Weekend Texting Screen Time and Incident Nicotine Use in Early Adolescents: Longitudinal Analysis of the Adolescent Brain Cognitive Development Study.
Article in JMIR pediatrics and parenting, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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: Adolescent nicotine use initiation remains a significant public health concern. While screen-based behaviors have been linked to substance use, few prospective studies have examined specific forms of interactive screen engagement or tested potential psychological mechanisms underlying this association. Objective: This study aimed to examine whether weekend texting screen time was prospectively associated with subsequent nicotine use initiation among early adolescents and evaluate whether negative urgency statistically accounted for part of this association. Methods: We analyzed longitudinal data from a large cohort of adolescents who were nicotine naive at baseline. Weekend texting screen time (hours) was assessed via self-report. Negative urgency, reflecting impulsive action during negative affect, was measured using the UPPS (Urgency, Premeditation, Perseverance, and Sensation Seeking) impulsivity scale. Incident nicotine use initiation was modeled using Cox proportional hazards regression, adjusting for sex, age, race, ethnicity, and household income. We evaluated whether adjustment for negative urgency attenuated the texting-initiation association and conducted a sensitivity analysis restricted to participants for whom texting assessment, negative urgency assessment, and nicotine use initiation were temporally ordered. Results: Among 5,965 nicotine-naïve adolescents followed prospectively, 239 (4%) initiated nicotine use. Greater weekend texting was associated with increased hazard of nicotine use initiation (per hour: hazard ratio [HR]=1.07, 95% CI 1.04-1.11). A 5-hour increase corresponded to an approximately 30% to 40% higher hazard of initiation. Weekend texting was positively associated with negative urgency (β=0.079; Conclusions: Greater weekend texting screen time was prospectively associated with subsequent nicotine use initiation among early adolescents. Negative urgency was independently associated with nicotine use initiation and modestly attenuated the texting-initiation association. These findings are consistent with overlapping contributions of digital engagement and affect-driven impulsivity to early nicotine risk but do not establish a causal mediating pathway.
