A co-created randomised controlled feasibility trial of a peer-led complex oral health intervention in UK secondary schools: the RAISED In Yorkshire RiY study protocol.
Article in Pilot and feasibility studies, 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
backgroundTooth decay in secondary school children is one of the most prevalent non-communicable diseases in the UK and globally. Whilst almost entirely preventable, oral health inequalities remain a significant public health problem to reach and manage those most vulnerable. School-based prevention strategies targeted to localities with oral health inequality, and incorporating peer-to-peer interventions warrant further evaluation. These peer-to-peer interventions have a bidirectional benefit and are proposed to positively influence both the 'peer leader' and 'peer recipient'; they rely on shared cultural backgrounds and relatability to reach students that may be missed by typical healthcare professional-led interventions. This protocol describes a feasibility trial which aims to establish RAISED in Yorkshire with its peer-to-peer delivery model within the secondary school setting supported by newly qualified dentists as an effective and sustainable approach to improve oral health awareness, skills (toothbrushing) and behaviours in adolescents from underserved at-risk communities.
methodsThis is a UK school-based, assessor-blinded, parallel two-arm randomised controlled feasibility trial with a preliminary interim assessment in advance of progression to a larger scale trial in the future. The trial aims to recruit n = ~240 11-13-year-old participants and n = ~50 16-18-year-old peer leaders across five schools/colleges in West Yorkshire. The primary outcomes are related to feasibility in terms of recruitment and retention of participants, and the ability to deliver the intervention. The secondary outcomes include the oral health of participants (knowledge, attitudes and behaviour, plaque and gingival index) and process evaluation. DISCUSSION: The findings of the feasibility trial will dictate whether the project is scalable and can be delivered to multiple schools regionally and nationally. The findings will also show whether it is an effective method to provide oral health education for 11-13-year-old adolescents when delivered collaboratively by trained 16-18-year-old peer leaders.
