Following publication of the original article [1], the authors identified an error in Fig. 2. The gene BTN3A1 has Chinese text characters, and BTN3A2, BTN3A3, BTNL2, BTNL3, BTNL8, BTNL9, BTNL10, and SKINTL are not marked.

BTNL9 Expression and prognosis in LUAD. A BTNs expression panel in LUAD tissues compared with adjacent tissues in GEPIA database. B Correlation between BTNL8 and BTNL9 expression and LUAD clinical stages, N stage, and p53 mutation in the UALCAN database (BTNL8 expression compared with LUAD clinical stages (Normal-vs-Stage1, P = 1.01E-04; Normal-vs-Stage2, P = 7.08E-03; Normal-vs-Stage3, P = 1.36E-04; Normal-vs-Stage4, P = 1.78E-08), N stage (Normalvs-N0, P = 6.56E-04; Normal-vs-N1, P = 8.27E-10; Normal-vs-N2, P = 5.96E-04; Normal-vs-N3, P = 1.97E-10; N0-vs-N1, P = 3.27E-03; N0-vs-N3, P = 6.79E-04), and p53 status (Normal-vs-T P53-Mutant, P = 1.27E-06; Normal-vs-T P53-NonMutant, P = 1.80E-03). BTNL9 expression comparison with LUAD clinical stages (Normal-vsStage1, P = 1.21E-12; Normal-vs-Stage2, P = 3.60E-13; Normal-vs-Stage3, P = 2.40E-12; Normal-vs-Stage4, P = 2.25E-12), N stage (Normal-vs-N0, P = 1.08E-12; Normal-vs-N1, P = 1.85E-12; Normal-vs-N2, P = 1.02E-12; Normal-vs-N3, P = 1.67E-12; N0-vs-N1, P = 1.02E-03; N2-vs-N3, P = 3.01E-02), and P53 status (Normal-vs-T P53-Mutant, P = 1.85E-12; Normal-vs-T P53-NonMutant, P = 4.10E-12; T P53-Mutant-vs-T P53-NonMutant, P = 1.77E-04)). C Correlation between BTNL8 and BTNL9 expression with overall survival of LUAD using GEPIA database. D Correlation between BTNL9 expression and LUAD overall survival using OncoLnc, UALCAN, and KM plotter databases. ^*: P-value < 0.05; ^**: P-value < 0.01; ^***: P-value < 0.001
