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
introductionParkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons in the substantia nigra, but dopamine also plays a role in the pathophysiology of migraine.
objectiveThe aim of this study is to assess lifetime and previous year prevalence rates of headache in PD patients compared with controls. PATIENTS AND
methodsWe enrolled 101 patients (57 M and 44 W) and 101 controls (62 M and 39 W), comparable for age and gender, who underwent a semi-structured questionnaire to assess the occurrence and the features of headache, and Beck Depression Inventory (BDI).
resultsWe did not find any significant differences in the overall prevalence of lifetime and last 12-month headache between the two groups, as well as lifetime and last year tension-type headache (TTH) and migraine. Patients, especially those suffering from migraine and treated with dopamine agonists (DA), more frequently showed headache remission after the onset of motor symptoms compared to the age-related remission observed in controls (p = 0.001). Patients affected by headache were less frequently treated with DA in comparison with those without (p = 0.051). Depression of mood was more severe among PD patients with migraine than with TTH (p = 0.021). PD patients with headache exhibiting the akinetic-rigid subtype more frequently reported motor fluctuations than those presenting with tremor-dominant disease (p = 0.040).
conclusionsThe prevalence of headache in PD follows that described in the general population, but dopaminergic pathway degeneration, loss of dopamine activation on the trigeminal-vascular system, and DA treatment might favor migraine improvement and remission in PD patients.
