In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Random and Systematic Errors

14.7K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Directing Effect of Substituents: meta-Directing Groups

5.9K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Systematic Sampling Method01:17

Systematic Sampling Method

12.7K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Propagation of Uncertainty from Systematic Error

1.4K
The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Summary
This summary is machine-generated.

This systematic review found that experimental unconventional perfusion flaps have a high overall survival rate of 90.8%. Rabbit, rat, and canine models effectively mimic clinical applications in human medicine.

Area of Science:

  • Surgical Innovation
  • Experimental Medicine
  • Flap Reconstruction

Background:

  • Unconventional perfusion flaps offer advantages over traditional methods.
  • Existing literature is fragmented across species and techniques.
  • A comprehensive synthesis of experimental data is needed.

Purpose of the Study:

  • To systematically review and meta-analyze experimental unconventional perfusion flaps.
  • To identify optimal experimental models.
  • To estimate the global survival rate of these flaps.

Main Methods:

  • Systematic review and meta-analysis of English, French, Italian, Spanish, and Portuguese articles.
  • Literature search of PubMed from 1981 to February 1, 2017.
  • Analysis of 68 studies, 86 models, and 1073 flaps.

Main Results:

  • Overall survival rate for unconventional perfusion flaps was 90.8%.
  • 74.4% of flaps showed complete or near-complete survival.
  • Rabbit, rat, and dog were common species; survival rates did not differ significantly by species or vascular pattern.

Conclusions:

  • Experimental models using rabbits, rats, and dogs show high flap survival.
  • These animal models may accurately reflect clinical outcomes in human medicine.
  • Further research can leverage these validated experimental models.
