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

aimTo assess the prevalence and severity of periodontitis in an older adult population in Western Norway using the periodontitis definition by the recently published ACES 2018 Classification Framework. MATERIALS AND

methodsIn the present study, 1298 70-year-old subjects answered a questionnaire and underwent a full-mouth periodontal examination. The prevalence of periodontitis, stages, extents and grades was presented according to the Framework applying the 2018 periodontal classification scheme in epidemiological survey (ACES). Descriptive analyses were used, and results were expressed as percentages of the total number of observations.

resultsAccording to ACES, periodontitis was detected in 100% of the study population, and Stage II, Stage III and Stage IV were present in 21%, 75% and 4% of the individuals, respectively. The majority of periodontitis cases demonstrated generalised periodontitis and Grade B was the predominant grade in the periodontitis cases. The mean number of teeth in the study population was 25.3.

conclusionThere is a high burden of periodontitis in the present population of old individuals, and the majority of participants were classified as Stage III periodontitis. The cut-offs for interdental clinical attachment loss in the definition of periodontitis affect the estimate of cases, stages and extent of periodontitis in older age groups.
