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
BACKGROUND Pregnancy-related anatomical and physiological changes, such as mucosal edema and increased oxygen demand, heighten risk of difficult airway, especially under general anesthesia. This study compared effects of spinal and general anesthesia on postoperative airway assessment tests in cesarean deliveries. We hypothesized upper airway changes can occur depending on anesthesia technique. MATERIAL AND METHODS This prospective observational study included 100 pregnant women undergoing elective cesarean delivery. Patients were divided into 2 groups according to anesthesia type: spinal (n=64) and general (n=36). Five basic airway assessment tests (modified Mallampati score, thyromental distance, sternomental distance, neck circumference, and upper lip bite test) were performed preoperatively and 1, 6, and 24 h after surgery (T1-T4). RESULTS No significant changes were observed over time in the spinal group (all P>0.05), with Mallampati scores remaining stable from T1 to T4 (mean T1: 1.7±0.6; T4: 1.8±0.5). In contrast, general anesthesia group showed a significant increase in Mallampati scores at T2 (T1: 1.7±0.6 vs T2: 2.4±0.7, P<0.001). Postoperative nausea and vomiting were more frequent in the general anesthesia group (27.8% vs 10.9%, P=0.016). In hemodynamic evaluation, systolic and diastolic blood pressure values were significantly higher at the 2nd and 5th minutes in the general anesthesia group (2nd min SBP: 128.4±20.6 mmHg vs 114.5±17.4 mmHg; 5th min SBP: 121.4±15.6 mmHg vs 107.1±14.7 mmHg; both P<0.001). CONCLUSIONS The significant increase in Mallampati scores after general anesthesia highlights the potential for upper airway edema due to intubation. Anticipating this risk is important for airway safety in the early postpartum period.
