Evaluating a school-based science program that teaches the physiological effects of nicotine.
Article in Addictive behaviors, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
School-based drug prevention programs represent a widely endorsed public health goal, with an important aspect of knowledge-based curricula being education about the physiological effects of drugs. Nicotine is one of the world's most addictive substances and in this program we have used nicotine-induced mammalian-like behaviors in flatworms called planarians to successfully teach students (4th-12th grade; n = 1,616 students) about the physiological and addictive effects of nicotine. An initial study tested the change in knowledge about addictive substances in 6th-12th grade students after they completed a lab examining the effects of two concentrations of nicotine on the number of stereotypies (C-shaped spasms) planarians demonstrate in a 5-minute period of time. Lab discussion focused on developing and testing hypotheses, measurement reliability, and mechanisms of nicotine action. Surveys given pre- and post-lab experience showed that 6th grade students have significantly lower knowledge about nicotine than 7th-12th grade students (6th grade: 40.65 ± 0.78% correct, 7th-12th grade: 59.29 ± 1.71%, p < 0.001) pre-lab, but that students in all grades showed a significant increase in knowledge post-lab (p < 0.001). In 6th grade the lab was effective in improving knowledge about nicotine in urban, suburban and rural schools, p < 0.001, with students in suburban schools showing significantly greater knowledge both pre-test (urban: 37.62 ± 1.45%; suburban: 48.78 ± 1.62%; rural: 37.33 ± 0.99%; p < 0.001) and post-test (urban:60.60 ± 1.85%; suburban: 67.54 ± 1.82%; urban: 61.66 ± 1.18%; p < 0.001). A second study, modifying the lab so that the time spent observing the planarians is reduced to a 1-minute period, showed that students in both 4th and 5th grades had a significant increase in knowledge about the physiological and addictive effects of nicotine post-lab (p < 0.001).
