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
Concussions remain the leading form of traumatic brain injury. Despite this, there is a paucity of pharmacologic and evidence-based treatments. The objective of this study was to investigate the benefit of Ghrelin (OXE-103) as a novel treatment for subacute concussion. The study consisted of an open-label treatment arm (OXE-103) with a nontreatment concurrent control arm receiving standard of care (SOC-only). Participants had a documented concussion, within 28 days of injury, and a Post-Concussion Symptom Scale (PCSS) of 20 or more. A total of 19 subjects completed the study: 13 treatments and 6 SOC. Treatment consisted of OXE-103 40 μg/kg twice daily by self-injection for 14 days. Main Outcome Measures were change in PCSS and Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS). Outcome measures were assessed at days 1, 4, 8, 11, 15, 21, and 44. A secondary outcome was 20% improvement on either which was considered a clinically meaningful response. We found a decrease in PCSS from baseline with OXE-103 (median -34 [interquartile range {IQR}: -44, -24]) at day 44 versus SOC (median -7 [IQR: -22, 16]) at day 44. We also found an improvement in QOLIBRI-OS from baseline with OXE-103 (median 21 [IQR: 12.5, 50]) at day 44 versus SOC (2 [IQR: -25, 20.8]) at day 44. 85% (95% confidence interval [CI]: 53, 98) of subjects treated with OXE-103 had a clinically meaningful response at day 44 on PCSS versus 33% (95% CI: 4, 78) of subjects in the SOC arm. When looking at improvement in QOLIBRI-OS, 85% (95% CI: 53, 98) of subjects treated with OXE-103 had a clinically meaningful response at day 44 versus 33% (95% CI: 4, 78) in the SOC arm. We conclude that subjects treated with OXE-103 showed improved PCSS and QOLIBRI-OS scores compared to those receiving only standard therapy. We recognize the limitations of this study, including small sample size and lack of randomization. The results indicate that OXE-103 is a potential therapeutic agent to treat patients with ongoing concussion symptoms. A larger, multicenter, randomized, placebo-controlled trial would be an important next step.
