Retinal microvascular and microcirculatory responses related to cognition improvement following yoga training in patients with Parkinson's disease.

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
Purpose: To determine the relationship of retinal microcirculatory responses to cognitive function following yoga training in patients with Parkinson's disease (PD). Methods: Twenty patients with diagnosed PD were recruited, and retinal imaging was successful on 17 patients (age 71.8 ± 7.2 years old, nine females). Retinal capillary perfusion density (CPD) was imaged using optical coherence tomography angiography (OCTA), and retinal blood flow (RBF) was imaged using a retinal function imager (RFI). All patients participated in three 1-hour YogaCue or Hatha yoga classes per week for 24 consecutive weeks. Pearson correlation analyses determined the relationship between the changes in retinal microcirculatory responses and cognitive function. Results: Increased RBF was significantly related to the changes of CPD in all retinal slabs, including superficial and deeper vascular plexuses and retinal vascular network (6 mm scan, r ranged 0.58-0.83, P < 0.05). The increased RBF and CPD of superficial vascular plexus (6 mm scan) were related to the improvements (i.e., shorter time) in trail-making A performance (r = -0.66, P < 0.01 and r = -0.58, P < 0.05, respectively). In addition, the change of CPD in the retinal vascular network was related to improvement in Hopkins verbal delayed recall (r = 0.50, P < 0.05). Conclusion: This is the first study exploring the relationship between retinal microcirculatory responses to yoga exercise and cognitive function in PD patients. The synergistic effect of CPD and RBF may be developed into ocular indicators for monitoring the effect of cognitive improvement from yoga exercise in patients with PD.
