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

aimsTo investigate whether restoring serum vitamin D levels in a population requiring supplementation affects matrix metalloproteinase-9 (MMP-9) levels in the gingival crevicular fluid (GCF) of individuals with periodontal health, gingivitis and periodontitis. MATERIALS AND

methodsThis prospective cohort study enrolled 101 participants with vitamin D deficiency, including those with periodontitis (34) and gingivitis (34) and healthy individuals (33). The periodontal status was evaluated using radiographic and clinical assessments of probing depth, clinical attachment loss, gingival index and plaque index. The analysis of MMP-9 levels in the GCF collected from the same dental sites was performed at baseline and 1 month post supplementation.

resultsAfter 1 month of vitamin D supplementation, a significant decrease in GCF MMP-9 levels was observed across all groups, with the most notable reduction observed in the periodontitis group. The healthy group exhibited the highest percentage reduction at 47%. Linear regression analysis confirmed that changes in vitamin D levels and pocket depth influenced MMP-9 alterations in the GCF.

conclusionsRestoration of vitamin D levels in vitamin D-deficient patients to the recommended average level (30 ng/mL), according to established guidelines, led to decreased MMP-9 levels in individuals with different periodontal statuses (healthy, gingivitis or periodontitis), potentially mitigating periodontal risks.
