Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 In AREDS, participants in the highest fish intake quartile had lower odds of cognitive impairment than those in the lowest quartile (OR = 0.36 for 3MS, P = .001). → Keenan Tiarnán D. 2020
q3 i2 In AREDS2, participants in the highest fish intake quartile had lower odds of cognitive impairment than those in the lowest quartile (OR = 0.50 for TICS-M, P < .0001). → Keenan Tiarnán D. 2020 (2)
Evidence¶
Keenan Tiarnán D. 2020¶
Keenan Tiarnán D., Agrón Elvira, Mares Julie A., Clemons Traci E., van Asten Freekje, Swaroop Anand, Chew Emily Y.; AREDS and AREDS2 Research Groups. (2020). Adherence to a Mediterranean diet and cognitive function in the Age-Related Eye Disease Studies 1 & 2. Alzheimer's & Dementia. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8328271/
q3 · i2 · associational · r3
Cross-sectional component analysis in AREDS examining fish intake quartiles and cognitive impairment. The article reports OR = 0.36 (P = .001; 3MS) and OR = 0.54 (P = .001; composite) for quartile 4 versus quartile 1.
"In AREDS, the odds ratios for cognitive impairment, in quartile 4 (vs 1), were 0.36 (P = .001; 3MS) Figure 3A and 0.54 (P = .001; composite) Figure 3B."

Cross-sectional component analysis in AREDS2 examining fish intake quartiles and cognitive impairment. The article reports OR = 0.50 (P < .0001; TICS-M) and OR = 0.54 (P = .001; composite) for quartile 4 versus quartile 1.
"In AREDS2, the equivalent odds ratios were 0.50 (P < .0001; TICS-M) Figure 3E and 0.54 (P = .001; composite) Figure 3F"
