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

Objective: Tooth loss in older adults was associated with an elevated risk of malnutrition, which may be compounded by limited dietary diversity. This study aimed to assess the associations between the number of natural teeth, dietary diversity (DD), and nutritional status among elderly nursing home residents. Materials and methods: This cross-sectional study involved 1,710 nursing home residents aged ≥60 years from 26 facilities. Number of natural teeth, dietary diversity score (DDS), and nutritional status were assessed. Logistic regression and mediation analysis were used to examine the associations between the number of natural teeth, DD, and nutritional status, and the mediating role of DD. Results: Participants had a mean age of 83.28 ± 8.66 years. After adjusting for confounding variables, compared with participants with 0 natural teeth, those with ≥20 natural teeth showed a positive correlation with normal nutritional status (Odds Ratio [OR] = 4.29, 95% Confidence Interval [CI]:2.26-6.15). Additionally, compared with those with a DDS of ≤5, a DDS of 8 was associated with better nutritional status (OR = 2.11, 95%CI: 1.17-3.82). DD mediated the relationship between the number of natural teeth and nutritional status ( Conclusion: Present study indicated that older adults in nursing homes with a greater number of natural teeth tended to have better nutritional status. DD played a mediating role in this association, indirectly influencing the nutritional status of the elderly. These findings highlight the critical significance of the number of natural teeth in maintaining favorable nutritional status among the elderly. Meanwhile, they suggest that DD should be incorporated into the scope of attention when focusing on the nutritional status of the elderly.
