Yes but.........
It's simple to show that the rise of LCO's has led to a diminution in accidents- this is the beauty of statistics (!)
However, possible contributions include that LCO's tend to fly newer aircraft, their fleets are all the same or very similar so you reduce the opportunities for confusion in both flying (and perhaps more important) maintenance crews. They also tend to fly more bus-stop flights a pilot is likely to do the same flight several times a day or week cp the legacy carriers who have more variety.
And the fact that most tend to fly to reasonably well equipped airfields (excluding Indonesia.) helps
Plus of course they fly so damned many airmiles - so the accidents/incidents that do happen are spread over a lot more flights/pax/kms.
