Hello everyone,
I have some questions.
Writing a paper and trying to determine what is study methodology.
1. Study was conducted over 1 year period, they included hospitalized patients poisoned with organophosphates and while they were hospitalized (mean time of hospital stay was 7 days) doctors conducted tests and observed patients if they will develop intermediate syndrom. There was no control/comparative group. What kind of study is that?
Cross sectional- I think not, it is longer lasting. CC- there is no control group. Cohort? Professor remarked meit cannot be cohort if there was only 50 patients? I have no clue.
2. Doctors retrospectively gathered info about acutely poisoned patients for last 3 years and invited these patients to come for neuro evaluation (mean time between evaluation and hospitalization= 2 years).
Is this cross sectional design?
3. A study of 30 acutely poisoned people plus two control groups (healthy people and paracetamol poisoned people) in period of a year and a half; doctors did test at the day of hospital discharge to determine effects of poisoning on neuro system and repeated this test 6 months after hospital discharge.
What kind of study is that? Can it be CR and if yes, why- we have two control groups?
Thank you for you help, I am so lost. I know basic principles of studies (CO, CR, CC) but am still confused interpreting some of these clinical studies.
