Effect of a web-based intervention on the mental health of informal caregivers of the elderly: a randomized controlled trial.
Trial report in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 2 of them syntheses that pooled it.
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
backgroundIran's demographic trends indicate significant aging, with intensive caregiving linked to mental health issues among caregivers, especially during the Covid-19 pandemic. This study aimed to evaluate the impact of Mehrpishegan's web-based intervention on depression, anxiety, and stress levels among informal primary caregivers of older adults in Iran.
methodsThis study was a parallel-group, superiority, single-blinded randomized controlled trial conducted in Tehran. Eligible participants were informal caregivers with primary caregiving responsibility, access to the internet and a smart device, at least one month of caregiving experience, and the ability to use a web-based intervention. The primary outcomes were measured at baseline, 3 months, and 6 months using DASS-21. Participants with mild and moderate levels at baseline were randomized into intervention (n = 83) and control (n = 80) groups. The intervention group accessed the website, which provided structured educational content and chatrooms(psychologist-led for three months, then peer-led). Engagement was measured via session attendance, forum participation, and educational material usage. Data were analyzed using repeated measures ANOVA based on the intention-to-treat (ITT) and per-protocol approaches.
resultsOf the participants, 128 completed the final assessment at six months, resulting in an attrition rate of 20%. The intervention group showed a small decrease in depression (10.23 ± 0.80 vs. 10.48 ± 0.75, diff = 0.253; 95% CI = -0.24, 1.94), anxiety (6.70 ± 0.64 vs. 7.86 ± 0.60, diff = 1.17; 95% CI = -2.93, 0.59), and stress (13.94 ± 0.78 vs. 15.16 ± 0.74, diff = 1.22; 95% CI = -3.37, 0.92), but none of these differences were statistically significant (p > 0.05). Effect size calculations indicated small reductions in anxiety (d = -0.30) and depression (d = -0.28) at three months, though these remained below the threshold for clinical significance (|d| < 0.5).
conclusionsAlthough the web-based intervention showed some improvements in caregivers' mental health outcomes, the changes were not significantly different from those in the control group. Several challenges, including internet disruptions, voluntary participation, and the impact of the COVID-19 pandemic, may have influenced these outcomes. To enhance the effectiveness of web-based support programs, future interventions must overcome technological barriers, strengthen caregivers' digital competencies, tailor content to individual needs, and address key mental health risk factors. A more personalized and accessible approach could improve engagement and long-term benefits for caregivers.
