You will be given a definition of a task first, then some input of the task.
Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

To find sensitive and specific laboratory examination items for early diagnosing and monitoring liver transplantation reject reaction.', 'Randomly investigate 41 liver transplantation patients, among them there were 16 patients with reject reaction (including 12 with acute rejection, 4 with chronic rejection). Plasma soluble thrombomodulin (STM) and von Willebrand factor (vWF) levels were measured before operation and every other day after operation.', 'Plasma STM level increased significantly after operation, two days before rejection and after acute rejection (5.58 ng/ml +/- 0.42 ng/ml, 5.93 ng/ml +/- 0.45 ng/ml, and 7.88 ng/ml +/- 0.29 ng/ml, respectively), so did vWF level (101.2% +/- 4.68%, 104.3% +/- 5.78%, and 127.7% +/- 5.74%, respectively). STM level was much higher in acute rejection than that in chronic rejection (7.88 ng/ml +/- 0.29 ng/ml vs. 6.35 ng/ml +/- 0.54 ng/ml, t = 2.46, P < 0.05), in no reaction group after impacting therapy than in effective group (8.30 ng/ml +/- 0.19 ng/ml vs. 3.82 ng/ml +/- 0.22 ng/ml, t = 12.98, P < 0.01), and in dead group after treatment than in living group (7.98 ng/ml +/- 0.18 ng/ml vs. 6.51 ng/ml +/- 0.41 ng/ml, t = 3.39, P < 0.01).
Output:
Do [ Values of soluble thrombomodulin and von Willebrand factor judging reject reaction in liver transplantation ]?
