Randomized, controlled clinical trial of acoustic stimulation to reduce postconcussive symptoms.
Trial report in Annals of clinical and translational neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03649958 (Randomized Controlled Trials of Closed-loop Allostatic Neurotechnology to Improve Sensory Function and Pain Management After Traumatic Brain Injury), which is not on this 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.

Abstract
objectiveEffective interventions are needed to address postconcussive symptoms. We report the results of randomized, sham-controlled trial of Cereset Research™ Standard Operating Procedures (CR-SOP), a noninvasive, closed-loop, allostatic, acoustic stimulation neurotechnology previously shown to improve insomnia.
methodsMilitary service members, veterans, or their spouses with persistent symptoms (Neurobehavioral Symptom Inventory [NSI] Score ≥23) after mTBI 3 months to 10 years ago, were randomized to receive 10 sessions of engineered tones linked to brainwaves (LB, intervention), or random engineered tones not linked to brainwaves (NL, sham control). The primary outcome was change in NSI, with secondary outcomes of heart rate variability and self-report measures of sleep, mood, and anxiety.
resultsParticipants (n = 106, 22% female, mean age 37.1, 2.8 deployments, 3.8 TBIs) were randomized 1:1 to LB or NL, with no significant differences between groups at baseline. Among all study participants, the NSI declined from baseline 41.0 to 27.2 after (P < 0.0001), with gains largely sustained at 3 months (31.2) and 6 months (28.4). However, there were no significant differences between the LB (NSI declined from 39.9 at baseline to 28.2 post-intervention, 31.5 at 3 months, and 29.4 at 6 months) and NL (NSI declined from 41.5 at baseline to 26.2, 29.9, and 27.3, respectively. Similar patterns were observed for the PCL5 and PHQ-9 and there was no difference in HRV between groups.
interpretationTen hours of acoustic stimulation while resting in a zero-gravity chair improves postconcussive symptoms. However, linking tones to brain electrical activity did not reduce symptoms more than random tones. REGISTRATION: ClinicalTrials.gov - NCT03649958.
