cumulative-tracking

name	cumulative-tracking
description	Track evidence accumulation over time — cumulative meta-analysis protocol design. Budget: 40 studies, 40 effect sizes, 30 web searches.

Cumulative Tracking Strategy

Design a cumulative meta-analysis protocol tracking how evidence evolves over time as new studies are published.

Purpose

Cumulative meta-analysis adds studies one-by-one in chronological order, showing when the evidence became conclusive, whether early studies were misleading, and how the pooled estimate stabilized. This strategy produces the protocol for temporal evidence tracking.

Budget

Resource	Floor	Target
Studies identified	28	40
Effect sizes extracted	28	40
Web searches	20	30
Temporal coverage (years)	5	10+
Quality assessments	20	40

Budget gate: cannot exit until 80% of floor met.

Available Tactics

Tactic	When to Use
effect-size-extraction	Extract effect sizes with publication dates
quality-assessment-protocol	Assess quality evolution over time
evidence-synthesis-planning	Plan cumulative pooling approach

Available SOPs

SOP	When to Use
pico-formulation	Frame the temporal evidence question
inclusion-criteria-design	Define eligibility with temporal scope
effect-size-planning	Standardize effect sizes for temporal pooling
data-extraction-form	Template with mandatory date fields
risk-of-bias-assessment	Per-study assessment (track quality trends)
heterogeneity-source-analysis	Time-varying heterogeneity
sensitivity-analysis-design	First-study effect, vintage analysis
publication-bias-assessment	Time-lag bias assessment
meta-analysis-synthesis	Final cumulative protocol assembly

Execution Guidance

1. Frame — Run pico-formulation with temporal dimension explicit
2. Scope — Run inclusion-criteria-design with date range requirements
3. Search — Systematic search emphasizing complete temporal coverage
4. Order — Sort studies chronologically by publication date
5. Extract — Use effect-size-extraction tactic with date metadata
6. Assess — Use quality-assessment-protocol noting temporal trends
7. Plan — Use evidence-synthesis-planning for cumulative model
8. Synthesize — Run meta-analysis-synthesis for final protocol

Ensure no temporal gaps. Flag periods with no publications.
