Accrual curve
A cumulative enrolment trace draws itself up towards a fixed target rule, the leading point tracking along the curve as it grows.

15 animationsAllocation ratio
One enrolment track is divided between two abutting arm segments that trade width across the divider, the pair always filling the track exactly.
CSSBlinding
A kit label carrying a readable treatment code slides under a masking panel until only the blinded kit number remains showing.
CSSCode break
A sealed code envelope has its seal band split and its flap lift, and the arm assignment inside rises into view before the seal reforms.
CSSCrossover design
Two sequence lanes run left to right, cross at a washout window in the middle and swap sides, each carrying a dash train that shifts by exactly one period per cycle.
CSSDose escalation
A dose ladder climbs rung by rung as a cohort of three subject dots fills the rung it is on, then the cohort clears and reforms one rung higher.
CSSEndpoint estimate
A forest-plot row shows a confidence interval whisker contracting about its point estimate until the whole interval clears the null line and the point locks.
CSSInterim boundary
A test statistic walks look by look between two converging stopping boundaries and crosses the upper one at the final analysis.
CSSPhase progression
Four phase bands of increasing cohort width sit on one rule and the programme marker steps from band to band, each band it leaves staying filled behind it.
CSSRandomisation
Subject tokens drop down a central chute into a splitter and are deflected alternately into the treatment and control bins below it.
CSSRetention
A cohort gauge ring fills to the full enrolled count and then gives back the withdrawals, resting on the fraction still on study.
CSSScreening funnel
A screening front sweeps down a funnel with the screen failures turned out at the walls, the narrow neck carrying the accepted fraction to the subject released below.
CSSSite activation
Three investigator site branches feed a coordinating node and a single enrolment trunk, each branch running its arrivals a third of a period out of step with the next.
CSSSurvival curve
A time cursor sweeps a Kaplan-Meier step curve and the survival readout on the axis drops each time the knot riding the curve passes an event.
CSSVisit window
A study-day rule of repeating protocol visit windows scrolls past a fixed actual-visit index, which dims whenever it falls between two windows.
