Desirable Effects of Helmet Use
The effects of cycle helmets have been studied mainly through case-control studies and time-trend analyses. Case-control studies usually show a substantial protective effect on head injuries as do most meta-analyses of them. Time-trend analyses usually show less or no protective effect. No randomized controlled trials have been done on the subject.

Famous quotes containing the words desirable, effects and/or helmet:
“It is neither possible nor desirable to be always attuned to the moods of children because this thwarts their need to test and enrich their individuality by standing up to adult authority. What is possible and desirable is to cultivate an attitude of partnership: to be willing to listen, acknowledge that parents and children at times have different goals, try to reconcile the differences, and agree to disagree if this is not possible.”
—Alicia F. Lieberman (20th century)
“Whereas Freud was for the most part concerned with the morbid effects of unconscious repression, Jung was more interested in the manifestations of unconscious expression, first in the dream and eventually in all the more orderly products of religion and art and morals.”
—Lewis Mumford (1895–1990)
“She left the web, she left the loom,
She made three paces through the room,
She saw the water-lily bloom,
She saw the helmet and the plume,
She looked down to Camelot.
Out flew the web and floated wide;
The mirror cracked from side to side;
“The curse is come upon me,” cried
The Lady of Shalott.”
—Alfred Tennyson (1809–1892)
