PROCESS EVALUATION Analysis Factor analyses to create composite My Lifestyle Questionnaire variables An exploratory factor analysis (EFA) was conducted on half of the baseline MLQ data set, followed by a confirmatory factor analysis (CFA) (in the remaining data set) to generate composite variables that loaded together and could be taken into the subsequent mediation analyses. We adopted a parsimonious approach to the construction of these variables, summarising across theoretically derived and HeLP-specific MLQ items (see Appendix 18). Table 43 shows the five statistically generated composite variables from the factor analyses, the MLQ constructs that they came from, the questions that fed into the constructs and the corresponding score ranges.

SEM allows the assessment of the relationships among a set of variables using multi-item scales, multiple variables and multiple 129 130, outcomes. The variables included in the mediational analyses are baseline and 12-month BMI SDS, gender, school IMD score, class size and baseline and 18-month energy-dense snacks and negative food markers, as well as the five composite variables from the MLQ (see Table 43). The independent variable is the allocation group: intervention versus control. There are two dependent variables: the number of weekday energy-dense snacks consumed per day at 18 months and the number of weekday unhealthy foods consumed per day (negative food markers) at 18 months. These were the secondary outcome variables from the main trial that had statistically significant between-group differences. We took a parsimonious approach to the modelling exercise and hence did not select the two other statistically significant secondary outcomes (the average number of energy-dense snacks and negative food markers foods consumed across the whole week at 18 months). Furthermore, we did not select healthy snacks at the weekend as the adjusted between-group difference from the linear random-effects regression model was not statistically significant (mean difference 0.
0 It is important to recognize that lead I (and to a lesser extent aVL) are right -to- left in direction buy glyburide 5 mg on line diabetes symptoms hypo. Also, lead aVF (and to a lesser extent leads II and III) are superior -to- inferior in direction. The diagrams on the next page further illustrate the frontal plane and chest lead hookup. Precordial lead placement V1: 4th intercostal space (IS) adjacent to right sternal border V2: 4th IS adjacent to left sternal border V3: Halfway between V2 and V4 V4: 5th IS, midclavicular line V5: horizontal to V4; anterior axillary line V6: horizontal to V4-5; midaxillary line (Note: in women with large breasts, V4-6 leads should be placed under the breast surface as close to the 5th IS as possible) 6 2. Like the approach to a physical exam, it is important to follow a standardized sequence of steps in order to avoid missing subtle abnormalities in the ECG tracing, some of which may have clinical importance. The 6 major sections in the "method" should be considered in the following order: 1. MEASUREMENTS (usually made in the frontal plane leads): Heart rate (state both atrial and ventricular rates, if different) PR interval (from beginning of P to beginning of QRS complex) QRS duration (width of most representative QRS) QT interval (from beginning of QRS to end of T) QRS axis in frontal plane (see "How to Measure QRS Axis" on p 8) 2. CONDUCTION ANALYSIS: "Normal" conduction implies normal sino-atrial (SA), atrio-ventricular (AV), and intraventricular (IV) conduction. WAVEFORM DESCRIPTION: Carefully analyze each of the12-leads for abnormalities of the waveforms in the order in which they appear: P-waves, QRS complexes, ST segments, T waves, and…. FINAL ECG INTERPRETATION: This is the conclusion of the above analyses. Occasionally the term "borderline" is used if unsure about the significance of certain findings or for minor changes. Examples of "abnormal" statements are: Inferior MI, probably acute Old anteroseptal MI 7 Left anterior fascicular block (LAFB) Left ventricular hypertrophy (LVH) Right atrial enlargement (RAE) Nonspecific ST-T wave abnormalities Specific rhythm abnormalities such as atrial fibrillation Example of a 12-lead ECG interpretation using the “Method”: Mearurements: Rhythm (s): Conduction: Waveform: Interpretation: A= 67 V=67 Normal sinus Normal SA, rS in II, III, aVF; Abnormal ECG: PR=180 ms rhythm AV, and IV SIII > SII ; Left Anterior Fascicular Block QRS=90 ms conduction Small q in I, aVL; QT=400 ms Poor R progression Axis= -50 V1-4 6. These changes may have important implications for clinical management decisions.
