Antepartum tracings were performed in the 48 h that preceded an elective cesarean section, and intrapartum tracings were performed until delivery. FHR baselines were estimated by an expert, according to an objective and reproducible methodology. Using these baselines, automated detection of accelerations and decelerations and estimation of variability was performed by the personal computer. A quantitative adaptation of the FIGO guidelines for fetal monitoring was used to classify tracings. Perinatal outcome was classified according to the Apgar score and umbilical arterial pH. Validity was then assessed by the proportions of agreement (PA), kappa statistic (\u03ba), sensitivity and specificity, with 95% confidence intervals (95% CI). Cases showing a disagreement between CTG and perinatal classification were reviewed and an adjustment in baseline definition was tested. <jats:italic>Results<\/jats:italic>: The initial overall PA and \u03ba between CTG and perinatal classification were, respectively, 0.79 (95% CI: 0.69\u20130.87) and 0.62 (95% CI: 0.41\u20130.83). The overall PA and \u03ba, after baseline adjustment were, respectively, 0.89 (95% CI: 0.81\u20130.95) and 0.78 (95% CI: 0.58\u20130.98). Sensitivities and specificities ranged between 79% (95% CI: 60\u201392%) and 100% (95% CI: 95\u2013100%). <jats:italic>Conclusions<\/jats:italic>: Good clinical prediction may be possible with an objective methodology for cardiotocogram analysis based on a recently described reproducible baseline estimation.<\/jats:p><\/jats:sec>","DOI":"10.1016\/s0020-7292(98)00079-4","type":"journal-article","created":{"date-parts":[[2002,7,25]],"date-time":"2002-07-25T18:31:15Z","timestamp":1027621875000},"page":"141-147","source":"Crossref","is-referenced-by-count":45,"title":["Objective computerized fetal heart rate analysis"],"prefix":"10.1002","volume":"62","author":[{"given":"J","family":"Bernardes","sequence":"first","affiliation":[]},{"given":"D","family":"Ayres\u2010de\u2010Campos","sequence":"additional","affiliation":[]},{"given":"A","family":"Costa\u2010Pereira","sequence":"additional","affiliation":[]},{"given":"L","family":"Pereira\u2010Leite","sequence":"additional","affiliation":[]},{"given":"A","family":"Garrido","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[1998,8,6]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7292(97)02846-4"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1996.tb09844.x"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1515\/jpme.1984.12.5.227"},{"key":"e_1_2_6_5_2","unstructured":"Bernardes J Moura C Marques\u2010de\u2010S\u00e1 JP Pereira\u2010Leite L van Geijn HP.
