Notes

1. pain prevalence stratified by population type (workers/general/elderly), for each pain type (8); "Pain Tables by Type global review 12 aug TJ.docx"
2. gender odds ratio meta analysis; need number of subjects, crude (unadjusted) odds ratio, proportion of males, overall prevalence of pain, and consistent pain type (e.g., "All"); "gender global review 12 aug TJ.docx"
3. depression/anxiety/PTSD odds ratio meta analysis; need same as above for gender odds ratio meta analysis; "Depression, anxiety, ptsd~1.docx‎"
4. other (rural/education/smoking/income/mental illness) odds ratio meta analysis; need same as above for gender odds ratio meta analysis; "other associations global review 12 aug TJ.docx"
5. odds ratio for disability in pain versus no pain; need all items listed above for each study; this outcome is difficult because disability is not well defined by each study; "disability table global review 12 aug TJ.docx"
6. age odds ratio quantitative meta analysis is difficult because studies do not use the same age categorizations; "Age table global review 12 aug TJ.docx"
7. do not use "global review spreadsheet ...xlsx"

1. review LBP papers in mood (depression) tables, try to identify unadjusted odds ratio

Notes from 8/28/2014 (Xue)

1 Download LBP studies (six) which may have association study with mood (depression). There is one study by Tavafian.2008 which is a focus group study, this one was not included in the excel file but available in the word document. Not sure whether we should consider this study or not.

Author/Year	Mood+ LBP+	Mood- LBP+	Mood+ LBP-	Mood- LBP-	Crude Odds Ratio	Time (min)	Notes
Sharma et al. (2003)	1738	856	190	810	8.65	12	"psychosocial issues" or "psychological issues"; paper is very short
Altinel et al. (2008)	72	966	30	967	2.40	8	"depression"; adjusted OR: 1.846
Bejia et al. (2005)	75	101	56	118	1.56	15	"Distributed psychological profile" Adjusted OR 1.93
Phila Pa et al. (2010)	93	57	232	518	3.64	10	"depression",adjusted OR 3.44: paper also talk about anxiety and PTSD
Tavafian et.al (2008)	X	X	X	X		8	Focus group study, counts for cells not identified.only information available is there are totally 24 subjects in the study
Vuuren et.al (2005)	8	25	11	66	1.92	10	Different definition for LBP, (used FRI definition), "Fear avoidance belief" to measure the mood disorder, adjusted OR, 2.35

TODO

1. pain prevalence meta-analysis is easiest, once data are cleaned; Xue will coordinate with Tracy and student in this regard
2. the gender association meta-analysis is the most clean, but need to get all of the required data; Xue will give an example of the required data
3. if the depression/anxiety/PTSD outcomes are well defined, then these meta-analyses can be done as well; still need required information
4. disability and age are both problematic; recommend examining these last, or omitting
