El artículo viene firmado por investigadores australianos del Menzies Research Institute, que analizaron si la exposición a hermanos pequeños ejerce un efecto protector frente a la esclerosis múltiple. Para ello estudiaron a 136 pacientes con la enfermedad y a 272 controles. Sus resultados muestran que estar en contacto durante más de 5 años con un hermano pequeño se asocia a una reducción del riesgo del 88%.
