In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[EX Q]: Context: Familial hypercholesterolemia (FH) is a genetic disorder characterized by elevated levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). Guidelines recommend cholesterol-lowering medication from 8 to 10 years of age and dietary recommendations. Little is known about the diet of FH children and the effect of dietary counseling. The aim of the study was to describe the diet of FH children with respect to fat quality, and to investigate if dietary counseling improved lipid profile.', 'Fifty-four FH children (5-18 years) were included in the study and dietary intake was recorded with a pre-coded food diary for four days. Information about plasma lipid levels was obtained.', 'Median intake of total fat, monounsaturated fat, polyunsaturated fat (PUFA) and saturated fat (SFA) was 30.8, 10.4, 5.9 and 12.0\xa0E %, respectively. Among non-statin treated FH children, SFA intake was significantly correlated with TC, LDL-C and apolipoprotein (apo) B (rsp\xa0=\xa00.55; p\xa0=\xa00.004, rsp\xa0=\xa00.46; p\xa0=\xa00.02, and rsp\xa0=\xa00.45; p\xa0=\xa00.02, respectively), and PUFA/SFA ratio significantly inversely correlated with TC (rsp\xa0=\xa0-0.42; p\xa0=\xa00.03). Compared to the first visit, non-statin and non-plant sterol treated FH children (n\xa0=\xa010) had significantly reduced levels of TC (p\xa0<\xa00.01), LDL-C (p\xa0=\xa00.01), high-density lipoprotein cholesterol (p\xa0=\xa00.02), apo B (p\xa0=\xa00.05) and apo A-1 (p\xa0=\xa00.02) levels at a later visit.\Question: Is dietary counseling associated with an improved lipid profile in children with familial hypercholesterolemia?
[EX A]: FH children had a higher intake of SFA than recommended and the SFA intake was positively correlated with plasma TC, LDL-C and apo B levels in FH children not using statins. Importantly, the plasma lipid profile was improved in FH children after dietary counseling where focus was on reducing intake of SFA and dietary cholesterol.

[EX Q]: Context: Cytokeratin 19 is significant for indicating cancer cells, and Cyfra 21-1 is a fragment of cytokeratin 19. This retrospective study was designed to define the prognostic value of serum Cyfra 21-1 in epithelial ovarian cancers (EOC).', 'Serum Cyfra 21-1 concentration was obtained from 42 patients with EOC prior to treatment. Various prognostic aspects were examined using univariable and multivariable analyses. The standard serum marker cancer antigen 125 was measured simultaneously and compared in this analysis.', 'Serum levels of both Cyfra 21-1 and cancer antigen 125 were associated with positive retroperitoneal lymph nodes and platinum resistance; higher levels of Cyfra 21-1 (3.0\xa0ng/mL as the cut-off) were associated with shorter disease-free survival (16 months vs. 28 months, p\xa0=\xa00.001) and overall survival (29 months vs. 41 months, p\xa0=\xa00.007) than lower levels. Further univariable analysis showed that Cyfra 21-1, poor differentiation, and retroperitoneal lymph node metastasis were related to platinum resistance and mortality. Multivariable analysis indicated retroperitoneal lymph node metastasis and serum Cyfra 21-1 were independent risk factors for both disease-free survival and overall survival.\Question: Is serum cytokeratin-19 fragment ( Cyfra 21-1 ) a prognostic indicator for epithelial ovarian cancer?
[EX A]: The pretreatment level of serum Cyfra 21-1 had remarkable prognostic significance for EOC, indicating poor survival when it was elevated above 3.0 ng/mL.

[EX Q]: Context: Single-laboratory experience showed that flow cytometric (FCM) assessment of minimal residual disease (MRD) in acute lymphoblastic leukemia (ALL) is feasible in most patients and gives independent prognostic information. It is, however, not known whether FCM analysis can reliably be standardized for multicentric application.', 'An extensive standardization program was installed in four collaborating laboratories, which study FCM-MRD in children treated with the AIEOP-BFM-ALL 2000 protocol. This included methodological alignment, continuous quality monitoring, as well as personnel education by exchange and performance feed-back.', 'Blinded inter-laboratory tests of list-mode data interpretation concordance (n = 202 blood and bone marrow samples from follow-up during induction of 31 randomly selected patients of a total series of n = 395) showed a very high degree of inter-rater agreement among the four centers despite differences in cytometers and software usage (intraclass correlation coefficient [ICC] 0.979 based on n= 800 single values). Lower concordance was reached with amounts of MRD below 0.1%. Comparing data from sample exchange experiments (n = 42 samples; ICC 0.98) and from independent patient cohorts from the four centers (regarding positive samples per time-point of follow-up as well as risk estimates) concordance was also good.\Question: Is standardization of flow cytometric minimal residual disease evaluation in acute lymphoblastic leukemia : Multicentric assessment feasible?
[EX A]:
MRD-evaluation by FCM in ALL can be standardized for reliable multicentric assessment in large trials.
