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

Inadequate and poor quality of diet and malnutrition are common and associated with adverse health outcomes, including morbidity and mortality, among older persons. This review aimed to establish the latest evidence from studies investigating the association between oral function and nutrition among older adults. An electronic search of MEDLINE using PubMed for literature published in English between March 2018 and March 2021 was conducted, and 27 papers were identified. The selected studies comprised 23 observational studies (17 cross-sectional and 6 longitudinal studies) and 4 interventional studies. Most of the observational studies demonstrated the following associations in older adults: older adults with poor oral function are likely to have poorer dietary intake and poorer nutritional status, and malnourished older adults are likely to have poorer oral function. The results of the intervention studies demonstrated that the combination of prosthodontic treatment and dietary counseling is more effective for improving dietary intake and nutritional status in older persons with tooth loss than the prosthodontic treatment alone. Our review confirmed that a relationship exists between oral function and nutrition and revealed the need for additional high-quality studies investigating comprehensive oral function, rather than a single aspect of oral function, with regard to nutritional status.
