yamaa As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.

Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: give each electrocardiogram (ECG) the sequence number (PCSEQ)
and concentration (PCCONC) of the subject's plasma sample nearest in time
to it.
Input: ECG records, each with its sequence number and date and time, and pharmacokinetic (PK) concentration records, each with its sequence number, date/time and result.
Variables:
PCSEQwould be the sequence number of the subject's sample nearest in time to the ECG.PCCONCwould be the concentration of that sample.
Note: the sample is to be chosen as the one nearest the ECG, yet the earlier choice of the subject's latest sample is still stated beside it. The two choices can disagree, and nothing says which one wins, so the specification is rejected before any record is read and no artifact is accepted.
How to fix
Decide which sample an ECG takes. When it is the sample nearest in time, remove the order and the choice of the last record:
intermediates:
- id: NEAREST
dataset: PC
key: [STUDYID, USUBJID]
nearest: {source: PCDTM, to: EG.EGDTC, unit: minute}
columns: [PCSEQ, PCSTRESN]
When it is the subject's latest sample, keep order_by and keep and
remove nearest.
