Diagnostic accuracy of bone-related biomarkers on peri-implantitis: potential of A-proliferation-inducing ligand.

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.
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
objectiveTo study the biomarker profile in peri-implant crevicular fluid (PICF) of A proliferation-inducing ligand (APRIL), receptor activator of nuclear factor κβ (RANKL) and interleukin (IL)-23, in healthy, periimplant mucositis and peri-implantitis sites, and to explore their diagnostic accuracy on periimplantitis (PI) diagnosis. MATERIALS AND
methodsAn exploratory cross-sectional study was conducted. Sociodemographic and clinical were recorded. Implant diagnosis was made based on the latest classification consensus. PICF samples were collected with paper strips from healthy, mucositis and PI implants. The biomarkers were analyzed by Luminex assay. The diagnostic accuracy was determined through sensitivity, specificity, predictive values (PV), and receiver operating characteristic (ROC) curves.
resultsOverall, 54 patients were recruited; 17 were healthy implants, 19 with mucositis and 18 have PI. RANKL and APRIL levels in PICF were significantly increased in PI implants compared to healthy implants (p < 0.001 and p = 0.005). IL-23 did not present differences between groups (p > 0.05). Positive correlations between PICF-RANKL levels and clinical attachment loss, plaque index score and bleeding on probing were observed (rho = 0.33; rho = 0.35; rho = 0.33; p < 0.05, respectively). Additionally, PICF-IL-23 and APRIL were correlated with the plaque index score and peri-implant probing depth (rho = 0.28; rho = 0.28, p < 0.05). PICF-APRIL concentrations and plaque index score were associated with PI (OR:3.01; 95%CI [1.08-8.38], p = 0.035, and OR:11.24; 95% CI [2.63-48.16], p = 0.001, respectively). The regression model, which included PICF-APRIL and plaque index, showed an AUC-ROC of 0.95, a sensitivity of 94.4%, 83.3% specificity, a positive PV of 73.9%, and a negative PV of 96.8%.
conclusionsImplants with PI have higher levels of APRIL and RANKL in PICF compared to healthy implants. The model that includes the levels of APRIL in PICF combined with the plaque index score leads to an enhanced accuracy of PI diagnosis. CLINICAL RELEVANCE: Clinical diagnosis of peri-implant disease can be improved with molecular tools, in this case, APRIL demonstrated high accuracy for the diagnosis of PI.
