Reassuringly, the fact that we observed a duration-response relation and the point estimates were consistently lower with a shorter (60 and 30 days) exposure time window and grace period (that is, the likelihood of being concurrently exposed to antihypertensive drugs and NSAIDs was reduced) indicates that residual confounding was probably minimal.
Kesimci et al. added 100 mg of tramadol to 40 mL of ropivacaine 7.5 mg/mL and observed a longer duration of analgesia but did not observe an improved speed of onset of block or an increase in the duration of sensory or motor block [ 16].
Interestingly, we observed a shorter duration of aplasia in Busulfan regimens than in Melphalan protocols (or in the other chemotherapies).
Some studies have observed an average duration, 24 30 months, of response to primary hormonal treatment (Smith, 1991).
We observed a longer ECMO duration in the ECMO device colonisation group as compared to the uninfected/uncolonised ECMO device group [12 (9–20 days) vs. 5 days (5 16 days), respectively, p < 0.05].
We observed a longer ECMO duration in the ECMO-device colonization group as compared with the Uninfected/Uncolonized ECMO-device group [12 days (9-20 days) versus 5 days (5-16 days); respectively, p < 0.05].
We observed a longer ECMO duration in the ED-C group compared with the U-I/C ED group [12 days (9 20 days) versus 5 days (5 16 days), respectively, p < 0.05].
We observed a significantly longer duration of ventilation and lengths of stay in the ICU and in hospital in the RML group (P < 0.01 for all observations).
We observed a very short duration of cell division in the pericarp of LA1589 fruit (less than 5 dpa), in contrast to ~7 to 10 dpa in cultivated tomato [ 19].
Each animal was placed individually in a 5 L glass beakers, filled with water up to a height of 15 cm and were observed for a duration of 6 min.
