Risk ratio for the association between TP53 status and response to neoadjuvant chemotherapy.

Subgroup analysis was performed when there were at least two studies in each subgroup. N, number of studies; Ph, p value of Q-test for heterogeneity. *For studies using both clinical and pathological responses, we used the pathological response data, but also examined the clinical response data, and found similar results (data not shown). #One study (Oshima et al. [15]) used both genomic sequencing and DNA microarray analysis for gene measurement; we used genomic sequencing data, but also also examined the DNA microarray data, and found similar results (data not shown).
