just ran into other odd example of Zoterro failure ( get them to lift my block and I'll post there lol )

I ran into this,=0A=

=0A=
and toobib apparently did not fetch the pdf but used a "highwire" handler=
=0A=
that I thought by now was obsolete but apparently is vectored from the bmj =

( based on output below ). Sometimes I've seen links return html vs pdf dep=
ending on =0A=
request details but in this case it looks like toobib just made a different=
 request based=0A=
on a common web motif. =0A=
The zotero webform,  https://zbib.org/ , returned an error which is surpris=
ing considering=0A=
this is a well known domain with standard pattern.  Does their full install=
 work any better? =0A=

abstract =3D {Objectives The real-world evidence on the association between=
 vitamin D supplementation and cognitive outcomes has been scant and contro=
versial. We aimed to investigate the longitudinal association between vitam=
in D supplement use and subsequent cognitive functioning among US older adu=
lts.Design Prospective cohort study.Setting A nationally representative age=
ing cohort in USA: the Health and Retirement Study (HRS).Participants Parti=
cipants were drawn from the HRS wave 12 and included respondents who had co=
mplete data on dietary supplement use and cognitive assessment. A total of =
5065 participants (mean age: 67.5{\textpm}10.2 years, 61.6\% female, 76.6\%=
 White ethnicity) were included, of whom 2004 (39.6\%) participants were vi=
tamin D supplement users.Primary and secondary outcome measures Change in c=
ognitive function scores over 6 years of follow-up (from HRS waves 12{\text=
endash}15), estimated by linear mixed model adjusted for multiple covariate=
s.Results Compared with non-users, vitamin D users had an accelerated decli=
ne in global cognitive function (difference in the rate of change: -0.052 p=
oints/year; 95\% CI -0.092 to -0.013, p=3D0.010) and in executive function =
score (difference: -0.021 points/year; 95\% CI -0.037 to -0.005, p=3D0.010)=
. Sensitivity analysis suggested that accelerated cognitive decline was onl=
y observed among supplement users with normal baseline serum 25(OH)D level =
(p=3D0.004), but not the group with insufficient/deficient levels (p=3D0.82=
6).Conclusions Our findings do not support vitamin D supplementation as a m=
eans of preventing or slowing cognitive decline in older people with adequa=
te vitamin D status. While healthcare providers should encourage adequate v=
itamin D intake from dietary sources and moderate sun exposure, caution sho=
uld be taken when recommending such supplements to older adults without a c=
lear indication for it.Data are available in a public, open access reposito=
ry. The datasets generated and/or analysed during the current study are ava=
ilable from https://hrs.isr.umich.edu/.},=0A=
