Many effect measures used in clinical trials are problematic because they are differentially understood by patients and physicians.
Qatar now tops many of the measures used to assess a country's well being.
Many of the measures used to assess the components were developed in low-stakes settings, such as research studies or self assessments, where there were few, if any, consequences attached to a particular score.
Many of the measures used in research have limited feasibility for use in clinical practice.
However, it is worth noting that many of the measures used a three-point Likert scale (e.g., PSC, SDQ).
Finally, a fourth problem is that many of the measures used to determine the effect of treatment are assessed differently from lab to lab, making comparison of different treatments effectively impossible.
In the assessment of patients with RA, many measures are used to assess disease severity including elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), swollen/tender joint count at onset, rheumatoid factor, antibodies to citrullinated proteins, extra-articular features or erosions at presentation (reviewed in [15]).
Many measures were used across all three time frames.
However, many of the outcome measures used in prognostic and antibiotic studies are not validated and do not capture features of outcome that are important to patients.
