In all, 679 participants received one of 11 different cerumenolytics. One trial compared active treatments with no treatment, three compared active treatments with water or a saline 'placebo', and all nine trials compared two or more active treatments. Eight trials included syringing as a secondary intervention.
Capybaras do not follow the same route while grazing on consecutive days. Capybaras are semi-aquatic mammals found wild in much of South America (including Panama, Colombia, Venezuela, Brazil, Argentina, French Guyana, Uruguay, Peru and Paraguay) in dense rainforest areas near bodies of water.
Most rodents are much smaller than capybaras. The second largest rodent is the mara or Patagonian cavy. Maras are about a foot tall and weigh about 25 pounds. They differ from capybaras in that they are adapted for living for living in dry grasslands, so their bodies resemble those of small deer.
