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).
