Reducing depressive symptoms after the Great East Japan Earthquake in older survivors through group exercise participation and regular walking: a prospective observational study.
Observational study in BMJ open, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06390618 (Investigation of the Biopsychosocial Effectiveness of Different Exercise Trainings in Earthquake Survivors With Post-Traumatic Stress Disorder), which is not on this map. Cited by 24 papers, 1 of them a synthesis 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.

Abstract
objectivesSurvivors of the 2011 Great East Japan Earthquake have an increased risk of depressive symptoms. We sought to examine whether participation in group exercise and regular walking could mitigate the worsening of depressive symptoms among older survivors.
designProspective observational study.
settingOur baseline survey was conducted in August 2010, ∼7 months prior to the Great East Japan Earthquake and tsunami, among people aged 65 or older residing in Iwanuma City, Japan, which suffered significant damage in the disaster. A 3-year follow-up survey was conducted in 2013.
participants3567 older survivors responded to the questionnaires predisaster and postdisaster. PRIMARY OUTCOME MEASURES: Change in depressive symptoms was assessed using the 15-item Geriatric Depression Scale (GDS).
resultsFrom predisaster to postdisaster, the mean change in GDS score increased by 0.1 point (95% CI -0.003 to 0.207). During the same interval, the frequency of group exercise participation and daily walking time also increased by 1.9 days/year and 1.3 min/day, respectively. After adjusting for all covariates, including personal experiences of disaster, we found that increases in the frequency of group exercise participation (
conclusionsParticipation in group exercises or regular walking may mitigate the worsening of depressive symptoms among older survivors who have experienced natural disaster.
