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.

Example Input: Context: Evidence suggests that advance directives may improve end-of-life care among seriously ill patients, but improving completion rates remains a challenge.', 'This study tested the influence of increasing the number of options for completing an advance directive among seriously ill patients.', 'Outpatients (N = 316) receiving hemodialysis across 15 dialysis centers in the Philadelphia region between July 2014 and July 2015 were randomized to receive either the option to complete a brief advance directive form or expanded options including a brief, expanded, or comprehensive form. Patients in both groups could decline to complete an advance directive or take their selected version home. The primary outcome was a returned, completed advance directive. Secondary outcomes included whether patients wanted to complete an advance directive, decision satisfaction, quality of life at 3 months, and patient factors associated with advance directive completion.', 'Although offering more advance directive options was not significantly associated with increased rates of completion (13.1% in the standard group v. 12.2% in the expanded group, P = 0.80), it did significantly increase the proportion of patients who wanted to complete an advance directive and took one home (71.9% in standard v. 85.3% in expanded, P = 0.004). There was no difference in satisfaction (P = 0.65) or change in quality of life between groups (P = 0.63). A higher baseline quality of life was independently associated with advance directive completion (P = 0.006).\Question: Does a Randomized Trial of Expanding Choice set to Motivate Advance Directive Completion?
Example Output: These results suggest that although an expanded choice set may initially nudge patients toward completing advance directives without restricting choice, increasing actual completion requires additional interventions that overcome downstream barriers.

Example Input: Context: To describe the findings of enhanced depth imaging (EDI) optical coherence tomography (OCT) of the lamina cribrosa (LC) in glaucoma and pachychoroid spectrum diseases associated with peripapillary retinoschisis.', 'Retrospective, observational case series.', 'A total of 16 patients from 1 institution.', 'Detailed medical case histories, optic disc and retinal imaging with EDI using the Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany), and clinical course were reviewed for patients with peripapillary retinoschisis without a known predisposing condition.', 'Clinical features and findings of the EDI OCT.', 'Among the 16 eyes with peripapillary retinoschisis that had abnormal findings on EDI of the LC, 8 had glaucoma and 8 had pachychoroid spectrum diseases, including chronic central serous chorioretinopathy (CSC) (6 eyes), small pigment epithelium detachment (1 eye), and polypoidal choroidal vasculopathy (PCV) (1 eye). The abnormal LC findings were central or peripheral focal LC defects in eyes with glaucoma and LC disinsertions or peripheral focal LC defects in eyes with pachychoroid spectrum diseases. Central LC defects were related to inner layer retinoschisis, whereas LC disinsertions and peripheral LC defects were related to outer layer retinoschisis. The peripapillary retinoschisis did not show a topographic association with the underlying chronic CSC- or PCV-associated lesions. In 6 treated eyes with pachychoroid, peripapillary retinoschisis resolved along with subretinal fluid after anti-vascular endothelial growth factor injection in 4 eyes, whereas retinoschisis persisted after the resolution of subretinal fluid in 2 eyes.\Question: Do alterations of the Lamina Cribrosa Are Associated with Peripapillary Retinoschisis in Glaucoma and Pachychoroid Spectrum Disease?
Example Output: Enhanced depth imaging OCT of the LC demonstrated alterations associated with peripapillary retinoschisis, pachychoroid spectrum diseases, and glaucoma.

Example Input: Context: The counterbalance of macrophage migration inhibitory factor (MIF) and Gremlin-1 is a useful tool to predict the acuity of coronary artery disease (CAD) and plaque stability. Gremlin1 is an endogenous antagonist of MIF and therefore influences plaque vulnerability. This study was designed to elucidate the mechanistic basis determining the biophysical binding of Gremlin-1 to MIF.', 'An in silico model suggested that several charged C-terminal amino acids are crucial in mediating Gremlin-1/MIF-binding. We produced several single amino acid exchange mutants of Gremlin-1 by site-directed mutagenesis. These Gremlin-1 mutants were tested for their ability to reduce MIF effects on monocytes.', 'We observed that the critical element of the Gremlin-1 molecule for regulating MIF-induced chemotactic activity lies at the C-terminal region. A single amino acid exchange of an arginine to an alanine residue is sufficient to abolish the antagonistic effect of Gremlin-1 on MIF. Therefore, the Gremlin-1 mutant R172A failed to reduce MIF-induced monocyte differentiation into macrophages.\Question: Does gremlin-1 C-Terminus regulate Function of Macrophage Migration Inhibitory Factor ( MIF )?
Example Output:
Gremlin-1 C-terminus is essential for antagonizing MIF effects. Our results could offer a novel strategy utilizing Gremlin-1 to target pro-inflammatory effects of MIF in various diseases.
