# Clinical Research Guide

A skill for designing clinical studies and reporting results according to established guidelines. Covers randomized controlled trials (CONSORT), observational studies (STROBE), diagnostic studies (STARD), and systematic reviews (PRISMA).

## Study Design Selection

### Hierarchy of Evidence

```
Systematic Reviews / Meta-analyses
       |
Randomized Controlled Trials (RCTs)
       |
Cohort Studies (prospective)
       |
Case-Control Studies
       |
Cross-Sectional Studies
       |
Case Reports / Case Series
       |
Expert Opinion

Choose the design that best answers your research question
given ethical, practical, and resource constraints.
```

### Design Decision Framework

```python
def select_study_design(research_question: str,
                        can_randomize: bool,
                        outcome_prevalence: str,
                        time_constraint: str) -> dict:
    """
    Guide selection of clinical study design.

    Args:

        can_randomize: Whether randomization is ethical and feasible
        outcome_prevalence: 'common' or 'rare'
        time_constraint: 'short', 'medium', or 'long'

## CONSORT for Randomized Trials

### Essential CONSORT Checklist Items

```
Title and Abstract:
  - Identify as randomized trial in the title
  - Structured abstract with trial design, methods, results, conclusions

Methods:
  - Trial design (parallel, crossover, factorial, etc.)
  - Participants: Eligibility criteria, settings, locations
  - Interventions: Precise details of interventions for each group
  - Outcomes: Primary and secondary, how and when assessed
  - Sample size: Calculation with assumptions stated
  - Randomization: Sequence generation, allocation concealment
  - Blinding: Who was blinded, how blinding was maintained

Results:
  - CONSORT flow diagram (enrollment, allocation, follow-up, analysis)
  - Baseline demographic table (Table 1)
  - Primary outcome with effect size and confidence interval
  - Harms and adverse events

Discussion:
  - Limitations including sources of potential bias
  - Generalizability
  - Interpretation consistent with results
```

## STROBE for Observational Studies

### Key STROBE Requirements

```
Study design specific items:

Cohort:
  - Report follow-up time (person-years, median)
  - Report loss to follow-up with reasons
  - Use hazard ratios or incidence rate ratios

Case-Control:
  - Describe case definition and case ascertainment
  - Describe control selection (source, matching criteria)
  - Report odds ratios with confidence intervals

Cross-Sectional:
  - Report response rate and non-response analysis
  - Describe how the sample represents the target population
  - Report prevalence with confidence intervals
```
