中位数

Median time from symptom onset to hospital admission was 4 days (interquartile range , 2 – 7 days) and from hospitalization to ICU admission was 1 day (IQR, 0 – 2 days).

从发生症状到住院的天数中位数为4天(四分位差为2– 7天)，从住院到转入ICU的天数中位数为1天(IQR为0– 2 天)。

Three new median filters are proposed in this paper, such as the weighted median filter and center weighted median filter and switching median filter.

本文在传统中位数滤波的基础上，与几种改进的中位数滤波进行比较，找出各自滤波的优劣。

The median NIH-SS score and infarct volume for acute stroke patients were 6 (interquartile range : 2 to 13) and 3.4 cc (IQR: 1.1 to 16.6), respectively.

急性脑卒中患者美国国立卫生研究院卒中评分中位数和梗死体分别为6 （四分位数间距：2至13）和3.4毫升（ IQR ：1.1-16.6）。

METHODS:: Six patients with MGD dry eye (20-58 years, median 40) and six patients with dry eye associated to SS (32-60 years, median 47) were enrolled in this study.

该研究入选了6名迈博姆腺功能障碍干眼症患者（20-58岁，中位数为40岁）和6名斯耶格伦综合征相关的干眼症患者（32-60岁，中位数为47岁）。

RESULTS: Melatonin significantly reduced the anxiety scores from 5, 3.5-6 to 3, 2-3 after premedication and to 3, 2-3.5 during surgery (P = 0.04 and P = 0.005 compared with the placebo group, respectively).

结果：褪黑素显著降低焦虑评分。给药前中位数及四分位数间距为5， 3.5-6。给药后中位数及四分位数间距为3， 2-3，术中为3， 2-3.5(P=0.04并且和分别和对照组相比 P=0.005)。

In chapterⅡ, considering GLMMs data which the number of high units is different and the number of low units is small and unbalanced, we Conduct a series of simulations, the simulations show that regardless of the number of the level 2 units,the Bayesian estimate of random effects residual variance is more precise than PQL and the PQL estimation deviates from the true value seriously; In terms of the fixed effects estimates, When the number of level 2 units is 20, The mean and median of the Bayesian estimate is more precise than PQL,But With the number of level 2 units increase,the estimate of two methods is similar. Thus, in practical applications, we recommend the use of Bayesian method.

第二章针对不同高水平单位数，低水平数较小且不平衡的GLMMs数据，进行模拟研究，研究表明：无论水平2单位数的大小，贝叶斯方法随机效应残差方差估计值远比PQL法更接近真实值，PQL法严重偏离了真实值；而对固定效应参数估计值，当水平2单位数为20时，贝叶斯法各参数的均数和中位数均要较PQL法更接近真实值，而随着水平2单位数的增加，两种方法在估计固定效应参数时相差并不大，因而，在实际应用中，推荐采用贝叶斯法。

We analyzed the regular pattern of daily medicine cost change of operation inpatients during hospitalization in every group . the results indicated that the median line of daily medicine cost had similar regular pattern in operations on the nervous system , the musculoskeletal system , the nose , mouth , and pharynx system and the female genital organs system : the top of daily medicine cost median emerged on the day of operations ; the median of daily medicine cost was low in the period after operation , and the lowest in the period before operation . the median line of daily medicine cost of operations on the digestive system and the integumentary system keeped at a high level in the period of 1 - 6 days after operations

手术病人日药费随住院时间的变化规律按icd - 9 - cm类目表的15个系统大类将住院手术病人分为15组，分析了各系统手术病人住院期间日药品费用的变化规律，结果显示：神经系统、肌肉骨骼系统、鼻口咽系统和女性生殖系统手术的日药费中位数线图具有相似的变化规律：手术病人住院期间的日药费硕士学位论文中位数的峰值位于手术当日，且手术当日的日药费变异最大；术后住院日的日药费中位数明显降低；术前住院日的日药费中位数很低；消化系统和体被系统手术在手术当日及术后1 6天内的日药费中位数维持在较高的水平。

Calculates Percentile Value statistics and the median under the assumption that your data have been grouped, and the values in the data are the midpoints of the original groups.

以下是我对这段英文的理解，不知道正确不正确，还望各位老师赐教：在你的数据已经被分组并且数据中的值是原始组的组中值的条件下，计算百分位数和中位数。

From August 21, 1998, to December 14, 2001, 57 core needle biopsy specimens suggested the possibility of phyllodes tumor. Median patient age was 42 years (range, 16-77 years), and median lesion diameter was 1.1 cm (range, 0.6-3.6 cm). Of the 57 specimens, 25 had pathological findings favoring a diagnosis of fibroadenoma, 23 favored phyllodes tumor, and nine were equivocal.

从1998年8月21日至2001年12月14日，共有57个粗针切片检查样本显示出叶状瘤的可能性，这些患者年龄中位数为42岁（范围16-77 岁），病灶直径中位数为1.1 厘米（范围 0.6-3.6 厘米），在57 个样本中，25个的病理研究结果建议为纤维性瘤，23个为叶状瘤，其余的九个诊断的意义不明确。
