The performance of the nomogram was evaluated through internal and external validations. Bootstrapping was used to perform 1000 instances of resampling to internally validate the predictive performance of the nomogram to ensure the stability and reliability of the model’s performance. The discrimination of the nomogram was assessed using the Concordance index (C-index) and receiver operating characteristic (ROC) curve.

In this study, we aimed to develop a nomogram for predicting outcomes in older adults presenting with clinical symptoms suggestive of CAD. We hypothesized that a combination of baseline SIRT6 levels with clinical parameters could improve the evidence-based selection of candidates for this marker and facilitate clinical decision-making, resulting in its potential implementation in clinical trials.

LR models and nomograms were developed using R (version 4.1.1; R Core Team) with the “glmnet” and “rms” packages for model fitting and nomogram visualization [19]. Python’s “scikit-learn” library (version 0.24.2) was used for supplementary ML and validation tasks [20]. In addition, SPSS Statistics (version 25; IBM Corp) was used for statistical testing [21].

This study identified risk factors and developed a screening tool with a nomogram to prevent the transition from MHO to MUO. A nomogram, a graphical tool that can perform a complicated approximation calculation, provided a clear interpretation of which predictors could be more critical factors [13]. The use of this scale also allows the general population to intuitively and easily assess the likelihood of transitioning to MUO.

Additionally, to enhance practical usability for health care professionals globally and enable open validation by peers, we have implemented the 2 nomogram tools online using Dyn Nom [23,24]. Through this platform, the SBI risk score can be automatically generated and visually displayed.
In this study, a total of 945 patients clinically diagnosed with infective fever and possessing complete clinical data were included. Table 1 presents the demographic characteristics of these patients.

One example is the Dyn Nom package [7] in R that predisplays the results of statistical models as a dynamic nomogram and readily allows individual prediction with 95% CI.
Anesthetic guidelines and protocols increasingly drive standardization of practice [10]. However, we believe that individual identification of risk is more likely to improve outcomes [11].

In addition, if logistic regression performs well compared with the other three methods, we will formulate a nomogram based on the result of logistic regression for practical use. The nomogram works by proportionally converting each regression coefficient into a 0 to 100-point scale, with 100 points being the highest β coefficient. The points across each independent variable are added to derive total points, which are translated to predicted probabilities [28].

Nomogram, calibration, and receiver operating characteristic (ROC) curves were established using R version 3.6.1 (R Project). The risk score was calculated using multivariate Cox regression. The cutoff values of independent risk factors were based on the maximum Youden index. A 2-sided α
All 175 patients in this study were confirmed to be infected with SARS-Co V-2. The average age of the 175 patients was 46.9 years (SD 17.33).

We constructed the nomogram (Figure 3) using the development database based on an independent prognostic marker (age) and a rank variable (Killip classification). To use the nomogram, the patient’s age is found on the AGE axis, and a straight line is then drawn upward to the Points axis to determine how many points toward progression the patient receives for their age. The steps are repeated for the other axes, with a straight line drawn upward each time toward the points axis.
