Distribution of dentists in the Greater Tokyo Area, Japan.
Article in International dental journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionJapan is considered to have an overabundance of dentists; however, there are scarce data on regional inequalities in the ratio of dentists to patients. We examined these inequalities in Japan's Greater Tokyo Area - otherwise known as the Kanto region, and the world's most populous metropolitan area - by subdividing it into small- and medium-sized medical care zones.
methodsWe calculated the number of dentists per 100,000 population using the 2012 Survey of Physicians, Dentists, and Pharmacists for the three medical district tiers [primary medical care zones: municipalities (cities, towns, villages and special wards); secondary medical care zones: multiple adjacent municipalities; and tertiary care zones: prefectures]. We also estimated the influence of having a dental school in the district or an adjacent district on the number of dentists.
resultsThe number of dentists per 100,000 population was 79.2 across the whole Kanto region; the range for each type of medical care zone was as follows: 65.3-126.4 at the tertiary level; 38.0-929.6 at the secondary level; and 0-3,087.6 at the primary level. The median Gini coefficient among tertiary medical care zones was 0.16 (range 0.11-0.36). The median number of dentists per 100,000 population was 273.8 in primary medical care zones that had a dental school, 79.9 in adjacent zones, and 59.6 in other zones.
conclusionsWe identified significant inequalities in the number of dentists among the medical care zones, and the presence of a dental school had a major influence on this number.
