The pain scores and the proportion of patients experienced moderate-to-severe pain during follow-up. Abbreviations: ESPB, erector spinae plane blocks; SAPB, serratus anterior plane blocks. The middle line in the plot boxes represents the median values, while the boxes indicate the interquartile range. The whiskers extend to the most extreme observed values within 1.5 times the interquartile range of the nearer quartile and the dots represent observed values outside the range.
