HABIT Efficacy Trial Intervention Improves Elements of General and Disease-Specific Quality of Life in Youth With Sickle Cell Disease.
Trial report in Pediatric blood & cancer, 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
backgroundWhether interventions to improve hydroxyurea adherence in youth with sickle cell disease (SCD) also improve health-related quality of life (HRQoL) has not been determined. We prospectively examined changes in generic and disease-specific HRQoL over a 12-month period in youth who participated in "Hydroxyurea Adherence for Personal Best in Sickle Cell Treatment (HABIT)" randomized controlled multi-site efficacy trial. The HABIT intervention was led by community health workers and augmented by tailored text message reminders.
methodsImprovements in generic and disease-specific HRQoL were secondary HABIT outcomes. Intervention efficacy and sustainability were measured as changes in HRQoL from Months 0 to 9 and from Months 9 to 12 of the trial, respectively. Data were analyzed for within-group and between-group changes.
resultsFifty youth, 24 assigned to intervention and 26 to the control group, mean age of 13.3 ± 1.9 years, participated in the trial. There were no differences between groups at study entry. At Month 0, total generic and disease-specific HRQoL scores were 71.2 ± 15.6 and 62.7 ± 19.0, respectively. At 9 months, compared to controls, the intervention group significantly improved generic HRQoL total score (p = 0.04) and two subscales (emotional, p = 0.03, and social, p = 0.01), and one disease-specific HRQoL subscale (treatment, p = 0.006). HRQoL improvements were not sustained at 12 months.
conclusionsFindings of this study contribute to the evolving understanding of the impact of interventions to improve hydroxyurea adherence on HRQoL in youth with SCD. Further research directed to enhancing intervention sustainability is needed to maintain hydroxyurea adherence and HRQoL improvements to reduce health disparities for youth with SCD.
