The phrase "joint index" is correct and usable in written English.
It is used to describe a joint system of categorizing and organizing information. For example, a library might have a joint index of all of its books, which allows patrons to easily search for any title.
For example, a joint index could be defined as follows: JI=sum_m{w}_mcdot sum_jleft({w}_{m, j}cdot {C}_jright) where w m,j is the weight of characteristic C j (e.g. pedestrian-vehicle conflict points) associated to general macro-characteristics MC (e.g. design); w m is the weight of general macro-characteristics MC contributing to the general safety goal.
The radiographic joint index represented the sum of both hind paws with a maximum score of 6.
Analysis of different serial and parallel combinations showed that a joint index combining all four indices in parallel resulted in better predictive value than any single index.
A joint index that combined R and MA in parallel showed optimal predictive value for hemorrhage and was superior to any single TEG index alone.
Naredo et al. assessed within scan intra-reader reliability with a resultant excellent ICC value of 0.99 [ 10] for summated 4-point semi-quantitative PDUS imaging of 28 joints, called the 'overall US joint index for power Doppler signal'.
Morgan et al. used discrete measures of activity, such as the joint index for tenderness or swelling and grip strength, and also found no difference between 5 mg and 27.5 mg folic acid per week [ 15].
For assessing disease activity, the disease activity score for 28 joint indices (DAS-28) was calculated [ 21].
DAS-28, disease activity for 28 joint indices score; ESR, erythrocyte sedimentation rate; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; TC, total cholesterol.
Lipid profiles, disease activity for the 28 joint indices score (DAS-28) as well as ACR 50% response criteria were determined for all patients.
In addition, the predictive value of the joint indices was superior to any single index alone, with a sensitivity of 85.9%, specificity 34.7%, and area under the ROC curve of 0.61.
Disease activity was assessed by measuring the disease activity for 28 joint indices score (DAS-28) [ 25], while the clinical response was evaluated according to the ACR 50% response criteria [ 26].
