They also analyzed data from health ministry morgue records, online obituaries and an online health ministry survey, among other sources.
Palestinian health ministry figures have repeatedly come under scrutiny in the period since Israel launched its offensive in Gaza, mostly from Israeli officials.
Even so, major health authorities such as the World Health Organization have continued to express confidence in the data provided by Palestinian health officials.
Jamaluddine said she believed the study published Thursday reflects "that the numbers put forward by the [Palestinian] health ministry are accurate," and may be conservative as opposed to an inflation of the death toll in Gaza.
As long as fighting in Gaza continues, Jamaluddine said a more thorough analysis of the death toll in the enclave would remain elusive.
