The effectiveness of mandala coloring on the psychological and physiological symptoms in adult hospitalized patients: a meta-analysis.
Synthesis in BMC complementary medicine and therapies, 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
backgroundHospitalization often imposes significant psychological and physiological demands on patients. Mandala coloring may help reduce these challenges. This meta-analysis aimed to evaluate the effectiveness of mandala coloring interventions across psychological and physiological symptoms in adult hospitalized patients.
methodsA comprehensive search was conducted using nine databases. Randomized controlled and controlled studies comparing mandala coloring with control groups were included. Data extraction was performed independently by two authors, and risk of bias was assessed using the Cochrane RoB tool. GRADE Pro software was used to assess the quality of the evidence. Standardized mean differences (SMD) with 95% confidence intervals (CIs) were pooled using RevMan (version 5.4). Subgroup analyses were performed by session frequency and duration.
resultsSeventeen studies with a total of 987 participants were included. Mandala coloring significantly reduced anxiety (SMD = - 2.16, 95% CI [-3.38, - 0.95]) and stress (SMD = - 2.45, 95% CI [-3.06, - 1.85]). Improvements were also observed in well-being (SMD = 4.51, 95% CI [0.81, 8.21]) and hope (SMD = 0.42, 95% CI [0.09, 0.75]). No significant effects were found for resilience, pain, fatigue, nausea, comfort, or vital parameters. Subgroup analyses indicated that brief (≤ 30 min) and multiple-session interventions were especially effective in alleviating anxiety. The level of evidence, as assessed using GRADE, was, however, low.
conclusionMandala coloring provides nurses and healthcare professionals with an inexpensive, low-resource, and patient-friendly method to enhance psychological well-being during hospitalization. Incorporating short, repeated sessions into routine care may strengthen resilience and patient comfort. Further large-scale and high-quality trials are required to establish standardized protocols and clarify effects on physiological symptoms.
