Additional file 1: of Opioid doses required for pain management in lung cancer patients with different cholesterol levels: negative correlation between opioid doses and cholesterol levels

A list of current patients’ information. The records of 282 patients were listed after removing primary information. ID was the reference number provided by the authors for easier accession. “Chol level” represented the serum cholesterol level measured and recorded. “Year” represented when the initial diagnosis of cancer was made. “Initial dose”, “stable dose” and “converted dose” represented the initial dose opioid administration, the final dose of opioids used for analysis and the dose when converted to equivalent oxycodone hydrochloride, respectively. The “increased” column, “1” or “0” were used to represented that “stable dose” was higher than “initial dose”. If the patient has one or multiple additional measurement of cholesterol during the first month after opioid administration, the cholesterol level with largest difference from initial cholesterol level was selected, recorded in “Chol level with largest difference” column, and normalized to the initial cholesterol level.
