The art of nomograms
Background To retrospectively analyse strategies for adjusting refractive surgery plans with reference to the preoperative manifest refraction. Methods We constructed seven nomograms based on the refractive outcomes (sphere, cylinder, axis [SCA]) of 150 consecutive eyes treated with laser in situ keratomileusis for myopic astigmatism. We limited the initial data to the SCA of the manifest ref...
متن کاملOf Donkeys and Nomograms
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 ...
متن کاملConstructing Interactive Nomograms
Nomograms graphically encode mathematical relationships between multiple parameters. Historically, nomograms enjoyed wide use as analog computation devices, but understandably fell out of favor with the advent of more powerful calculators, computers, and related software. Yet, certain examples of nomograms encode complex relationships that are not easily visualized using more common forms such ...
متن کاملNomograms need to be presented in full.
We read with great interest the recent article by Pan et al describing the development of a nomogram to predict the 5-year and 8-year survival probability for patients with nondisseminated nasopharyngeal cancer. However, there are some aspects surrounding the evaluation of the model and reporting of the study that are of concern. When evaluating the performance of a clinical prediction model, i...
متن کاملNomograms of Iranian fetal middle cerebral artery Doppler waveforms and uniformity of their pattern with other populations' nomograms
BACKGROUND Doppler flow velocity waveform analysis of fetal vessels is one of the main methods for evaluating fetus health before labor. Doppler waves of middle cerebral artery (MCA) can predict most of the at risk fetuses in high risk pregnancies. In this study, we tried to obtain normal values and their nomograms during pregnancy for Doppler flow velocity indices of MCA in 20-40 weeks of norm...
