We cannot evaluate the binuclear and strontium carbonate surface reactions with this model, because data are insufficient for calibration (Equations 6 11).
Because data was insufficient to conduct quantitative analyses, we summarized findings qualitatively.
Because data are insufficient to determine what common cross-disorder etiological factors might exist, alternative phenotypes should be explored.
Because data are insufficient regarding the effect of metformin on renal function in higher risk populations, such as after STEMI, we examined whether metformin itself could adversely affect renal function and consequently increase the risk of developing lactic acidosis.
We chose to not include further interactions when obtaining the average effect of each combination of predictors in Eq. (1), because the data were insufficient (e.g., not all temperature and latitude combinations are available), and because visual interpretation of functions of three or more variables is difficult.
Because the data were insufficient and the various studies utilized different clinical activity indices, our analysis failed to stratify patients by disease activity.
Among the 7,734 eligible children, 161 caretakers refused to participate (2.1%), 174 caretakers could not be contacted (2.3%), and 144 caretakers completed interviews but were excluded from analysis, because either data were insufficient to calculate the child's age or the calculated age was > 59 months, leaving 7,259 analyzable interviews.
For 5 patients clinical data were insufficient because they came from abroad and did not have adequate follow-up in our center.
We combined all persons >10 years of age into a single group because Hib colonization and incidence data were insufficient to reliably model more age groups within this broad category.
