Fig. 6From: Simultaneous placement of short implants (≤ 8 mm) versus standard length implants (≥ 10 mm) after sinus floor elevation in atrophic posterior maxillae: a systematic review and meta-analysisSubgroup analysis in sinus floor elevation methods of survival rate. The p value of subgroup analysis was higher than the analysis of total studies, showing that the different methods of sinus floor elevation might be a reason for heterogeneity.
