Effects of 30-Day Midodrine Administration, Compared to Placebo, on Blood Pressure, Cerebral Blood Flow Velocity, and Cognitive Performance in Persons with SCI.
Trial report in Topics in spinal cord injury rehabilitation, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Individuals with spinal cord injury (SCI) at and above T6 experience impaired descending cortical control of the autonomic nervous system, which predisposes them to blood pressure (BP) disorders including persistent hypotension. Objectives: The primary aim of this investigation was to determine the effects of midodrine, 10 mg, administered daily over a 30-day period in the home environment, compared to placebo, on laboratory assessments of BP, cerebral blood flow velocity (CBFv), and cognitive performance in hypotensive individuals with chronic SCI. Methods: This prospective, randomized, placebo-controlled, double-blind, crossover trial was conducted in 15 individuals with tetraplegia. In the first 30-day period, five participants were randomized to midodrine and 10 were randomized to placebo; participants were then crossed over to the second 30-day period following a 14-day washout. Laboratory assessments of BP, CBFv, and cognitive performance were measured before and after each of the two study arms. Results: Systolic BP (SBP) was significantly increased following midodrine administration compared to placebo (116 ± 23 mm Hg vs 94 ± 16 mm Hg; Conclusion: The results suggest significant increases in SBP and diastolic CBFv without appreciable effects on cognition after 30 days of midodrine administration. Further investigation is needed to identify effective antihypotensive treatment options that not only normalize BP but also improve CBFv and cognition.
