Which way is better to deliver the very heavy baby: mode of delivery, maternal and neonatal outcome.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeCurrently there are no existing data regarding the maternal and neonatal outcomes for nulliparous women delivering neonates with birthweight above 4500 g. We aim to evaluate birth outcome among these subset of parturients.
methodsA retrospective study of nulliparous delivering a singleton fetus weighing ≥ 4500 g in two tertiary medical centers between 2007 and 2018. Women who chose to undergo a trial of labor (TOL) were compared to those who underwent elective cesarean delivery (CD).
resultsOverall, 121 women were included. Seventy eight (65.4%) women elected a TOL while 43 (34.6%) had elective CD. Of women who chose TOL, 46 (59%) delivered with unassisted vaginal delivery, 28 (36%) by intrapartum CD, and 4 (5%) by assisted vaginal delivery, reaching TOL success rate of 64% (50/78). The rates of shoulder dystocia and anal sphincter injury in vaginal deliveries were 5/50 (10%) and 2/50 (4%) respectively. Successful TOL was negatively associated with the presence of gestational diabetes [5 (18%) vs. 0 (0%), OR 0.8 (95% CI 0.7-0.9), p = 0.005], and was positively associated with maternal height (median 170 cm vs. 165 cm, p = 0.002), epidural analgesia [42 (84%) vs. 16 (57%), OR 3.5 (95% CI 1.2-9.8), p = 0.009] and spontaneous onset of labor (38 (76%) vs. 10 (36%), OR 5.7 (95% CI 2.1-15.6), p = 0.001. Neonates born after TOL were more commonly complicated by meconium aspiration syndrome as compared to no TOL (9 (11%) vs. 0 (0%), OR 1.1 (95% CI 1.04-1.22, p = 0.02). Only maternal height was independently associated with successful TOL (aOR 6.9 (95% CI 1.03-46.3, p = 0.04). Maternal and neonatal adverse composite outcomes were associated with gestational hypertensive disorders (10 (50%) vs. 5 (5%). OR 19.2 (5.5-67.4), p < 0.001) and with delivery before 40 weeks (9 (57%) vs, 86 (82%), OR 3.5 (95% CI 1.2-10.6, p = 0.02), respectively.
conclusionsTrial of vaginal delivery in nulliparous with fetuses ≥ 4500 g was associated with a high failure rate, with only two thirds of parturients achieving successful vaginal delivery. Nevertheless, neonatal outcomes mostly did not differ according to the mode of delivery. Maternal height was the only factor associated with successful vaginal delivery.
