Importing

Set the review up to succeed

Define your question and context, then import references from any database or reference manager. Duplicates are removed automatically, before anyone screens a single title.

Screening

Screen faster without compromise

Independent dual screening, blinding and structured conflict resolution come as standard. Surfaces likely includes earlier, and every decision stays yours and stays recorded.

At full text, exclusion reasons are captured as you work, so your PRISMA numbers and your audit trail build themselves. Reviewers see progress at a glance, and supervisors can see where a review is stuck.

#6 - Maggini 2012

A combination of high-dose vitamin C plus zinc for the common cold.

Vitamin C and zinc play important roles in nutrition, immune defence and maintenance of health. Intake of both is often inadequate, even in affluent populations. The common cold continues to place a great burden on society in terms of suffering and economic loss. After an overview of the literature on the effects of the separate administration of either vitamin C or zinc against the common cold, this article presents data from two preliminary, double-blind, randomized, placebo-controlled trials, conducted with a combination of 1000 mg vitamin C plus 10 mg zinc in patients with the common cold.

Data extraction

Spend less time extracting, more time thinking

Build extraction templates once and reuse them across the team. Suggestions point you to the supporting text in the source, so you verify rather than retype — and you confirm every value that lands in your dataset.
