Genetically predicted periodontitis vs Without periodontitis (lower genetic liability)

Lacunar stroke · European-ancestry adults

Genetically predicted periodontitis was associated with modestly higher odds of lacunar stroke (OR 1.24); ungraded MR, though the FDR-adjusted P was 0.064 for the primary IVW-FE method (ML-adjusted P 0.037).

Preoperative antibiotics vs placebo

Occurrence of postoperative infection - 4 weeks · People requiring retreatment of periapical lesions (failed root canal therapy)

It is very uncertain whether preoperative antibiotic prophylaxis changes occurrence of postoperative infection - 4 weeks compared with placebo (very low certainty).

PDHA program with robust prevention vs PDHA program or PDHA program with intensive staffing

Tooth decay-free children · Alaska children aged 5 to 18 years

The robust prevention PDHA model was projected to yield more than 50% tooth decay-free children versus 8% with other PDHA models, without a GRADE rating.
