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
backgroundInfluencer marketing on social media is a powerful, yet under-examined, driver of youth and young adult substance use. Yet, reliably identifying influencer promotion and measuring its effects, particularly at community level, remains challenging. Influencers rarely disclose brand relationships, and conventional self-reported exposure metrics fail to capture the complex digital media environment and are vulnerable to recall and endogeneity biases. This study overcomes these limitations by employing exogenous localized measures of cigar, little cigar, and cigarillo (CLCC) influencer marketing to examine the effects of influencer messages on health behavior.
methodA corpus of over 48 million geolocated tweets was compiled using a combination of machine learning and human coding methods and integrated with retrospective data from a nationally representative survey of US individuals aged 15-21 (n = 9,555). Seven distinct metrics (including simple descriptive and network-based measures) were used to identify and quantify influential accounts that posted about CLCCs. County-level influencer tweet measures within four weeks before taking the survey were linked with the respondents' CLCC and cannabis use.
resultsMultivariate logistic regression analyses revealed that living in a county with any tweets from high-follower influencers was associated with 70% greater odds of current CLCC use (OR = 1.70) and 79% greater odds of current cannabis use (OR = 1.79). Among non-current users at baseline, potential exposure to high-follower influencers' tweets was associated with 263% greater odds of initiating current CLCC use by follow-up (OR = 3.63).
conclusionsThese findings indicate that county-level influencer marketing is associated with CLCC and cannabis use and initiation, and demonstrates spillover effects from tobacco to cannabis promotion. This work showcases a novel method for identifying social media influencers and assessing the effects of exposure to their posts on health behavior.
