Gemcitabine combinations may leads to lower overall survival ‐ Gemcitabine plus other combinations of chemotherapy compared with gemcitabine alone (low certainty).
Combination probably leads to lower overall survival compared with single‐agent chemotherapy (moderate certainty).
5‐FU/cisplatin/anthracycline combinations may leads to lower overall survival compared with 5‐FU/anthracycline combinations (without cisplatin) (low certainty).
5‐FU/cisplatin/anthracycline combinations probably leads to lower overall survival compared with 5‐FU/cisplatin combinations (without anthracyclines) (moderate certainty).
Fluoropyrimidine combinations showed no clear difference in overall survival compared with fluoropyrimidine alone (low certainty).
It is very uncertain whether taxane‐platinum‐fluoropyrimidine combinations changes overall survival compared with taxane‐platinum (without fluoropyrimidine) (very low certainty).
Gemcitabine combinations leads to lower overall survival ‐ Gemcitabine plus taxane compared with gemcitabine alone (high certainty).
Gemcitabine combinations showed no clear difference in overall survival ‐ Gemcitabine plus other agent(s) compared with gemcitabine alone (low certainty).
Gemcitabine combinations showed no clear difference in overall survival ‐ Gemcitabine plus platinum agent compared with gemcitabine alone (low certainty).
Gemcitabine combinations leads to lower overall survival ‐ Gemcitabine plus fluoropyrimidine compared with gemcitabine alone (high certainty).
Gemcitabine combinations showed no clear difference in overall survival ‐ Gemcitabine plus topoisomerase inhibitor compared with gemcitabine alone (high certainty).
