Preoperative color Doppler ultrasonography predicts early recurrence in AFP-positive hepatocellular carcinoma.

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
The present study aimed to evaluate the hepatic hemodynamics of patients with α-fetoprotein (AFP)-positive hepatocellular carcinoma (HCC) and early recurrence (ER), as determined by color Doppler ultrasound. Screening with color Doppler ultrasound was performed in 150 patients with AFP-positive HCC, yielding 43 cases with postoperative ER. In addition, 35 healthy controls were enrolled in the study for comparison of the blood flow parameters between the healthy control and the HCC groups. Receiver operating characteristic curve analysis was performed to evaluate the predicted effect of Doppler for the ER of HCC. The average mean flow velocity of portal vein in patients with HCC (14.686±5.873 cm/s) was significantly lower in the HCC group compared with the healthy control group (17.631±3.569 cm/s; P=0.005). Additionally, the preoperative portal vein diameter in the HCC group was significantly higher compared with that in the healthy control group (P=0.001). Regarding the effect of surgery, the portal vein diameter was significantly increased in the patients postoperatively compared with preoperatively (P=0.003), while the pulsation and resistance indexes exhibited a decreasing trend in the postoperative group (P=0.001 and P=0.003, respectively). Notably, patients with HCC and ER presented with a higher resistance index (1.163±0.342) compared with the ER-free group (1.023±0.176; P=0.004). Furthermore, a significant difference in hepatic artery pulsation index was also observed between the ER group (0.673±0.075) and the ER-free group (0.624±0.056; P=0.018), indicating that an increased hepatic artery pulsation index may significantly predict the ER of HCC. In addition, areas under the curve of 0.683 and 0.700, respectively, suggested that the hepatic artery resistance and pulsation indexes may be used to diagnose ER in HCC (P=0.009 and P=0.004, respectively). Taken together, Doppler ultrasound provides a reliable and accurate quantification of hepatic hemodynamics for detecting ER in HCC with a good diagnostic accuracy.
