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

objectiveTo evaluate the validity of the newly developed Oral Hygiene Ability Instrument (OHAI), created to assess the cause of any inability of older adults to perform oral hygiene, and to revise the instrument based on the results.

backgroundGood oral hygiene is among the most important prophylactic measures for oral health. This applies especially to older adults, among whom risk factors and physical and cognitive barriers are more common and can hamper oral hygiene.

methodsThe OHAI contains (I) an interview, (II) clinical examination, (III) observation of oral hygiene activities and a summarising part. In the study, 149 older adults in three groups participated: stroke, cognitive disorder and general dental patients. Inclusion criteria were to be ≥65 years old, have at least one tooth and to manage oral hygiene without assistance. For criterion validity, sensitivity and specificity were calculated using eight reference instruments. To determine construct validity, we used known group validity, factor analysis and Rasch analysis.

resultsThe criterion and construct validity of the OHAI were found to be acceptable to good. In the stroke group, balance and fine motor skills were assessed to affect oral hygiene most; in the cognitive disorder group, it was balance, coordination, spatial ability and cognitive functions. Analyses revealed that one item had no added value and that some response options were not optimal.

conclusionThe OHAI proved to be valid for the group it is intended for, with only minor revisions needed, resulting in a 32-item instrument. The OHAI could be a valuable person-centred tool in prophylactic work with older adults with failing oral hygiene.
