KONSİLResearch guides
How to do by hand what KONSİL automates. Every guide rests on primary sources and the standards the field already accepts; useful whether or not you use the product.
Need a number? Sample size calculators by design — free, no sign-up, deterministic.
What is ORCID and how to register
A five-step registration walkthrough with screenshots, a visibility-settings table, and answers to the duplicate-iD and changing-institution questions.
Does a retrospective study need ethics approval?
Short answer: yes. A decision-tree diagram, the three conditions of a consent waiver, and what boards specifically ask of retrospective applications.
How to prepare an ethics committee (IRB) application
Which study goes to which committee, the 17 sections every file needs in one table, how to justify sample size, a consent checklist, and the most common rejection reasons.
How to choose a target journal
Reading quartiles correctly, an APC comparison table, a predatory-journal checklist, national platforms like DergiPark, and the 8 most common desk-rejection reasons with fixes.
How to find research collaborators outside your institution
Define the role before the person, assess candidates by their output in your topic rather than their overall h-index, write a first email that gets a reply, and read the red flags early.
Has my research idea already been studied?
The better question is which part is already done. Split the idea into four components, search registries and repositories as well as journals, and stop treating an empty result set as evidence.
How to identify a defensible research gap
Absence is not a gap. Five kinds of gap, where each is found, four false gaps that waste a project, and a three-sentence gap statement a reviewer will accept.
How to set up a multi-site research study
The hard part is administrative, not scientific: site selection, a protocol another team can run without asking, ethics sequencing, a shared data dictionary, and an authorship rule agreed before the first participant.
Effect size: the number your sample size is hostage to
d, dz and f in plain language; a computed smooth curve showing n rising continuously as the effect shrinks; four defensible sources for your own number.
From textbook n to real-world n: dropout, multiplicity, ANCOVA
One coherent example: base n = 128 falls to 84 analyzable participants with ANCOVA at r = 0.60, then 20% expected attrition sets the recruitment target at 105.
Sample size for diagnostic accuracy studies
Most accuracy studies need a precision-based sample size, not a power calculation. Sizing sensitivity and specificity, the prevalence step that actually drives feasibility, McNemar's discordant-pair trap and verification bias — with worked numbers.
CRediT: how to write an author contribution statement
Author order says nothing; CRediT does. What each of the 14 roles actually means, a worked statement, how it differs from ICMJE authorship criteria, and the five mistakes reviewers notice.
The system that does this for you
KONSİL tests your idea against open scholarly data, writes the defensible gap, derives the roles the study requires and lists researchers you can actually reach for each one. We published a full sample report.
