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

objectivesThus far, some empirical studies have investigated the association between oral health and loneliness as well as social isolation. However, a systematic review and meta-analysis is lacking synthesizing this evidence. Hence, our purpose was to close this knowledge gap.

designSystematic review and meta-analysis. SETTING AND

participantsObservational studies examining the association between oral health and loneliness or social isolation were included. Disease-specific samples were excluded.

methodsWe searched three electronic databases (PubMed, PsycINFO, CINAHL), and did an additional hand search. Data extraction covered methods, sample characteristics and main findings. To evaluate study quality/risk of bias, the NIH tool was used. Study selection, data extraction and assessment of study quality were each conducted by two reviewers.

resultsSeven studies were included in our current work. Several cross-sectional studies and one longitudinal study reported an association between poorer oral health and higher loneliness as well as higher social isolation. The quality of the studies was mostly fair, with two studies of high quality. The pooled OR was 1.47 (95% CI: 1.24-1.75) among the studies with adult samples.

conclusionMost of the included studies demonstrated an association between oral health and loneliness or social isolation. There is a lack of high quality studies on these associations; in particular, future studies should use longitudinal data to clarify the directionality between oral health and loneliness or social isolation.
