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 evaluate the performance and implementation of the 2018 Classification of Periodontal Diseases for periodontitis through systematic review and survey methodology. MATERIALS AND

methodsA two-part systematic review was conducted. Part 1 aimed, with descriptive statistics, to evaluate performance metrics of the 2018 Classification, including diagnostic accuracy, prognostic performance and examiner reliability. Part 2 used thematic analysis to elucidate facilitators and barriers to the implementation of the classification. A survey collected evidence of barriers, facilitators and local implementation.

resultsPart 1 of this review included 14 individual studies of moderate risk of bias. Eight studies examined diagnostic accuracy, three studies examined prognostic efficacy and three studies examined inter-/intra-rater reliability. Part 2 included 33 individual studies with data considered at high risk of bias. The survey returned 1113 responses. The thematic analysis in Part 2 led to seven findings, five related to facilitators and two concerning barriers to the implementation. Survey results showed that 78% of respondents currently use the classification, but the most common concerns relate to its complexity.

conclusionsThe 2018 Classification performs well as a classification in comparison with previous classifications. Specific identified barriers have potentially limited the comprehensive uptake of the classification.
