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 Spinal anesthesia-induced hypotension is a frequent and critical problem during cesarean section, carrying risks for both mother and fetus. Prophylactic vasopressors and mechanical manipulation of the uterus are common preventative methods. The primary aim of this study was to assess the effectiveness of prophylactic phenylephrine bolus versus 15° left lateral tilt in preventing maternal hypotension. Material and methods In this randomized comparative study, 144 women who were planned to undergo elective cesarean delivery under spinal anesthesia were divided into two groups. Group A (n=72) was given a prophylactic intravenous bolus of 100 mcg of phenylephrine immediately after spinal injection. In group B (n=72), patients were placed in a 15° left lateral tilt with an obstetric wedge. The only outcome was the occurrence of hypotension (systolic pressure 20% decrease from baseline). Results Hypotension occurred in 65.3% (n=47) of patients in the phenylephrine group and 54.2% (n=39) of patients in the left tilt group. The difference between these groups was not statistically significant (p=0.159). Patients with a BMI over 30 kg/m² showed a higher incidence of hypotension after spinal anesthesia. However, there was no statistically significant difference in hypotension rates between those receiving phenylephrine and those positioned in a 15° left lateral tilt within this subgroup. Similarly, low baseline systolic blood pressure (SBP; 100-120 mmHg) was also a significant predictor of hypotension in both groups. Conclusion There was no benefit of phenylephrine 100 mcg bolus over a 15° tilt in the prevention of spinal anesthesia-induced hypotension for elective cesarean delivery. Both methods are popular options, but they may not be enough as individual prophylactic measures, and this might indicate the necessity of combination or more aggressive therapy.
