.
