***apologies for cross-posting***
Hello, everyone. I'd like your wise opinion. I'm looking over an article
that was appraised by the ACP Journal Club. ACP noted that the allocation
concealment was unclear. However, looking at the original article, it seems
otherwise. "The [random-number] sequence was generated by one of us, who
enclosed the numbers indicating the assignments in sealed, numbered
envelopes." Why didn't ACP consider this concealed? Was it because the
article didn't specify if the envelopes were opaque?
