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.

Ex Input:
The apolipoprotein B (apoB)/apoA-I ratio represents the balance of proatherogenic and antiatherogenic lipoproteins. The purpose of this study was to determine whether the apoB/apoA-I ratio was superior to any of the cholesterol ratios - total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C), low-density lipoprotein cholesterol (LDL-C)/HDL-C and non-HDL-C/HDL-C - in predicting the risk of coronary disease. Moreover, we examined whether any lipids, lipoproteins or cholesterol ratios add significant predictive information beyond that provided by the apoB/apoA-I ratio.', 'Plasma lipids, lipoproteins, apoB, and apoA-I were measured in 69,030 men and 57,168 women above 40 years of age. After a mean follow-up of 98 months, 1183 men and 560 women had died from a myocardial infarction in this prospective apolipoprotein-related mortality risk (AMORIS) study.', 'High apoB and a high apoB/apoA-I ratio were strongly related to increased coronary risk, while high apoA-I was inversely related to risk. The apoB/apoA-I ratio was superior to any of the cholesterol ratios in predicting risk. This advantage was most pronounced in subjects with LDL-C levels <3.6 mmol/l. Addition of lipids, lipoproteins or any cholesterol ratio to apoB/apoA-I in risk models did not further improve the strong predictive value of apoB/apoA-I.

Ex Output:
Is the apoB/apoA-I ratio better than the cholesterol ratios to estimate the balance between plasma proatherogenic and antiatherogenic lipoproteins and to predict coronary risk?


Ex Input:
Transcranial direct current stimulation (tDCS) of the primary motor cortex has been shown to modulate pain and trigeminal nociceptive processing.', 'Ten patients with classical trigeminal neuralgia (TN) were stimulated daily for 20\xa0minutes over two weeks using anodal (1\xa0mA) or sham tDCS over the primary motor cortex (M1) in a randomized double-blind cross-over design. Primary outcome variable was pain intensity on a verbal rating scale (VRS 0-10). VRS and attack frequency were assessed for one month before, during and after tDCS. The impact on trigeminal pain processing was assessed with pain-related evoked potentials (PREP) and the nociceptive blink reflex (nBR) following electrical stimulation on both sides of the forehead before and after tDCS.', 'Anodal tDCS reduced pain intensity significantly after two weeks of treatment. The attack frequency reduction was not significant. PREP showed an increased N2 latency and decreased peak-to-peak amplitude after anodal tDCS. No severe adverse events were reported.

Ex Output:
Does patient-conducted anodal transcranial direct current stimulation of the motor cortex alleviate pain in trigeminal neuralgia?


Ex Input:
To examine the relationship between statin use in Chinese patients with intracerebral hemorrhage (ICH) during their hospitalization and the outcomes.', 'Data were collected from the China National Stroke Registry. Good functional outcome was defined by a modified Rankin Scale score between 0-2. Functional outcome and rate of mortality at 3 months and 1 year were compared between ICH patients on statin and those without it during their hospitalization. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated using the multivariable logistic regression model adjusted for baseline risk factors.', 'Among 3218 consecutive ICH patients from 2007 to 2008, 220 (6.8%) were on statin during their hospitalization. Compared with those without statin, patients on statin were younger, had more stroke risk factors but lower stroke severity. ICH patients on statin had better functional outcome at 3 months (OR 2.24, 95% CI 1.49-3.36) and at 1 year (OR 2.04, 95% CI 1.37-3.06). They also had lower rate of mortality at 3 months (OR 0.44, 95% CI 0.22-0.87) and 1 year (OR 0.49, 95% CI 0.27-0.86).

Ex Output:

Does use of statin during hospitalization improve the outcome after intracerebral hemorrhage?
