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 Input:
Context: Cicatricial alopecia is a form of hair loss that causes both cosmetic and psychological concerns. Although tissue expanders are the common approach to reconstruction, no algorithm exists in the literature for this process. In this study, it was aimed to create an algorithm for the reconstruction of lateral scalp alopecias with the goal to achieve better and standardized results.', 'Lateral scalp alopecias were divided into three groups: total lateral alopecia (type I), temporal and sideburn alopecia (type II), and sideburn alopecia (type III). Tissue expanders were placed at the parieto-occipital area in type I defects, parietal area in type II defects, and the temporal region in type III defects. Tissue expanders were used to create flaps that were advanced with 60° rotation, 90° rotation, and no rotation for type I, II, and III defects, respectively.', 'Fifteen patients were treated with this algorithm. Using this simple approach, we achieved natural, standardized aesthetic results for each patient, all of whom were satisfied with the final results.\Question: Do our experiences on the reconstruction of lateral scalp burn alopecia with tissue expanders?

Ex Output:
Although the number of case were limited, the ideal and standardized cosmetic results could be obtained by this approach.


Ex Input:
Context: To assess how different imputation methods used to account for missing variance data in primary studies influence tests of heterogeneity and pooled results from a meta-analysis with continuous outcomes.', 'Point and variance estimates for changes in serum creatinine, glomerular filtration rate, systolic blood pressure, and diastolic blood pressure were variably reported among 48 primary longitudinal studies of living kidney donors (71%-78% of point estimates were reported, 8%-13% of variance data were reported). We compared the results of meta-analysis, which either were restricted to available data or used four methods to impute missing variance data. These methods used reported P-values, reported nonparametric summaries, results from other similar studies using multiple imputation, or results from estimated correlation coefficients.', 'Significant heterogeneity was present in all four outcomes regardless of the imputation methods applied. The random effects point estimates and 95% confidence intervals varied little across imputation methods, and the differences were not clinically significant.\Question: Do imputing variance estimates alter the conclusions of a meta-analysis with continuous outcomes : a case study of changes in renal function after living kidney donation?

Ex Output:
Different methods to impute the variance data in the primary studies did not alter the conclusions from this meta-analysis of continuous outcomes. Such reproducibility increases confidence in the results. However, as with most meta-analyses, there was no gold standard of truth, and results must be interpreted judiciously. The generalization of these findings to other meta-analyses, which differ in outcomes, missing data, or between-study heterogeneity, requires further consideration.


Ex Input:
Context: Diabetic patients commonly suffer from disturbances in production and clearance of plasma lipoproteins, known as diabetic dyslipidemia, resulting in an increased risk of coronary heart disease. The study aimed to examine the cause of hypobetalipoproteinemia in two patients with type 1 diabetes.', 'The Diabetes Control and Complications Trial (DCCT) is a study demonstrating that intensive blood glucose control delays the onset and progression of type 1 diabetes complications. Hypobetalipoproteinemia was present in two DCCT subjects, IDs 1427 and 1078, whose LDL-C levels were 36 and 28 mg/dL, respectively, and triglyceride levels were 20 and 28 mg/dL, respectively. We performed exome sequencing on genomic DNA from the two patients with hypobetalipoproteinemia.', 'The subjects 1427 and 1078 had heterozygous loss-of-function mutations in the gene apolipoprotein B (ApoB), and these mutations resulted in premature stop codons at amino acid 1333 (ApoB-29) and 3680 (ApoB-81), respectively. Indeed, the plasma ApoB level of subject 1427 (19 mg/dL) was the lowest and that of subject 1078 (26 mg/dL) was the second to the lowest among all the 1,441 DCCT participants. Sequencing genomic DNA of family members showed that probands 1427 and 1078 inherited the mutations from the father and the mother, respectively.\Question: Does exome sequencing identify novel ApoB loss-of-function mutations causing hypobetalipoproteinemia in type 1 diabetes?

Ex Output:

The identification of ApoB loss-of-function mutations in type 1 diabetic patients presents innovative cases to study the interaction between hypobetalipoproteinemia and insulin deficiency.
