meta-analysis

meta-analysis is a skill for Claude Code, Codex from zamushwani/biomedical-ai-skills. It costs 0 tokens per session (12,808 once invoked), scanned A, original, MIT.

A workflow for systematic reviews and meta-analyses, which combine evidence from multiple clinical or preclinical studies. It covers finding studies, screening them, judging their reliability, and statistically combining their results.

In plain words
What is it for?
Use it to write review protocols, search PubMed, Embase, or Cochrane CENTRAL, remove duplicate records, manage screening, calculate effect sizes, pool results, assess differences between studies, and rate certainty.
Why use it?
It organizes review decisions and makes differences between studies, possible bias, and uncertainty visible. This reduces the risk of drawing conclusions from incomplete or incomparable evidence.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

meta-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Meta-Analysis

Systematic review and meta-analysis for clinical and preclinical evidence. Covers protocol registration, search strategy, screening, PRISMA 2020 flow diagrams, risk of bias, pooling with fixed and random effects models, small-study effects, sensitivity diagnostics, network meta-analysis, and GRADE/CINeMA certainty rating. Uses metafor, netmeta, PRISMA2020, synthesisr, and robvis.

When to Use This Skill

Activate when the user requests:

  • A systematic review or meta-analysis protocol
  • Search strategy construction for PubMed, Embase, or Cochrane CENTRAL
  • PRISMA 2020 flow diagram generation
  • Deduplication of records across databases
  • Title/abstract or full-text screening workflows
  • Inter-rater agreement between screeners
  • Risk of bias assessment (RoB 2, ROBINS-I, ROBINS-E, QUADAS-2, Newcastle-Ottawa)
  • Risk of bias visualization (traffic light or summary plots)
  • Data extraction templates for RCTs or observational studies
  • Effect size computation (OR, RR, RD, SMD, MD, ROM, HR)
  • Pooling with equal-effects or random-effects models
  • Heterogeneity quantification (tau^2, I^2, Q) and prediction intervals
  • Subgroup analysis and meta-regression
  • Hazard ratio reconstruction from published Kaplan-Meier curves
  • Forest and funnel plots
  • Publication bias or small-study effect assessment
  • Leave-one-out, influence, or cumulative sensitivity analysis
  • Network meta-analysis, transitivity, inconsistency, or treatment ranking
  • GRADE or CINeMA certainty rating

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
