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
Background: Peripheral nodular cholangiocarcinoma (PCC) and hepatic hemangioma (HG) significantly differ in treatment strategies and prognosis. However, they can present similar imaging characteristics, making them difficult to distinguish. The distinction between PCC and atypical HG using pre-operative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) holds substantial significance. Methods: Fifty-four cases of solitary hypovascular hepatic nodules (nodules ≤3 cm in diameter and enhancement not exceeding the hepatic parenchyma) confirmed pathologically were collected, including 25 cases of PCC and 29 cases of HG. The clinical and DCE-MRI features were observed, and the apparent diffusion coefficient (ADC) values were compared. The Results: The signal of PCC was more heterogeneous and could be shown as a ring hyperintensity signal on diffusion weighted imaging (DWI). The T2-weighted imaging (T2WI) signal of HG lesions showed a more homogeneous high-intense signal. The ADC value of PCC patients was lower than that of HG patients. Most of the patients in the two groups presented marginal enhancement in the arterial phase with infrequent abnormal perfusion around. The intratumoral vascular traversal signs in the PCC group showed a diagnostic significance. Among the lesions with marginal enhancement at arterial stage, the enhancement in PCC group was more likely to have annular enhancement with the main manifestation of delay reduction and nebulous or separated/astral center. On the other hand, HG tended to be more likely to have nodular enhancement in the arterial phase with delayed invariance at the margins and with no significant enhancement at the center. The area under the curves (AUC) of the three radiologists before and after the two readings were 0.645 and 0.888, respectively. Conclusions: In the differentiation of PCC and atypical liver hemangioma, the presence of a circular hyper-intense signal in DWI, the ADC values, and the pattern and extent of enhancement of marginal and central lesions were of diagnostic significance.
