# Peer Review Standards for Clinical Manuscripts
Peer review ensures that clinical manuscripts meet standards for scientific rigor, ethical conduct, and clear communication before publication.

## Overview

# Peer Review Standards for Clinical Manuscripts

## Overview of Clinical Manuscript Peer Review

### Purpose

Peer review ensures that clinical manuscripts meet standards for scientific rigor, ethical conduct, and clear communication before publication.

**Objectives:**
- Assess scientific validity and methodology
- Evaluate clinical significance
- Verify ethical compliance
- Ensure clarity and completeness
- Improve manuscript quality

**Types of peer review:**
- Single-blind (reviewer knows author, author doesn't know reviewer)
- Double-blind (both parties anonymous)
- Open peer review (both parties known)
- Post-publication peer review

### Reviewer Responsibilities

**Accept reviews only when:**
- Qualified in the subject area
- No conflicts of interest
- Adequate time available (typically 2-3 weeks)
- Can provide constructive, unbiased evaluation

**Maintain confidentiality:**
- Do not share manuscript content
- Do not use information for personal advantage
- Do not involve others without editor permission

**Provide timely review:**
- Complete within requested timeframe
- Notify editor promptly if unable to complete

## Case Report Review Criteria

### CARE Guideline Compliance

**Verify manuscript includes:**
- [ ] Title identifies it as case report
- [ ] Keywords provided (2-5)
- [ ] Structured or unstructured abstract
- [ ] Introduction explaining why case is novel

- [ ] Clinical findings
- [ ] Timeline of events
- [ ] Diagnostic assessment
- [ ] Therapeutic interventions
- [ ] Follow-up and outcomes

### Novelty and Significance

**Assess:**
