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: To systematically review methodological articles which focus on nonpublication of studies and to describe methods of detecting and/or quantifying and/or adjusting for dissemination in meta-analyses. To evaluate whether the methods have been applied to an empirical data set for which one can be reasonably confident that all studies conducted have been included.', 'We systematically searched Medline, the Cochrane Library, and Web of Science, for methodological articles that describe at least one method of detecting and/or quantifying and/or adjusting for dissemination bias in meta-analyses.', 'The literature search retrieved 2,224 records, of which we finally included 150 full-text articles. A great variety of methods to detect, quantify, or adjust for dissemination bias were described. Methods included graphical methods mainly based on funnel plot approaches, statistical methods, such as regression tests, selection models, sensitivity analyses, and a great number of more recent statistical approaches. Only few methods have been validated in empirical evaluations using unpublished studies obtained from regulators (Food and Drug Administration, European Medicines Agency).\Question: Are methods for detecting , quantifying , and adjusting for dissemination bias in meta-analysis described?

Output: We present an overview of existing methods to detect, quantify, or adjust for dissemination bias. It remains difficult to advise which method should be used as they are all limited and their validity has rarely been assessed. Therefore, a thorough literature search remains crucial in systematic reviews, and further steps to increase the availability of all research results need to be taken.


Input: Consider Input: Context: This study investigated whether anxiety, fear of pain, or pain catastrophizing were predictive of pain-related outcomes after induced delayed onset muscle soreness (DOMS) at the shoulder.', 'Healthy participants (19 males and 23 females) were eligible for participation if they had (a) no history of neck or shoulder pain, (b) no sensory or motor impairments of the upper-extremity, (c) not regularly participating in upper-extremity weight training, (d) not currently or regularly taking pain medication, and (e) no history of upper-extremity surgery. Participants completed self-report measures for fear of pain, pain catastrophizing, and anxiety. Then, participants underwent a standard fatigue protocol to induce DOMS in the shoulder external rotator muscles. Participants were reassessed 24 hours after DOMS induction on clinical and evoked pressure pain reports, muscle force production, self-report of upper-extremity disability, and kinesiophobia. Stepwise regression models considered sex, anxiety, pain intensity, fear of pain, and pain catastrophizing as outcome predictors.', 'Fear of pain alone explained 16% (P=0.008) of the variance in clinical pain and 10% (P=0.047) evoked pressure pain intensity. Clinical pain intensity alone explained 11% (P<0.031) of the variance in muscle force production. Clinical pain intensity and fear of pain explained 50% (P<0.001) of the variance in upper-extremity disability, whereas fear of pain and sex accounted for 26% (P=0.005) of the variance in kinesiophobia.\Question: Does fear of pain influence outcomes after exercise-induced delayed onset muscle soreness at the shoulder?

Output: With the exception of muscle force production, fear of pain had a consistent influence on shoulder DOMS outcomes, even after controlling for pain intensity. This study suggests fear of pain may be a relevant psychologic factor to consider in clinical studies investigating the development and treatment of chronic shoulder pain.


Input: Consider Input: Context: Renal ultrasound is very important in the diagnosis of renal tumors.', 'From January 2000 to Jannuary 2005 we retrospectively examined the records of 116 patients, 37 women and 79 men (mean age 54 years, range 22-77), who underwent radical nephrectomy for kidney cancer in clinical stage CT1N0M0. 2.5 cm was the tumor dimension limit between the nephron sparing surgical technique and radical nephrectomy. We subdivided the sample into 2 groups, the first of 45 patients with tumor lesions smaller than 2.5 cm and the second with tumor lesions between 2.5 cm and 7 cm in diameter all patients underwent preoperative staging including ultrasound scan (ETG) and computer tomography scan (CT).', 'Ultrasound has showed 35% sensitivity and 49% specificity for lesions under 2.5 cm in diameter, and 65% sensitivity and 75% specificity and 80% specificity for lesions under 2.5 and 80% sensitivity and 95% specificity for lesions between 2.5 and 7 cm.\Question: Do detection rate of ultrasound vs CT scan in clinical staging accuracy of renal tumors pT1NxMx?


Output: Ultrasound is the first step in the staging of renal cancer before surgery; to assess. 2.5 and 7 in diameter CT scan is the gold standard for solid and cystic lesions.
