Built to satisfy the most demanding peer reviewers and editorial boards.

Systematic Review

Three months left in fellowship and a meta-analysis I had barely started. The team picked up the pooled analysis on heart failure outcomes, redrew every forest plot, and reran a leave-one-out sensitivity check I had not thought of. Submission went through with two rounds of revisions, both manageable. The reproducibility pack saved me real time when reviewers pushed back on the heterogeneity choices.

Scoping review on malaria chemoprevention attached to a foundation grant. Their librarian rebuilt the search across five databases, handled PROSPERO drafting, and dual-screened roughly 2,300 records. Turnaround on the protocol stage was slower than I expected, but they were upfront about it and the actual review landed on time. Would use them again for the next phase.
Dr. R. Okonkwo
Public Health Researcher

I came in with extracted data from 27 breast cancer trials and no statistician. They reconstructed the analysis in R, ran the network meta-analysis with SUCRA rankings, and built the GRADE Summary of Findings table I could not have written myself. The R scripts ran on my laptop without modification, which is rare.
Dr. M. Al-Rashidi

Umbrella review on cardiovascular outcomes after bariatric surgery. Deliverable arrived with full reproducibility files, AMSTAR-2 ratings on every included review, and a clean overlap matrix. My junior faculty could actually defend the methods section in seminar. Worth what we paid.
Prof. L. Henrik

Denmark
Network meta-analysis on neonatal sepsis treatment, fourteen antibiotics, eight outcomes. I would not have known where to start. Scope shifted twice on my side and they re-quoted both times without drama. Final network ranked the interventions cleanly and the sensitivity analyses held up under reviewer scrutiny.
Dr. A. Patel

Systematic review of CBT for treatment-resistant depression, tied to a federal grant resubmission. They delivered the protocol, full search log, dual screening, and a clean narrative synthesis in seven weeks. The resubmission was funded on the next cycle. Money well spent.
Dr. K. Tanaka
Clinical Psychiatrist
Japan
Antibiotic resistance surveillance review across six databases and four languages. Their information specialist ran translated search strings I could never have built alone, then documented every filter and limit for the PRISMA flow. The reproducibility pack alone saved me a week.
