Lock and Protect, Reducing Access to Adolescent Means of Suicide: A Pilot Feasibility Study.
Article in Academic emergency medicine : official journal of the Society for Academic Emergency Medicine, 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
backgroundProviding lethal means counseling to caregivers is an underutilized component of emergency department (ED)-based suicide prevention. We assessed the feasibility and acceptability of Lock and Protect, a web-based lethal means counseling decision aid, among caregivers of adolescents who presented to the ED for self-injurious and/or suicidal thoughts and behaviors.
methodsWe conducted a pilot feasibility study of caregiver-adolescent dyads in a pediatric ED. Adolescents were 13-17 years old with current suicidal ideation, suicide attempt, or non-suicidal self-injury. Caregivers received the Lock and Protect intervention plus usual care while their child was in the ED. Feasibility was measured via enrollment rates, duration of time caregivers interacted with Lock and Protect, and tool completion rates. Caregiver acceptability was measured with the Ottawa Acceptability Scale. Follow-up assessments measured changes in home storage at 2- and 4-weeks after enrollment.
resultsOf 47 caregivers screened and eligible, 40 enrolled (85.1%), of whom 39/40 and 1/40 reported home access to medications and firearms, respectively. Caregivers found Lock and Protect respectful of their family values about medications (100%) and firearms (97.5%). Almost all caregivers (95.0%) reported the length was "just right" and 92.5% reported the amount of information was "just right". All caregivers completed the tool in the ED, using it for a mean of 8 min (SD = 3.4 min). All would recommend the tool to others. Ottawa Acceptability Scale scores demonstrated that 95.0% of caregivers found the options in Lock and Protect realistic, and 97.5% found the tool useful for changing home medication access. Follow-up was completed for 77.5% of caregivers, with 20/31 (64.5%) reporting safer home storage of medications.
conclusionsLock and Protect, a web-based lethal means counseling decision aid, was feasible to administer in the pediatric ED and acceptable to caregivers of adolescents at risk for suicide.
