“…Of the 12 studies with positive results (Table ), four studied adult females only [Norton et al, ; Jha et al, ; Arunkalaivanan et al, ; Lammers et al, ], five adult males and females [Pulliam and Schuster, ; Al‐Rawi et al, ; Reilly et al, ; Vounotrypidis et al, ; Zarate et al, ], two children and adolescents from both sexes [Mohammed et al, ; Kajbafzadeh et al, ], and one children, adolescents and adults from both sexes [Marshman et al, ]. These works differed also for the assessing method for gJHM, which was the Beighton score with a positive cut‐off of >4 four times [Jha et al, ; Reilly et al, ; Arunkalaivanan et al, ; Zarate et al, ], Beighton score with a positive cut‐off of ≥4 twice [Al‐Rawi et al, ; Kajbafzadeh et al, ], Beighton score with an undefined positive cut‐off once [Vounotrypidis et al, ], the self‐reported 5‐point questionnaire once [Mohammed et al, ], and a self‐developed screening method four times [Marshman et al, ; Norton et al, ; Pulliam and Schuster, ; Lammers et al, ]. Association between gJHM and chronic constipation, alternatively termed as chronic intestinal pseudoobstruction [Pulliam and Schuster, ] or slow transit constipation [Mohammed et al, ], appeared the most consistent, being observed four times in both sexes from all ages [Pulliam and Schuster, ; Reilly et al, ; Mohammed et al, ; Kajbafzadeh et al, ].…”
