INCIDENCE AND TRENDS
It is not clear whether withholding or no disclosure of the funding
source was the result of either the lack of significant funding or
potential conflict of interest. We have included manuscripts published
in PubMed only, and other databases are excluded. It also missed some of
the data published as government reports and gazettes.[6]
Incidence and trends are studied by Seventy-six papers. uniformity was
not found in reporting the incidence rates. The incidence has been
reported from the population-based registries and trends from secondary
data as ASR and expected annual percentage change. The percentage of
patients treated represents the incidence of hospital-based studies. The
non-uniformity in reporting and predominance of hospital-based
registries lead to misrepresentation of the incidence of cancers and
Keeping Journal of Medicine had also revised its rules about conflict of
interest.[13 ]
