The phrase "below the control group" is grammatically correct and can be used in written English.
It is typically used when comparing data or results to a control group, which is a group that is used as a standard or baseline for comparison in an experiment or study. Example: The results of the study showed that the experimental group had significantly lower levels of stress compared to those in the control group, indicating that the intervention was effective in reducing stress levels below the control group.
Clinically significant cognitive impairment, defined as ≥1.5 SD below the control group mean, was reported for 24% of BD I and 13% of BD II outpatients [ 16], versus 42% and 25%, respectively, in the present study.
Participants in the LH damage (LHD) group exhibited impaired language abilities compared to controls, with a significant difference between groups for the Western Aphasia Battery (WAB) [ 41] aphasia quotient, t(20) = -5.356, p =.002, and with each participant in the LHD group scoring more than one standard deviation below the control group mean aphasia quotient (M = 99.46; SD =.7974).
In a second study by Pernet et al. (2009b), two predictors of dyslexia were found using a classification approach: the right lentiform nucleus and the right cerebellar declive with dyslexics falling either above or below the control group's 95%% confidence interval boundaries.
However, in a study by Pernet et al. (2009b), using a classification approach, the right cerebellar declive was one of the two best predictors of dyslexia, with dyslexics falling either above or below the control group's 95%% confidence interval boundaries.
The recognition rates of two prosopagnosic subjects (BT and LO) were still one standard deviation below of the control group's mean (Figure 2B).
Because some treatments resulted in far fewer colonies (see below) than the control group, the numbers of colonies that were analyzed among the different treatment groups varied from group to group.
The ICER ratio for CSII pumps remained below the threshold value when the difference in HbA1c level was below 0,42% in the control group and 1,30% in the active group.
tests, as opposed to about 20percentt scoring below 70 in the control group.
The maximum lifespan value for each experimental group was below that of the Control group (Table 1).
In the group of seven patients with low perforin levels in NK cells, only three had NK cytolytic activity below 2SD of the control group.
The patients in the intervention group are given the QPS, a list of 50 specific questions (see below); those in the control group are given a control sheet on which to write the questions they would like to ask.
