The risk of Parkinson's disease in women who underwent hysterectomy before the age of menopause.

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
Introduction: Parkinson's disease (PD) is the second most common neurodegenerative aging disorder. Oestrogen has been shown to have a neuroprotective effect against PD in animal models.This study aimed to detect the risk of PD in women who underwent hysterectomy before the age of menopause. Material and methods: Seventy-six women with PD (study group) were recruited for this retrospective study and compared to 80 controls. Collected data included the education level, smoking, age of menopause, type of menopause (natural or surgical), past surgical history of hysterectomy, type of hysterectomy (hysterectomy only or hysterectomy with oophorectomy [unilateral, bilateral]), and use of postmenopausal oestrogen replacement therapy. The collected data were analysed to detect the risk of PD in women who underwent hysterectomy before the age of menopause. Results: The odds ratio (OR) and relative risk (RR) of PD was significantly higher after surgical menopause in the study group (30 [39.5%]) compared to controls (17 [21.25%]), (OR 2.4 [95% CI: 1.19-4.8]; Conclusions: The risk of PD increased in women who underwent hysterectomy and bilateral oophorectomy before the age of menopause, and the risk of PD did not increase whether the menopause, either natural or surgical, occurred before 48 years of age.
