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.

Input: Consider Input: Context: In Crohn's disease (CD), rapid response to anti-tumor necrosis factor therapy improves short- and medium-term outcomes, but the relationship between early remission (ER) and long-term remission is unclear.", 'This exploratory analysis of PRECiSE 3 (NCT00160524) assessed whether ER after initiation of certolizumab pegol predicted long-term remission.', 'Patients enrolled in PRECiSE 3 had completed PRECiSE 1 or 2, two randomized placebo-controlled studies for moderate to severe CD, and received open-label certolizumab pegol 400\u2009mg every 4 weeks for a total treatment duration of ≤7.5 years. Time to loss of remission between patients with and without ER (Harvey-Bradshaw Index ≤4 at or before Week 6 of PRECiSE 1 or 2) was compared by log-rank test of Kaplan-Meier estimates.', 'At baseline, patients with (n\u2009=\u2009242) and without (n\u2009=\u2009148) ER had mean (standard deviation [SD]) durations of CD of 6.8 (6.6) and 7.4 (7.8) years, mean (SD) CD Activity Index scores of 280.3 (53.4) and 311.1 (55.5), with 45.5% and 41.9% of patients having ileocolonic CD, and median C-reactive protein concentrations of 8.0 and 5.0\u2009mg/L, respectively. Median certolizumab pegol plasma concentrations during the first 6 weeks of therapy were similar in both groups. Mean time to loss of remission was significantly longer in patients with versus without ER (2.77 vs. 1.14 years, p\u2009<\u20090.0001).\Question: Does early remission status predict long-term outcomes in patients with Crohn 's disease treated with certolizumab pegol?

Output: In certolizumab pegol-treated patients with CD, ER appears to be an important predictor of long-term clinical remission. Prospective trials are needed to determine whether ER improves other long-term outcomes.


Input: Consider Input: Context: B-type natriuretic peptide (BNP) correlates with cardiac filling pressures and outcomes in patients with heart failure. In heart transplant recipients, we hypothesize that a within-individual change in BNP over time would be more helpful than absolute BNP in detecting International Society of Heart and Lung Transplantation (ISHLT) grade 2R or greater rejection.', 'N-terminal pro-BNP (NT-proBNP) levels were measured in 146 consecutive transplant recipients undergoing routine endomyocardial biopsies. In the cross-sectional analysis, multiple observations per individual were accounted for using generalized estimation equations.', "A cross-sectional analysis demonstrated a weak association between NT-proBNP levels and rejection, with an odds ratio (OR) of 1.01 for every 100-pg/mL increase in NT-proBNP (p = 0.02). However, with a doubling of an individual's NT-proBNP level, the OR for significant rejection was 2.9 (95% confidence interval [CI] 1.2-7.0), the OR with a 5-fold increase was 9.1 (95% CI, 2.7-31.5), and the OR with a 10-fold increase was 27.7 (95% CI, 5.9-129). A 10-fold increase in NT-proBNP offered a negative predictive value of 95% for the diagnosis of rejection. The relationship between within-individual increases in NT-proBNP and rejection persisted after adjusting for a fall in ejection fraction and a rise pulmonary capillary wedge pressure, and was a stronger predictor than changes in these parameters.\Question: Does the change in B-type natriuretic peptide levels over time predict significant rejection in cardiac transplant recipients?

Output: There is a strong, graded relationship between the within-individual increase in NT-proBNP and the odds of significant rejection independent of hemodynamic parameters. These results suggest that the change in NT-proBNP rather than absolute BNP levels may offer a non-invasive approach to detect rejection.


Input: Consider Input: Context: Considerable variation in seed size commonly exists within plants, and is believed to be favoured under natural selection. This study aims to examine the extent to which seed size distribution depends on the presence of competing neighbour plants.', 'Phaseolus vulgaris plants rooting with or without a conspecific neighbour were grown in soil with high or low nutrient availability. Seeds were harvested at the end of the growth cycle, the total nitrogen and phosphorus invested in seed production were measured and within-plant seed size distribution was quantified using a set of statistical descriptors.', "Exposure to neighbours' roots induced significant changes in seed size distribution. Plants produced proportionally more large seeds and fewer small ones, as reflected by significant increases in minimal seed size, mean seed size, skewness and Lorenz asymmetry coefficient. These effects were different from, and in several cases opposite to, the responses when the soil nutrient level was reduced, and were significant after correction for the amount of resources invested in seed production.\Question: Does the presence of a below-ground neighbour alter within-plant seed size distribution in Phaseolus vulgaris?


Output: Below-ground neighbour presence affects within-plant seed size distribution in P. vulgaris. This effect appears to be non-resource-mediated, i.e. to be independent of neighbour-induced effects on resource availability. It implies that, based on current environmental cues, plants can make an anticipatory adjustment of their investment strategy in offspring as an adaptation to the local environment in the future.
