'Saga Stories in health talks' for health promotion in Swedish child healthcare: results from a cluster-randomised hybrid type 1 effectiveness-implementation study.
Trial report in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05237362 (An Effectiveness-implementation Hybrid Trial to Evaluate a Health Promotion Intervention Within Swedish Primary Child Healthcare), which is not on this 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.

Abstract
backgroundEarly-life interventions are essential for improving public health since lifestyle behaviours are established already in childhood. Child healthcare (CHC) plays a crucial role in this context. The 'Saga Stories in health talk' (SSiHT) material includes a flipchart with colourful illustrations to facilitate CHC nurses' routine health talks with parents and their children, and a hand-out material kit to support healthy lifestyle behaviours in the families. Our aim was to evaluate the effectiveness of the SSiHT intervention at the 5-year routine visit at CHC on parental self-efficacy (primary outcome) and children's health-related behaviours (secondary outcomes). Implementation aspects for using the SSiHT material in routine practice for health talks at the 5-year visit were simultaneously evaluated.
methodsA hybrid type 1 effectiveness-implementation design was used to evaluate the intervention in six health regions across Sweden. A cluster-randomised controlled trial was conducted to evaluate effectiveness, where 40 CHC centres (98 nurses) were randomised into two arms: use the SSiHT material in routine care (intervention), or standard care (control). Parents (n = 698) of 5-year-olds were recruited. Outcome measures were assessed using digital questionnaires before the health talk (baseline), and two months later (follow-up). Linear mixed-effect models were used to contrast differences in outcomes between groups, in accordance with the study protocol. Acceptability, appropriateness, feasibility, fidelity, and adoption were evaluated using questionnaires and checklists to CHC nurses in the intervention group.
resultsNo statistically significant intervention effects were found on parental self-efficacy to promote healthy lifestyle behaviours in their children (-0.61 score on a scale 0-160; p = 0.56), nor children's intake of vegetables, fruits/berries, and sweet drinks or screen time (p > 0.05 for all). However, CHC nurses overall reported that the SSiHT material was feasible and appropriate to use in the health talks with families, and they used it in 83% of their health talks.
conclusionAlthough the SSiHT material was well accepted by the CHC nurses, there was no intervention effect on parental self-efficacy (primary outcome) nor health-related behaviours in children when evaluated in Swedish CHC. This warrants further research to better understand how to effectively empower parents through CHC health talks.
