'Pilot RCT of a new treatment for child conduct problems that have not responded to evidence-based parent training'.
Trial report in PloS one, 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
backgroundChildren with conduct problems are at high risk of persisting mental health problems, making them a priority for early intervention. Group-based parent-training is effective but with a substantial failure rate. Based on evidence on the value of involving children, we developed Reflective Interpersonal Therapy for Children and Parents, (RICAP). We report feasibility and outcomes from the first pilot trial of an intervention for children with conduct problems persisting after parent training. In contrast to most studies, we used both parent and teacher report.
methodsThe sample comprised 105 children and their parents aged 4-10 years inclusive referred to UK Child and Adolescent Mental Health Services (CAMHS) with conduct problems. All were offered the Incredible Years (IY) parent training intervention, and parents provided pre- and post-treatment measures (including CBCL, SDQ). Children still above clinical threshold after IY were randomized either to RICAP or to usual CAMHS treatment (CTAU) with follow up 8 months later. Only those randomized to CTAU could receive school-based interventions. Trial Registration Number: ISRCTN25252940.
resultsFeasibility was supported by high retention through the initial IY (102/105) and subsequent RCT phases of the study (58/70 eligible for randomization). The majority of those randomized to RICAP attended for 11/14 or more sessions, reflecting its high acceptability to both children and parents. By parent report RICAP was superior to CTAU on CBCL externalising (d = 0.32) and internalising (d = 0.42) problems, while by teacher report CTAU was superior on SDQ total problems (d = 0.32) and reactive aggression (d = 0.27).
conclusionsWe provide first evidence of the feasibility of a design in which non-responders to parent training are randomized to novel intervention or control conditions. Outcomes were different for parent and teacher reports, highlighting for future randomized controlled trials the need to attend to possible reporter and treatment context variations.
