RSG update. Boxplots
In the last update of RSG online I have change the Histograms tab for the Distributions tab where a submenu will let you see histograms and bar graphs or boxplots. In the boxplots tab you can find, indeed, boxplots! They show the SE postop by age category, each of the two custom factors and the combination of the two custom factors, which you can switch with a checkbox. With this graphics you can compare results easier.
Also on the Upload data tab, under the data table you can find two tables showing the amount of missing values for the variables that are allowed to have them and the number of unique values for the two custom factors columns. This might give you a better insight of the data you are uploading.
Two more standard graphics added to RSG online
The last update for RSG online adds the Target Induced astigmatism (TIA) vector vs Surgically Induced astigmatism (SIA) vector and the refractive astigmatism angle of error, with these two graphics you can now make eight of the nine standard graphics to report refractive surgery outcomes.
At this point there are no plans to make the nineth one (SE refraction stability), since that would need to add too many columns to the excel.
You can test the program here.
Showing over 60 000 eyes in a graphic
The last update of RSG is online, I have added heatmaps which can be useful when having a lot of data to plot. To test it I have simulated data for 100 000 eyes, over 60 000 with target 0 with a mean and standard deviation postop SE conditioned to preop SE and age and with one operator having results different to the others.
This is the SE preop vs postop plot:
That is a thick cloud of points. Let's turn the heatmap on:
We can see now the points density, being green low density and red high density, we can also see that the points fall in fixed SE postop values shown by the red lines, also that preop there are more within -6 and -1 and that there are much less around 0 SE preop, as expected. At the bottom left we see that there are 62 239 eyes represented.
The following graph shows the graphic separated by doctor:
Well, it seems that Dr. E red cloud is less intense and larger, indicating a greater variability in the outcomes (it could also be that there are much less eyes than the others, but here all have the same, that can be easily checked in the histograms tab). It is also a bit lower than the rest so the mean SE is also lower that the others.
You can test it here.
