There shouldn’t have been many differences between the women recruited for the three clinical trials: All of them gave birth at the same two Cairo hospitals over a period of less than three years, and all of them were treated to prevent or manage postpartum bleeding. Three samples from this pool of patients, Ben Mol felt, should have had largely similar baseline characteristics.
Yet, mysteriously, the women’s mean age and BMI varied markedly across the studies—from 25 to 34 years and from 25 to 29 kg/m2, respectively—as did the birthweight of their babies.
