I don’t know. Looks like the control group declined almost as quickly—and had more than twice as many with fevers:

But look at the Conclusion of the study you showed ( copy and paste from the study results ):
_____________________________________
Treatment with NONS in this trial was found to be effective and safe in reducing the viral load in patients with mild, symptomatic COVID-19 infection.
Patients with recent disease onset were enrolled in the trial to evaluate the effect of early intervention with
NONS on SARS-CoV-2 RNA load. Patients in the NONS treatment arm demonstrated viral loads, as determined from PCR testing of nose and throat swab sampling, that were lower at days 2 and 4 by a factor of 16.2 than those on placebo, and symptom resolution was also found to be faster on NONS treatment than on placebo in
this study.
Lower SARS-CoV-2 RNA loads in patients with NONS may be
beneficial in the prevention of SARS-CoV-2 transmission.
It has been described that higher viral loads in patients with SARS-CoV-2 earlier than SARS-CoV may have contributed to greater difficulties in reducing the onward transmission.8 Furthermore, it has been
observed that the risk of symptomatic COVID-19 was associated with the SARS-CoV-2 RNA levels of contacts and incubation time was shortened in a dose-dependent manner.
Accelerated SARS-CoV-2 clearance with NONS may reduce symptom duration, decrease infectivity period, reduce hospital admissions, and lower disease severity. Consequently, this study could be used as supporting evidence for emergency use of NONS for patients with mild COVID-19 infection.

I’ll take the result of this study as a ‘YES’, it can be used as an effective weapon among others against Covid-19.
