“Material and Methods”

Under the heading “Randomization and blinding” the sentence should read in full: Concealment was achieved using opaque envelopes, to blind the pysicians, while to blind the patients, the placebo tablet was methylcellulose resembling letrozole in shape.

“Results”

In the 1st paragraph, the last sentence correctly reads: There were no significant differences in age and gestational age between the two groups ([Table 1]).

Under the heading “Comparison of gravidity”, the p-value has been corrected in the last sentence of the 1st paragraph. Correct is: p = 0.742.

Under the heading “Comparison of previous cesarean sections”, the p-value has been corrected in the penultimate sentence. Correct is: p = 0.117.

[Table 1] has been corrected. Correct is:

Yes (incomplete miscarriage)	134	61	48	22

[Table 3] has been corrected. Correct is:

Table 3 Comparison of onset and duration of vaginal bleeding and onset of passing products of conception (clinical data).

Clinical findings	Group 1 (placebo)	Group 2 (letrozole)	p-value
Time to 1st vaginal bleeding after administration of misoprostol, days			< 0.001
