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
objectiveTo investigate the value of a two-step approach with cytokeratin-18 (CK-18) and controlled attenuation parameter (CAP) in the noninvasive diagnosis of nonalcoholic steatohepatitis (NASH).
methodsA total of 65 patients with biopsy-proven nonalcoholic fatty liver disease were enrolled, including 30 patients with NASH. The M30 and M65 enzyme-linked immunosorbent assay kits were used to measure serum CK-18, and FibroScan was used to measure CAP. The receiver operating characteristic (ROC) curve was plotted, and the area under the ROC curve (AUROC) was used to determine the value of noninvasive diagnosis. The binary logistic regression model was used to calculate the predicted probability of combined diagnosis. The maximum Youden index, a sensitivity of >90%, and a specificity of > 90% were used to determine the optimal cut-off value, the low value, and the high value, respectively.
resultsThe results of the multivariate analysis showed that M65 (OR = 1.004, 95% CI 1.002-1.007, P = 0.003) and CAP (OR = 1.017, 95% CI 1.001-1.033, P = 0.036) were independent predictors of NASH. The AUROC of M65+CAP was 0.851 (95% CI 0.761-0.942), higher than 0.808 (95% CI 0.702-0.913) of M65 and 0.677 (95% CI 0.545-0.808) of CAP alone. A two-step approach with high (820.8 U/L) and low (527.7 U/L) values for M65 and the optimal cut-off value (293.5 dB/m) for CAP was used for the differential diagnosis of NASH, with a positive predictive value of 85.7%, a negative predictive value of 100%, and a coincidence rate of 92.0%.
conclusionA two-step approach with M65 and CAP can improve the value of noninvasive diagnosis of NASH, and a high negative predictive value can avoid unnecessary liver biopsy.
