Construction and verification of nomogram prediction model for non-suicidal self-injury in adolescents with depression.

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
backgroundAccurate identification of high-risk individuals for NSSI and timely intervention are critical for mitigating self-harm risk. This study aimed to develop a predictive model for NSSI behaviors in adolescents with depression.
methodsA convenience sample of 596 adolescents with depression was assessed, with 455 assigned to the training and internal validation set and 144 to the external validation set. Nine key predictors were identified through univariate analysis, LASSO regression, and binary logistic regression, including birth mode, history of peer self-harm, parental psychiatric disorders, sleep duration, social life events, self-esteem, psychological resilience, social support, and depression severity. A nomogram-based prediction model was constructed from these factors, with model performance evaluated via ROC curves, AUC values, Hosmer-Lemeshow test, and calibration curves. Clinical applicability was determined using decision curve analysis (DCA).
resultsThe model exhibited an AUC of 0.880 (P < 0.001), with sensitivity of 0.933 and specificity of 0.765. The Hosmer-Lemeshow test confirmed good model fit (χ
conclusionThe nomogram-based risk model developed in this study effectively predicts NSSI behaviors in adolescents with depression, offering significant scientific and clinical value and warranting further implementation.
