Types of selection bias
*In appropriate selection OR POOR RETENTION OF SUBJECTS 1. Ascertainment/sampling bias- sampled population different from target population 2. Nonresponse bias- high number of nonresponders cause errors if nonresponders act differently from responders 3. Berkson bias- only study inpatient/hospitalized patients, not applicable to general population 4. Prevalence/Neyman bias- exposures that happen long before assessment can cause study to miss diseased patients that die early or recover 5. Attrition bias- significant loss of study participants cause bias if those lost to follow-up differ significantly from remaining subjects
Types of observational bias
*Inaccurate classification, measurement of disease, exposure, or other variable 1. Recall bias- subjects with negative outcomes more likely to report exposure than subjects with out negative outcomes 2. Observer bias- observers misclassify data because of individual differences in interpretation OR preconceived expectations regarding study 3. Reporting bias- subjects over or under report exposure history because of perceived stigma 4. Surveillance/detection bias- risk factor itself causes increased monitoring in exposed group vs. unexposed group, increasing chances of catching a disease

A 72-year-old woman comes to the physician because of an increase in abdominal girth over the past 2 months. She has had a 3.6-kg (8-lb) weight gain during this period despite being unable to finish any meal. She has one martini daily after her 3-mile walk. She underwent lumpectomy and radiation therapy for stage I breast cancer 4 years ago and has been treated with tamoxifen since then. Abdominal examination shows a fluid wave. Pelvic examination shows an 8-cm, fixed, nontender mass in the cul-de-sac. Laboratory studies show normal findings. Which of the following is the most appropriate next step in management? A) Intravenous albumin therapy B) Intravenous antibiotic therapy C) Intravenous cisplatin and paclitaxel therapy D) Oral angiotensin-converting enzyme (ACE) inhibitor therapy E) Oral spironolactone therapy F) Therapeutic paracentesis G) Exploratory laparotomy
The main knowledge gap is to know that ovarian masses can present with ascites, and that an ovarian mass of 8-cm (which is quite large!) needs to be removed asap. There is a high likelihood that this is cancer, and it needs to be staged, which can only be accomplished with an ex-lap. Remember that we do NOT biopsy these masses (for risk of seeding among other reasons). She drinks only 1 martini a day (most med students drink more than that), so her ascites is likely not due to alcoholic liver disease. A therapeutic paracentesis might be an ok thought, but she's going to ultimately need surgery asap, so you should skip the paracentesis and go to surgery. Furthermore, we don't even know exactly how much fluid she has in her belly, something they should probably tell you if they want you to choose paracentesis. She has no signs of infection, and no other pertinent history pointing to anything else, which should help you eliminate other choices.
