Studies showed that dentists graduated from different countries, or even from different dental schools in one country, may have different clinical decisions for the same clinical condition.

Studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover.

Studies of CIAT have shown that further improvement is possible even after a patient has reached a " plateau " period of recovery.

Studies have shown that while test scores have improved over time, the improvement is not fully correlated with latent factors related to intelligence.

Studies have shown hydrocodone is stronger than codeine but only one-tenth as potent as morphine at binding to receptors and reported to be only 59 % as potent as morphine in analgesic properties.

Studies of Charles Darwin's notebooks have shown that Darwin arrived separately at the idea of natural selection which he set out in his 1859 book On the Origin of Species, but it has been speculated that he may have had some half-forgotten memory from his time as a student in Edinburgh of ideas of selection in nature as set out by Hutton, and by William Charles Wells and Patrick Matthew who had both been associated with the city before publishing their ideas on the topic early in the 19th century.

Studies have shown that heterosexual men and lesbians have different standards for what they consider attractive in women.

Studies by doctors have also shown in Hong Kong that the game is beneficial for individuals suffering from dementia or cognitive memory difficulties, leading to the development of mahjong therapy.

Studies examining the role of pro-and anti-apoptotic factors support this model ; for example, the anti-apoptotic factor Bcl-2 has been shown to interact with IP3Rs to reduce Ca < sup > 2 +</ sup > filling of the ER, leading to reduced efflux at the MAM and preventing collapse of the mitochondrial membrane potential post-apoptotic stimuli.

Studies have shown that the abundances of these light elements are much lower than models of stellar evolution predict.

Studies of bacteria frozen in Antarctic glaciers have shown that DNA has a half-life of 1. 1 million years under such conditions, suggesting that while life may have potentially moved around within the Solar System it is unlikely that it could have arrived from an interstellar source.
