The correlation between the prospective physical symptom questions index from the clinical monitoring questionnaire and the Physical Component Scale of the retrospective HRQoL for the four time periods is shown in table 4.
The Meiosis CI questions' index of difficulty ranged from 0.09 to 0.71, with the majority between 0.30 and 0.50, which is within the recommended range from 0.30 to 0.90 (Ding et al., 2006) or 0.30 0.70 (Craighead and Nemeroff, 2001).
There was a significant association between the physical symptom questions index at 4 weeks after trial entry and each of the HRQoL recall timepoints, and the correlation was strongest for the 4 weeks recall (OR 3.18; 95% CI 2.14 to 4.74; p<0.001).
The challenge, especially with models that rely on multiple-question indexes, is that their accuracy when applied to polls taken a month or more before the election is unknown.
Next question: What index to follow?
We used a validated three question screening index to identify subjects with inadequate or marginal HL [ 23].
> -wrap-foot> > -wrap-foot> > -wrap-foot> The 15 question International Index of Erectile Function (IIEF) survey was used to assess sexual satisfaction and function.
Changes between the pre- and post-intervention results were tested using the Pearson χ test for each question and index, by population group in the southern parts of Sweden.
Awareness of warning signs was assessed using open questions (to index recall) and closed questions (to index recognition).
Mark Gordon changed the rules for submitting questions on the fly (screw written-down questions on index cards, shout 'em out!), and in general came across like a boss.
