Studies evaluating the associations between NK cell infiltration and overall survival. (A) Bar graph representing the distribution of conclusions from studies assessed in this review. From the 53 studies reviewed, the majority of studies (32 (59.3%)) reported significantly improved OS, 21 (38.9%) reported no significant impact on survival and one (1.9%) reported significantly poorer OS. (B) When p-values were provided (y-axis, line at 0.05) we noted them on this visualization scatter graph organized by tumor type (x-axis). Those that did not provide p-value are included above the graph. Dot size indicates the number of patients in each study (or arm of study when applicable).
