    Conflicting evidence - a concern not only for cycle helmet research

    http://www.cyclehelmets.org/mf.html#1134

    Abstract:

    "The study of cycle helmets is beset by conflicts between case-control
    studies, which infer large benefits from helmet use by comparing
    injuries of cyclists who chose to wear helmets with those who did not,
    and data from entire cyclist populations when substantial increases in
    cycle helmet use (sometimes as a result of legislation) show that the
    benefits, if any, fall far short of those predicted by case-control
    studies.

    "Cycle helmet research is not the only area of research where such
    conflicts exist, as evidenced by an increasing number of papers in
    epidemiological journals drawing attention to this problem. There have
    been issues with studies of the effect of hormone replacement therapy
    on heart disease, vitamin supplements, antibiotics and the MMR triple
    vaccine. Findings that had appeared robust subsequently turned out to
    be unreliable or simply wrong. "

    Some other new content is in process at the moment, and several pages
    have been updated recently. I am going to talk to John about a
    "subscribe" option.

    Helmet law on Prince Edward Island

    http://www.cyclehelmets.org/mf.html#1138,

    The Prince Edward Island helmet law came into effect from 5 July 2003.
    It applies to bicyclists and their passengers of all ages, but does
    not apply to people riding tricycles.
    The penalty for an offence against the law is between CAD50 and
    CAD100. Parents are responsible for offences committed by children
    under 16 years if aware that the child did not wear a helmet.

    Compliance and enforcement
    No data available.

    Effect on casualties
    No data available.

    Effect on cycle use
    No data available.

    Cost benefit
    No data available.

    Note:
    The population of Prince Edward Island is only around 140,000, of whom
    it likely that no more than 7,000 people cycle regularly. It may
    therefore be difficult to acquire statistically-significant data by
    which to measure the effects of the helmet law.

    Careful use of diplomatic language there, but he doesn't like EN1078 one
    little bit, does he?

    [Bottom of page 3]
    "I would not write a safety helmet standard for any application that did
    not include flat /and/ spherical surfaced anvils" [his emphasis]. EN1078
    does not include the spherical anvil.

    [First column page 4]
    "Cycle helmets sold in the UK today generally offer a lower level of
    protection than those sold in the early 1990s. This is due in the main
    to the introduction of the European EN1078 standard..."

    One thing that interested me is that he says (and I'm sure he knows)
    [middle of page 4]
    "Expanded polystyrene... is /not/ known to deteriorate with age" [my
    emphasis] I though (and have said) that it did; that it became more
    brittle. It seems I'm wrong.

    [following up to myself. I know, uncool]

    I went to download the EN1078 standard myself, so I could read it.
    Unfortunately, you can't. It costs sixty four bloody quid!
