During exposure periods, we observed an average decrement of approximately 12% in the standard deviation of all normal-to-normal heart beat intervals (an estimate of overall HRV).
Results showed an average decrement of 37% (P < 0.0001, Mann–Whitney) during the first year and 40% (P < 0.0001, Mann–Whitney) for the second year.
Trasande's linear model originally used a dose response relationship of 0.59 1.24 IQ point decrements for every 1-μg/L increase in cord blood mercury concentration, with an average decrement of 0.93 IQ points (Trasande et al. 2005).
Patients who were code positive at hospital admission also demonstrated an average decrement of 8.7 mmol/l in serum sodium from a baseline value, the latter taken at a median of 29 days prior to hospital admission.
Conversely, 2/5 of KI mice and 12/18 KO mice had a positive test (≥10% decrement), with an average decrement in KO mice of 11.5±1.5%, compared with an average value of 2.0±0.9% for WT (P=0.0002).

The median decrement in all patients was 66% (range 0 100%); expressed as absolute amounts this resulted in a median decrement of 3.4 g (range 0 21 g).
These decrements consisted of average decrements of −5.6 % for the squat, −4.8 % for the bench press, and −4.5 % for total strength compared to the HMB-FA group, whom had average decrements in strength of −0.6 % for the squat, −1.0 % for the bench press, and −0.4 % for total strength.

After an initial and continuous increase between 1994 and 2001 [ 1], the annual reports from EARSS (1999 2007) described the isolation of MRSA from bloodstream infections in 1999 as 40%, but, unlike the trend in other European countries such as Great Britain or Greece, a constant small average decrement was registered in the 2001 2007 period, reaching an average value of 33.7% in 2007.
