q3 · i? · quant-synthesis · r1

Weighted pooled success rates from a random‐effects meta‐analysis (DerSimonian and Laird) of the three studies eligible for meta‐analysis, covering 771 roots. The review reports "teeth with vital pulps (87.8%)" versus necrotic pulps at 65.6%; no standardized effect size is printed.

"Success rates were notably greater for teeth with vital pulps (87.8%) compared with necrotic pulps (65.6%)."
