Randomized controlled trial of a multiple technology-based physical activity intervention for Latina adolescents: Recruitment strategies and baseline data from the Chicas Fuertes trial.
Trial report in Contemporary clinical trials, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundLatina adolescents report low levels of physical activity (PA) and high lifetime risk of lifestyle-related diseases. They also have high rates of using technology, suggesting interventions delivered through mobile devices may be effective for this population. The current paper describes recruitment methods and baseline study characteristics for Chicas Fuertes, a fully powered randomized trial of a mobile technology PA intervention.
methodsUnderactive Latina adolescents (aged 13-18) were recruited using social media and presentations at local schools and community organizations in San Diego, California. Participants were randomly assigned 1:1 to either the intervention (Fitbit, tailored texting, social media, and website) or control group. Baseline measures included demographics, psychosocial variables, and PA measured by the 7-Day Physical Activity Recall (PAR), ActiGraph GT3X+ accelerometers, and Fitbits. Baseline data were collected from 2020 to 2023.
resultsSocial media yielded the most contacts (465), but had the lowest chance of enrollment (14 %, vs. 52 % from school presentations). Participants (N = 160) were mostly second generation (68.8 %), and low income (61.8 %), but technology access was high (>99 %). Median self-reported moderate-to-vigorous PA (MVPA) using the 7-Day PAR was 120 min/week (range 0-720), and median daily steps were 5222 (IQR 359). Median MVPA measured by ActiGraphs, however, was 0 min per week. There was no correlation between the 7-day PAR and ActiGraphs (ρ=.13,p=.12). However, ActiGraph MVPA was correlated with total steps recorded by the Fitbit (ρ=.38,p<.001).
conclusionsBoth remote and in-person approaches were successful in recruiting a sample that was underactive and low income, but had high technology use.
