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
backgroundRare diseases are associated with chronic progression, functional impairment, and complex care needs, requiring long-term and coordinated rehabilitation. Physical and Rehabilitation Medicine (PRM) plays a key role in maintaining functional capacity and improving quality of life; however, access to rehabilitation services remains uneven across regions.
aimThis study aims to assess the regional structural availability of PRM services across Bulgaria and to identify territorial differences in the organizational profile of rehabilitation services that may influence the potential availability of rehabilitation care for patients with rare diseases.
methodsA descriptive cross-sectional study was conducted using publicly available aggregated data from the NHIF and the National Statistical Institute as of 31 December 2024. Structural indicators included the number of outpatient and inpatient PRM healthcare facilities and PRM specialists, standardized per 100,000 population, as well as the outpatient-to-inpatient facility ratio (OFs/IFs). Hierarchical cluster analysis (Ward's method, Euclidean distance) was applied as an exploratory tool to identify similarities in regional service availability profiles.
resultsSubstantial regional differences in the structural availability of PRM services were identified. Outpatient facilities ranged from 4.46 to 6.74 per 100,000 population, while inpatient facilities ranged from 2.30 to 3.42 per 100,000 population. The OFs/IFs ratio varied between 1.30 and 2.26, indicating different organizational profiles of PRM service provision. Exploratory hierarchical clustering suggested two broad regional service profiles: one characterized by a relatively balanced distribution of outpatient and inpatient structures and another characterized by a predominance of outpatient-oriented rehabilitation services.
conclusionThe findings reveal substantial regional differences in the organization of PRM services in Bulgaria. Regions with a predominance of outpatient structures may demonstrate different capacities for delivering comprehensive rehabilitation services, particularly for patients with complex long-term needs, including rare diseases. The results highlight the need for targeted regional planning, improved integration of rehabilitation services, and policy measures aimed at ensuring equitable access to care.
