The provision of cognitive behavioral therapy in Japan: an analysis using insurance claims data.
Article in BMC psychiatry, 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
backgroundCognitive behavioral therapy (CBT) is a first-line treatment for many mental health conditions. In Japan, patients can receive health insurance coverage for CBT treatment of major depressive disorder (MDD), social anxiety disorder (SAD), panic disorder (PD), obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and bulimia nervosa; however, utilization of CBT remains insufficient. This study aimed to examine the status of CBT provision for these disorders using Japanese health insurance claims data.
methodsData for April 2015-March 2022 from the Detroit Employment Solutions Corporation (DeSC) database were analyzed. The dataset included "Kempo" (salaried workers' insurance; large companies) and "Kokuho" (national health insurance; self-employed and their dependents) insurance, representing 2.8% and 12% of each insured population, respectively. Patients diagnosed with the above mental health conditions were identified, and their demographic characteristics, CBT session frequencies, session intervals, and psychotropic prescription status were evaluated.
resultsOverall, 0.50% of Kempo and 0.24% of Kokuho clients diagnosed with the relevant mental health conditions claimed insurance for CBT. Among Kempo clients, CBT was claimed by 322 (89.2%) with MDD, 8 (2.2%) with SAD, 13 (3.6%) with PD, 11 (3.1%) with OCD, 5 (1.4%) with PTSD, and 2 (0.5%) with unspecified conditions. Among Kokuho clients, CBT was claimed by 1037 (92.0%) with MDD, 11 (1.0%) with SAD, 23 (2.0%) with PD, 25 (2.2%) with OCD, 13 (1.2%) with PTSD, and 18 (1.6%) with unspecified conditions. Average intervals between MDD sessions were 34.2 days under Kempo and 71.9 days under Kokuho.
conclusionsFew patients claimed insurance for CBT, and most session intervals exceeded 1 month. The findings highlight substantial unmet medical needs in CBT provision in Japan. Medical environments that support and integrate regular CBT must be established.
