A systematic review and meta-analysis of the Chinese literature for the treatment of achalasia

Table 3 Pooled estimate of response rate of non-controlled trials for achalasia treatments across referenced trials

Therapy and references	Total No. of patients	Weighted response of treatment methods for achalasia (1 yr after treatment)
		Remission rate (ƥ) mean ± SE, %	Relapse rate (ƥ) mean ± SE, %	Weighted follow-up mean (range), mo
PD	667	86.6 ± 23.9	10.7 ± 21.0	26 (4-102)
HM	354	94.8 ± 10.6	1.5 ± 6.3	46 (1-178)
TM	64	92.0 ± 10.0	4.91 ± 9.0	30 (1-80)

PD: Pneumatic dilation; BoTx-PD: Botulinum toxin plus Pneumatic dilation; HM: Heller myotomy. In calculating the weighted mean response for each treatment modality (ƥ), included studies were characterized by the number of subjects included (n) and the response rate for those subjects (p). Ellipses represent scant data.
