I am using the following code
https://github.com/MIT-LCP/mimic-code/blob/main/mimic-iii/concepts/severityscores/lods.sql
to calculate lods score.
Is this the right one to use?
I noticed in the code,
for renal score it has - " when bun_max >= 7.50 then 1" which seems not right as the one above "bun_max >= 17.0 then 1" is the right one (i.e 17.0 to 28.0 is I think considered score of 1).

Also i noticed in a related query,
https://github.com/MIT-LCP/mimic-code/pull/112,
the code is bit different (and units are also different) but seems right(when (BUN_Max >= 6 and BUN_Max <10) then 1).:

Could someone clear my doubt about, whether am i using the right code and whether the additional line in the first code affects the calculation for renal score?

Thanks,
Selva

Read mimic-iii/concepts/severityscores/lods.sql and compare its BUN branches with pull request #112, paying attention to the units stated in each query. Confirm whether the extra bun_max threshold is intentional and whether it changes the renal score, then document the finding or proposed correction.
