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
The purpose of the current study was to determine the difference between heart rate variability levels before and after self-reported non-medical cannabis use within a sample of African American young adults living with cannabis use disorder. The sample included 31 self-identifying African American undergraduate students (Women = 83.87 %), with a mean age of approximately 19.71 (SD = 1.49) years. After giving consent, the participants were administered a semi-structured interview that included the Mini International Neuropsychiatric Interview (MINI) to determine cannabis use disorder (CUD) status. If a participant met the criteria for CUD, they were instructed to wear a Garmin smartwatch for three consecutive days. The Garmin smartwatch collected interbeat intervals via photoplethysmographic measurement. Participants were also instructed to complete a survey each time they smoked cannabis, a survey that asked for the start and stop times for each cannabis smoking session. Employing mixed ANOVA and Multilevel models, results suggest a significant difference in HRV levels before and after self-reported cannabis smoking. Specifically, both time and frequency domain HRV metrics are significantly lower than levels prior to smoking cannabis. Further, we see a significant increase in average heart rate from before to after cannabis smoking. The current findings identify cannabis' acute autonomic cardiac influence among individuals living with CUD. Future research should elucidate the impact of repeated cannabis exposure and their long term autonomic implications, including more cannabis ingestion modalities.
