Data and analysis code for: Adding just-in-time simulation rehearsal before clinical flexible bronchoscopic intubation and early skill acquisition by anesthesia residents

De-identified data and R analysis code for the manuscript "Adding just-in-time simulation rehearsal before clinical flexible bronchoscopic intubation and early skill acquisition by anesthesia residents: a propensity score-matched retrospective cohort study" (BMC Medical Education, under revision). The archive contains one row per assessment for the 40 matched residents (4 supervised clinical intubations each), with both raters' independent global rating scale and checklist scores recorded before consensus and the consensus scores; the matching covariates of the matched residents and of the 61-resident pre-match pool; the patients' difficult-airway criteria; the training cohort of each resident with days since the first assessed intubation; the rater-level entries corrected before the first revision; a codebook; and the R scripts for all analyses. See README.txt for the layout. No patient or resident identifiers and no calendar dates are included.
