This study aimed to develop and validate nomograms predicting the survival of osteosarcoma patients from SEER database our hospital. Data 1,066 were randomly divided into a development cohort (n=800) validation one (n=266). Another 126 hospital was utilized as two. Univariate multivariate Cox analyses performed identify independent prognostic factors for overall (OS) cancer-specific (CSS). Nomo...

Determing the required optimal amount of laser correction formulas and nomograms were derived to using clinical functional results obtained in 233 patients with mild moderate hyperopia (233 eyes) before after FemtoLASIK.

Two nomograms are given for use in calculating standard, C3, or maximum, Cm, urea clearance. The first nomogram calculates the urine flow rate, f, from the urine collection time and volume data. With the second nomogram, values of f and urea nitrogen concentrations in blood serum (or plasma) and urine are used to calculate either C3 or Cm, according to the value of f. There is no intermediate c...

Cancer prediction nomograms provide advanced practitioners (APs) with tools to assess a patient’s overall risk for development of a specific cancer. Alternatively, after a cancer diagnosis has been made, nomograms represent a standardized means to provide a statistical estimate of prognosis, particularly in individuals with characteristics of high-risk disease. According to the National Cancer ...

If you are a vet, you will often need to know the weight of an animal, for example to prescribe the right amount of a drug. If your animal is a rabbit, this is not a problem. But if your animal is large, say a donkey, and if you are out in the field, then you will not be able to weigh the animal directly. However, if you have a tape measure then you can weigh the animal indirectly, if you have ...
