1 · What the graph read from 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.

2 · The registry

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

objectivesTo assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to compare these findings with the German resident population.

methodsThis multicenter cross-sectional study recruited 544 refugees aged 3-75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications (pufa/PUFA); this data was compared to the resident population via the representative national oral health surveys).

resultsThe deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6-7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6-7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35-44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35-44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35-44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6-7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13-17-year-olds, 0.18 ± 0.6) and increased in adults (45-64-year-olds, 0.45 ± 0.8).

conclusionThe refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs. CLINICAL RELEVANCE: European countries should be prepared for the higher dental treatment needs in recent refugees, especially in children.
