Change in Mutans streptococci (MS) and Lactobacilli in saliva · Schoolchildren (6-9 years), high caries risk

The single stevia trial (Cocco 2019) reported a significant reduction in salivary Mutans streptococci and lactobacilli, but gave no effect size and was not GRADE-rated.

Blood pressure intervention/intensive blood pressure intervention vs placebo/standard blood pressure intervention

Change in visual loss associated with PSR: visual loss is defined by the deterioration of visual acuity of 3 lines or more with the Snellen chart · type 1 or type 2 diabetics

It is very uncertain whether blood pressure intervention/intensive blood pressure intervention changes visual acuity (loss of 3 lines or more) by 5 years compared with placebo/standard blood pressure intervention (very low certainty).
