Laser ablation vs radiofrequency ablation

Cancer‐related mortality at maximal · people with early‐ or very early‐stage hepatocellular carcinoma ineligible for surgery

It is very uncertain whether laser ablation changes cancer‐related mortality at maximal compared with radiofrequency ablation (very low certainty).

Laser ablation vs radiofrequency ablation

Serious adverse events (number of participants) · people with early‐ or very early‐stage hepatocellular carcinoma ineligible for surgery

It is very uncertain whether laser ablation changes serious adverse events (number of participants) compared with radiofrequency ablation (very low certainty).

Endovenous laser ablation (EVLA) vs conventional surgery

Recanalisation or persistence of reflux at 6 weeks · people requiring intervention for short saphenous vein varices

Endovenous laser ablation probably leads to lower recanalisation or persistence of reflux at 6 weeks compared with conventional surgery (moderate certainty).

Endovenous laser ablation (EVLA) vs conventional surgery

Recurrence of reflux at 1 year · people requiring intervention for short saphenous vein varices

Endovenous laser ablation may leads to lower recurrence of reflux at 1 year compared with conventional surgery (low certainty).

Endovenous laser ablation (EVLA) vs conventional surgery

Recurrence · people requiring intervention for short saphenous vein varices

Endovenous laser ablation showed no clear difference in clinical evidence of recurrence after 1 year compared with conventional surgery (low certainty).

Endovenous laser ablation (EVLA) vs radiofrequency ablation

Technical success · people with GSV incompetence

Endovenous laser ablation (EVLA) showed no clear difference in technical success (< 5 years) compared with radiofrequency ablation (RFA) (moderate certainty).

Endovenous laser ablation (EVLA) vs SFJ ligation and stripping (HL/S)

Technical success · people with GSV incompetence

Endovenous laser ablation (EVLA) may leads to higher technical success (< 5 years) compared with SFJ ligation and stripping (HL/S) (low certainty).
