The lead-in, the randomisation, and the year that followed
Three randomised withdrawal designs have tested what happens when treatment stops. Their results are consistent and they are consistently misreported.

Three randomised withdrawal designs have tested what happens when treatment stops. Their results are consistent and they are consistently misreported.
The observation that closes a facility is rarely the dramatic one.
Reported from the analysis, not from a warning notice.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The limit for a parenteral product is calculable from the dose and the body weight in two lines. Almost nobody in this trade performs the calculation.
The composition data comes from imaging substudies enrolling a few score participants at selected sites. It is the best evidence available and it is thin.
The observation that closes a facility is rarely the dramatic one.
The supplier has not disputed the finding. It has not explained the gap either.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The evidence base is thin and the document says so, which is to its credit.
A document is only as good as the chain that connects it to the material, and most chains here are two or three links longer than the paperwork admits.
The schedules in circulation, described accurately, with their evidentiary status attached.
A proper account of an operation that existed, and of what closing it cost.
Reported from the analysis, not from a warning notice.
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
The evidence base is thin and the document says so, which is to its credit.
A tour of the tissues where the receptor is expressed, and what happens in each.
The Journal has read several hundred certificates from twenty companies. We set out what the documents actually cover, and what a reader is filling in from imagination.
A proper account of an operation that existed, and of what closing it cost.
Efficacy was never the question in this appraisal. Duration of treatment was.
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
The document is four pages. Three of them are about dates.
The mechanism is well described. The variance is not.
Every degradation pathway accelerates by orders of magnitude on reconstitution, because the solvent that lyophilisation removed is the reagent most of them need.
What adding GIP activity does, on the current evidence, and what remains unresolved.
Reported from the analysis, not from a warning notice.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The route did not close because of a rule about peptides.
Two years ago we ran an anonymised version of this comparison and promised a named one. This is it, with every method printed in full.
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
The report states the gradient, the wavelength and the integration threshold, which is more than most.
The document is four pages. Three of them are about dates.
Reported from the sessions, and from the two hours afterwards.
What would make a difference is not a regulator. It is three lines on a certificate, all of which are already known to whoever wrote it.
Aseptic technique here is four steps and none of them are difficult. They are, however, routinely compressed to two.

Chromatographic software does not integrate every fluctuation in the baseline. It applies a threshold, and the threshold changes the reported purity by amounts that matter…
