Publikationer

 

Här samlas vetenskapliga publikationer där SRQ-data har använts i forskningen. Det är viktigt att SRQ får information om alla publikationer som genereras från SRQ-data, eftersom SRQ är skyldig att redovisa vilka forskningsresultat som registret har bidragit till.

Om du har publicerat forskning som använt SRQ-data ber vi dig därför att skicka information om detta till SRQ:s kansli.
