Abstract

SVD = spontaneous vaginal deliveries; IVD = instrumental vaginal deliveries; CS = cesarean sections. https://doi.org/10.1371/journal.pone.0213664.g001 There is an error in the caption for Fig 2. Conceptual framework explaining the relationship between various determinants and length of hospital stay after childbirth (LoS). https://doi.org/10.1371/journal.pone.0213664.g002 There is an error in Table 2. Table 2 displays the classes of clinical explanatory factors related with the maternal health domain: mother’s age, hypertension/diabetes, amniocentesis, villi sample, fetoscopy, pre-delivery LoS, presentation, labour induction, labour analgesia, neonatal status, number of obstetric checks performed, number of ultrasound (US) scans performed. 1.

Table 5. Multiple logistic regression analysis.

Outcome: length of hospital stay (LoS) longer than ED benchmarks (2 days for spontaneous vaginal deliveries; 3 days for instrumental vaginal deliveries). Effect estimates for hospital and calendar year adjusted for all other factors. Adjusted odds ratios (aOR*) and population attributable risks (PAR1$, PAR2,** PAR3,$ PAR4**) with 95% confidence intervals (95%CI). NA = Not available; observations = complete (case analysis) observations.

In the Results, there is an error in the second sentence of the penultimate paragraph. The correct sentence is: The proportional increase in LoS<ED for SVD would range from +23.1% (centre J) up to +64.5% (centre B), and would be +59.0%, +49.7%, +49.5%, +46.7%, +37.5%, +27.4% and +26.3% for centres D, I, K, E, C, F and H respectively (PAR1).

In the Generalizability subsection of the Discussion, there is an error in the first sentence of the first paragraph. The correct sentence is: The pooled mean LoS for SVD was 2.9 days in FVG during the whole study period (2005–2015), shorter than the average figures most recently reported for the whole of Italy (3.4 days).

There are errors in the Methods.

The title of the subsection “Child’s clinical factors fragility” is incorrect. The correct subsection title is: “Child’s clinical factors.”

In the Statistical analysis subsection, there is an error in the third item of the first list. The correct third item is: previous spontaneous abortions, as the relative effect size was not consistent across the two vaginal delivery modes.

In the Maternal health factors subsection, there is an error in the first sentence of the first paragraph. The correct sentence is: Table 2 displays the classes of clinical explanatory factors related with the maternal health domain: mother’s age, hypertension/diabetes, amniocentesis, villi sample, fetoscopy, pre-delivery LoS, presentation, labour induction, labour analgesia, neonatal status, number of obstetric checks performed, number of ultrasound (US) scans performed.
