Band ligation vs no intervention or a sham procedure

All‐cause mortality · children with portal hypertension and large oesophageal varices, without previous gastrointestinal bleeding or beta‐blocker treatment

It is very uncertain whether band ligation changes all‐cause mortality compared with sham or no intervention (very low certainty).

Induced hypertension vs placebo or no intervention

Proportion of participants with ≥ 1 serious adverse events · people with acute subarachnoid haemorrhage

It is very uncertain whether induced hypertension changes proportion of participants with ≥ 1 serious adverse events compared with placebo or no intervention (very low certainty).

Gamified mobile health app vs Nongamified intervention

Regular use rate · Children or adolescents

One RCT reported a 72.4% regular-use rate with a gamified mobile health app versus 48.3% with a nongamified intervention; no GRADE assessment was reported.

Consumption of xylitol chewing gum by women (mothers) vs no intervention

Change in Mutans streptococci (MS) count in saliva · healthy people

Xylitol significantly reduced Mutans streptococci in saliva compared with no intervention (SMD -1.47, 95% CI -1.94 to -0.99; 3 trials), though heterogeneity was very high (I2=98%); not GRADE-rated.

Er:YAG laser irradiation of sound enamel before acid challenge vs No anticaries intervention (untreated enamel)

Demineralised lesion depth · Human tooth enamel specimens, sound/intact (in vitro)

Er:YAG laser irradiation significantly reduced demineralised lesion depth versus untreated control (SMD -0.55, 95% CI -0.97 to -0.12; 3 in vitro studies, I2=62%; ungraded).

Er:YAG laser irradiation of sound enamel before acid challenge vs No anticaries intervention (untreated enamel)

Enamel surface microhardness · Human tooth enamel specimens, sound/intact (in vitro)

In sound enamel, Er:YAG laser irradiation significantly increased surface microhardness after acid challenge versus untreated control (SMD 2.41, 95% CI 0.70 to 4.12; 3 in vitro studies; ungraded).

Silver diamine fluoride (SDF) vs Placebo, control, and/or other interventions

Caries arrestment at the individual (patient) level · Children and adults without systemic diseases affecting dental health

SDF showed a higher caries-arrestment proportion at the individual level, but the reported difference was not statistically significant.

Intervention not reported

Pegylated interferon beta‐1a (Direct evidence; 1 RCT; 1512 participants) · Patients with RRMS Interventions: Azathioprine, daclizumab, fingolimod, glatiramer acetate, Immunoglobulins, interferon beta 1a ‐1b,…

The intervention may leads to lower pegylated interferon beta‐1a (Direct evidence; 1 RCT; 1512… (low certainty).
