The phrase "average time to onset" is correct and usable in written English.
It can be used in contexts such as medical research, studies, or any situation where you are discussing the typical duration before a particular event or symptom appears.
Example: "The average time to onset of symptoms after exposure to the virus was found to be approximately five days."
Alternatives: "mean time to onset" or "typical onset duration".
3.5% were intubated within less than 5 days notice after admission and the average time to onset of VAP was 3.76 days.
The average time to onset of the second hit was 5 days.
Postoperative epithelial pearl formation was observed in 6 of 116 (5%) patients, with an average time to onset of 7.3 months.
Postoperative epithelial pearl formation was observed in 6 of 116 (5%) patients with an average time to onset of 7.3 months (range, 1 19 months) after the operation (Table 1).
The average time to onset of AIDS in the absence of treatment was also longer than in a previous analysis in The Netherlands, which may explain, at least in part, why we also estimated a longer time to diagnosis.
Time to onset of symptoms such as trismus was an average of 12 days.
As shown in Figure 1E, there was no difference in the growth profiles of Renca-VC and Renca-LMP2A tumors, and most importantly both profiles were similar to that of Renca-WT tumors (data not shown) in terms of average time to tumor onset and progression to MATS.
As the average time to the onset of AIDS as well as the mean residence times in a given stage decrease with the accumulation of mutant strains (cf. equation (16)) patients with dominance in X4 viral load have a worsened prognosis in this respect.
The average time to gut purge from the onset of feeding was significantly longer for the wild-type larvae fed rapamycin than those fed DMSO (mean of 7.8 days as opposed to 5.7 days; one-way ANOVA, post hoc Tukey test, P = <0.0001), and the growth rate was slower in the rapamycin group (mean of 1.65 g/day as opposed to 1.16 g/day) (one-way ANOVA, post hoc Tukey test, P = <0.0001) (Fig. 1a, d).
In the patients in this series who were demonstrated by chronic ambulatory ECoG to have independent bilateral MTL electrographic seizure onsets, the average time to document the first contralateral seizure was >5 weeks, with a range of days to many months.
