Across the two trials , rates of confirmed hypoglycaemia ( SMBG < @ mmol/L or severe -LSB- needing assistance -RSB- ) ranged from @ to @ episodes per patient-year and were similar for IDeg @TW ( AM ) and IGlar OD ( estimated rate ratio -LSB- ERR -RSB- @ , @ % CI @-@ @ ) , but higher for IDeg @TW ( PM ) than for IGlar OD ( ERR @ , @-@ @ ) .
