This skill provides specialized guidance for the writing characteristics of papers in medicine, biology, and clinical research.
I. Characteristics of Medical Papers
Differences from Other Disciplines
| Aspect | Medical Papers | General Science and Engineering |
|---|---|---|
| Structure | Strict IMRAD + reporting guidelines | IMRAD |
| Ethics | Ethics approval must be stated | As the case may be |
| Statistics | Detailed statistical methods required | Basic statistics |
| Reporting | Specific reporting guidelines must be followed | No mandatory requirement |
| Registration | Clinical trials require preregistration | No requirement |
Common Types of Medical Papers
- Randomized controlled trial (RCT): drug/treatment efficacy evaluation
- Cohort study: long-term follow-up observation
- Case-control study: retrospective analysis
- Cross-sectional study: survey at a certain time point
- Systematic review/Meta-analysis: comprehensive analysis of literature
- Case report: description of rare cases
II. Reporting Guidelines
| Study Type | Reporting Guideline | Core Requirements |
|---|---|---|
| Randomized controlled trial | CONSORT | Flow diagram, randomization method, blinding, ITT analysis |
| Observational study | STROBE | Study design, participants, variables, bias |
| Systematic review | PRISMA | Search strategy, screening process, quality assessment |
| Diagnostic accuracy | STARD | Reference standard, blinding, 2×2 table |
| Case report | CARE | Timeline, diagnostic reasoning, follow-up |
| Animal study | ARRIVE | Sample size, randomization, blinding |
III. Medical Writing Standards
Ethics Statement
Required content:
本研究经[医院名称]伦理委员会批准(批准号:XXX-XXX-XXX),
所有参与者均签署知情同意书。本研究遵循《赫尔辛基宣言》原则。
Clinical trial registration:
本试验已在中国临床试验注册中心注册(注册号:ChiCTR-XXX-XXXXXXXX)。
Description of Statistical Methods
Standard template:
统计分析使用SPSS 26.0(IBM Corp., Armonk, NY, USA)进行。
计量资料以均数±标准差(x̄±s)表示,组间比较采用独立样本t检验;
计数资料以例数(百分比)表示,组间比较采用χ²检验。
P<0.05为差异有统计学意义。
Results Reporting Format
Continuous variables:
- Normal distribution: mean ± standard deviation, e.g.,
45.3±12.7岁 - Non-normal distribution: median (interquartile range), e.g.,
23.5(15.2-38.7)
Categorical variables:
- Number of cases (percentage), e.g.,
156例(62.4%)
Statistical test results:
- t-test:
t=2.45, P=0.016 - Chi-square test:
χ²=8.32, P=0.004 - Regression analysis:
OR=2.35, 95%CI: 1.42-3.89, P=0.001
Table Standards
Example of a baseline characteristics table:
| Characteristic | Trial group (n=50) | Control group (n=50) | P value |
|---|---|---|---|
| Age (years) | 45.3±12.7 | 44.8±11.9 | 0.842 |
| Male, n(%) | 28(56.0) | 25(50.0) | 0.548 |
| BMI(kg/m²) | 24.2±3.1 | 23.8±2.9 | 0.498 |
IV. Medical Terminology Standards
P Value Reporting
- P<0.001: write directly as
P<0.001 - 0.001≤P<0.05: write the exact value, e.g.,
P=0.023 - P≥0.05: write the exact value, e.g.,
P=0.156 - Avoid writing
P=0.000, should writeP<0.001
Number Standards
- Keep a consistent number of decimal places
- Percentages retain 1 decimal place
- P values retain 3 decimal places
- Confidence intervals retain 2 decimal places
V. Medical Paper Checklist
Ethics and Registration
