Clinical Outcome and Predictors of Customized Polyetheretherketone Post-and-Cores for Residual Root and Crown: A Retrospective Study.

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
objectivesThis retrospective, non-interventional study aimed to evaluate the longevity and factors influencing the success of custom-fabricated polyetheretherketone (PEEK) post-and-cores in endodontically treated teeth (ETT). MATERIAL AND
methodsDuring the observation period (2019-2022), 63 patients received 100 customized PEEK post-and-cores. Clinical outcomes were analyzed based on the following parameters: age, gender, tooth type, tooth position, proximal contacts, remaining cavity walls, antagonist contacts, and final restoration. Kaplan-Meier analysis was used for the survival probability. Log-rank tests were used to identify univariate associations between failure rates and other potential factors. Cox regression was used to assess the risk of failure and determine possible risks between the identified factors at a cut-off point p-value (0.25 in univariate analysis).
resultsThe median follow-up duration was 20.62 months, with a maximum of 40.57 months. 93 restorations were judged as successful and 99 teeth survived. The main failure type was decementation of the restoration (n = 4). The annual failure rate was 3.4%. Gender, remaining tooth structure, and final restoration were found to be correlated with success rates in the preliminary univariate analysis (Log-rank tests) to determine the association between failure rates and potential factors. Multifactorial survival analysis (Cox regression) showed that teeth with coronal walls had a significantly lower failure risk than deprived teeth, even with the ferrule effect. (HR = 0.04; 95% CI for HR = 0.01-0.29; p = 0.002).
conclusionsPEEK post-and-cores adapt well to clinical restorative needs and offer favorable short-term clinical outcomes. The remaining cavity wall was a significant success rate predictor.
