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

objectivesTo explore the level of peripheral blood immune cells in patients with different stages and grades of periodontitis. MATERIALS AND

methodsA total of 229 periodontitis patients and 36 periodontally healthy patients were included in this cross-sectional study. Individuals with systemic diseases were excluded. A periodontal examination and a complete blood cell examination were performed. The percentages of T and B cells and their subsets were analyzed via flow cytometry. Covariance and logistic regression analyses were conducted, and receiver operating characteristic curve analysis was used to assess the predictive ability of the indicators.

resultsThe white blood cell (WBC) count, absolute neutrophil count (ANC), neutrophil percentage (NEU%) and neutrophil-to-lymphocyte ratio (NLR) were greater, but the lymphocyte percentage (LYM%) was lower in the periodontitis group than in the healthy control group. Patients with severe periodontitis (Stage III and IV) presented higher WBC, ANC, NEU% and NLR than those with mild and moderate periodontitis (Stage I and II) did. Area under curve (AUC) of the ANC, NEU% and NLR for the prediction of Stage III/IV periodontitis were 0.750, 0.771, and 0.774, respectively. Compared with Grade A or B periodontitis patients, Grade C periodontitis patients had a significantly lower absolute lymphocyte count (ALC) and LYM% but higher NEU% and NLR in Grade C periodontitis. The AUC of the NLR, LYM% and NEU% for predicting Grade C periodontitis were 0.797, 0.799, and 0.793, respectively. In lymphocytes, the proportions of T and B cells were lower in Grade C periodontitis patients than in Grade A or B group. Similarly, immune regulatory cells, including B10 and Treg cells, also decreased. Conversely, the Th17/Treg ratio was greater. Moreover, the Th17/Treg ratio was most strongly correlated with Grade C periodontitis (r = 0.87), followed by Treg cells(r = -0.70) and B10 cells(r = -0.38).

conclusionsANC, NEU%, NLR and LYM% are closely correlated with periodontitis. ANC, NEU%, and NLR may serve as potential markers for Stage III/IV periodontitis. LYM%, NEU%, and NLR may serve as potential markers for Grade C periodontitis. An increase in the Th17/Treg ratio is a high-risk factor for Grade C periodontitis. CLINICAL RELEVANCE: Peripheral immune cell levels vary with the stage and grade of periodontitis and can be used to distinguish the grade and stage of periodontitis.
