FIG. 1

Description of transitions from baseline panty groups into the interim birth groups during follow-up. Figure shows possible sequences of joint parity and GDM status (ignoring which exam transition). In terms of sequential states, the only allowable transitions are from state 1 to state 2 and from state 2 to state 3. State 1 is always at baseline, states 2 and 3 always during follow-up. Each transition can occur at any examination, except that GDM is an absorbing state (always henceforth classified as GDM after first having had it, even though a subsequent birth might be free of GDM) and nulliparous or no interim birth does not allow GDM.
