A Comparative Study of Fractionated Versus Single Dose Injection for Spinal Anesthesia During Cesarean Section in Patients with Pregnancy-Induced Hypertension.
Article in Anesthesiology and pain medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 8 papers.
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.

Abstract
backgroundLocal anesthetics for spinal anesthesia in one-single injection are known to induce more severe hypotension than a fractionated dose in healthy obstetric patients. Hypotension in obstetric patients with pregnancy-induced hypertension, including preeclampsia, during spinal anesthesia, could compromise fetal well-being.
objectivesThis study aimed to compare the mean arterial pressure (MAP), the total dose of ephedrine required, and level of sensory blockade between the fractionated-dose and single-dose spinal anesthesia injection in obstetric patients with pregnancy-induced hypertension who underwent a cesarean section.
methodsThis single-blind randomized clinical trial was conducted from January to April 2018 after being approved by the Research Ethics Committee of Universitas Indonesia (No. 1174/UN2.F1/ETIK/2017) and recorded at ClinicalTrials.gov (NCT03693638). After obtaining informed consent, 42 parturients with hypertension in pregnancy (gestational hypertension or preeclampsia), ASA II-III, aged 18 - 40 years, and BMI of 18.5 - 35 kg/m
resultsThere was no significant difference between the two groups in MAP in the first 15 minutes after anesthesia (P > 0.05) and median total dose of ephedrine required (10 (0 - 25) mg in the FD group vs. 15 (0 - 30) mg in the SD group, P = 0.30). However, in the FD group, MAP tended to be higher in the first three minutes compared to the SD group. The level of sensory blockade was mostly at T4, which was not significantly different between the groups (52.4% in FD vs. 42.9% in SD, P = 0.59).
conclusionsIn obstetric patients with pregnancy-induced hypertension who underwent a cesarean section, the mean arterial pressure after spinal anesthesia was not significantly different between the fractionated dose of spinal anesthesia injection and single-dose injection. Total ephedrine required and levels of sensory blockade were not significantly different between the groups.
