Figure Lengend Snippet: Validation data of opioids: coefficient of correlation ( R ), precision (CV%), and accuracy (bias%) at the lower limit of quantification (LLOQ) and three QC levels, recoveries (RE), matrix effects (ME), and internal standard corrected matrix effects. The quantification range was from LLOQ to 50 × LLOQ for all analytes
