In medical studies, the efficacy of medical treatments (called interventions) is evaluated within a group of study participants. You will be given a sentence of a study report in which your task is to list the phrases that describe the intervention(s) of the study. You should list the phrase in the same order that they appear in the text, separated by commas. If no information about the interventions is mentioned, just answer with "not found". Interventions are: a specific drug, surgery, talking therapy, a lifestyle modification, control or placebo treatment. Do not include details, dosages, frequency and duration, intervention mentions that are not in an informative span of text.

[EX Q]: This study examined whether ( 1 ) postmenopausal breast cancer survivors ( BCS ) with bone loss taking 24 months of risedronate , calcium , and vitamin D had increased bone mineral density ( BMD ) at the total hip , femoral neck , L1-L4 spine , total radius and 33 % radius , and decreased bone turnover ; ( 2 ) subjects who also participated in strength/weight training ( ST ) exercises had greater increases in BMD and greater decreases in bone turnover ; and ( 3 ) subjects who also exercised were more likely to preserve ( at least maintain ) BMD .
[EX A]: risedronate, calcium, vitamin D, strength/weight training, ST, exercised

[EX Q]: Toxicities , including thromboembolism , and overall survival were similar .
[EX A]: not found
