The Effects of Motivational Interviewing on Promoting Human Papillomavirus Vaccination Initiation and Completion Among South Asian Mother/Daughter Dyads: A Pilot Randomised Controlled Trial.
Trial report in International journal of behavioral medicine, 2025. 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
backgroundVaccination against HPV is an effective strategy for the prevention of HPV infection and cervical cancer. Nevertheless, the HPV vaccine uptake rate is low among ethnic minorities in Hong Kong. This study sought to assess the feasibility and acceptability of motivational interviewing among South Asian mother-daughter dyads and to preliminarily examine its effects on knowledge of HPV infection and vaccination, health beliefs, intention to have the daughters vaccinated, and initiation and completion of HPV vaccine series.
methodsThis was a pilot randomised controlled trial. Forty South Asian mothers with at least one daughter aged 9 to 17 years were recruited. The intervention group received a motivational interviewing intervention whereas the control group received usual care. Structured questionnaires were used to collect data on the participants' characteristics and selected outcome variables. Bias-corrected Hedges' g and rate difference together with their 95% confidence intervals were calculated to estimate the effect sizes of the intervention on the outcomes The acceptability was assessed via semi-structured interviews.
resultsA larger proportion of the daughters of the intervention group participants had received the first dose of HPV vaccine (95% [19 out of 20]) vs 0% [0 out of 20]). The intervention group showed greater improvement in knowledge at 3 months after the intervention (Hedges' g = 0.77 (95%CI:0.13-1.41)). Most interviewees were satisfied with the intervention.
conclusionThe intervention was feasible and acceptable. The intervention can help to increase South Asian mothers' knowledge and to increase the initiation of HPV vaccine series by their daughters.
