Burns E, Feeley C, Hall PJ, et al. Systematic review and meta-analysis to examine intrapartum interventions, and maternal and neonatal outcomes following immersion in water during labour and waterbirth. BMJ Open 2022;12:e056517. doi: 10.1136/bmjopen-2021-056517.
The authors want to alert the readers to the below errors in table 2 and reference 47:
In table 2, an error was noted for maternal parity in column 1 ‘Excludes Multiparous’ where all but three of the ‘Yes’ entries were incorrectly reported. These have been amended to ‘No’ to indicate the studies that included nullipara and multipara. Additional maternal parity- related amendments include a change from ‘no’ to ‘yes’ for Liu46 which only included nullipara, like-wise for Theoni59, and from ‘no’ to n.d. for Ziolkowski65. (not described - see table footnote)
There is also an error in the reference list. Reference 47 is incomplete and a duplicate of reference 48. The full reference is: Mallen-Perez L, Roé-Justiniano MT, Colomé Ochoa N, et al. Use of hydrotherapy during labour: Assessment of pain, use of analgesia and neonatal safety. Enferm Clin (Engl Ed). 2018 Sep-Oct;28(5):309-315. PMID:http://www.ncbi.nlm.nih.gov/pubmed/29239794.
