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
To explore the predictive value of MRI-based radiomics model for the prognosis of liver iron burden within 2 years after hematopoietic stem cell transplantation (HSCT) in thalassemia (TM) patients who had undergone HSCT the preoperative liver 3.0T/1.5T MRI images and clinical data of 360 TM patients in two medical centers (A and B) were retrospectively analyzed. AUC, accuracy, sensitivity and specificity were used to evaluate the predictive efficacy of the model. The best performance prediction model of 3.0T/1.5T radiomics in medical center A was T1_F: the AUC, accuracy, sensitivity and specificity of the training set were 0.942/0.917, 0.91/0.8, 0.941/1 and 0.9/0.772, respectively. The AUC, accuracy, sensitivity and specificity of the test set were 0.845/0.896, 0.767/0.714, 1/1 and 0.696/0.667, respectively. The optimal performance prediction models of 3.0T/1.5T radiomics in medical center B were T1_W and T1_opp, respectively. The AUC, accuracy, sensitivity and specificity of the training set were 0.855/0.94, 0.79/0.933, 0.779/0.9 and 0.8/0.938, respectively. The AUC, accuracy, sensitivity and specificity of the test set were 0.81/0.743, 0.778/0.727, 0.73/0.727 and 0.73/0.714, respectively. It is expected that different MRI prediction models with different parameters can be constructed in different medical centers to evaluate the prognosis of liver iron burden in TM patients after HSCT.
