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 and Aims: Cases of young-onset colorectal cancer (CRC) have risen substantially over the last 20 years, and physicians are increasingly harnessing the influence of celebrities to raise awareness for CRC screening. Celebrity actors Ryan Reynolds and Rob McElhenney filmed their experiences undergoing colonoscopy as part of an initiative to raise awareness for CRC screening. Herein, we assess the quality of information on TikTok regarding colonoscopies and evaluate the effect of this celebrity endorsement. Methods: Hashtags encompassing colonoscopy were searched using TikTok's algorithm, and 75 videos were considered. The DISCERN questionnaire and analytics were used to quantify the quality and popularity of each video. Results: Colonoscopy-related videos were higher in quality ( Conclusions: Using TikTok, celebrities can aid in disseminating high-quality information regarding colonoscopy and other preventative medicine practices to young adults within the new social media landscape.
