The impact of body mass index on the risk of high spinal block in parturients undergoing cesarean delivery: a retrospective cohort study.
Article in Journal of anesthesia, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06060015 (Effect of Subarachnoid Hyperbaric Bupivacaine on Mean Arterial Pressure in Obese Pregnant Patients Undergoing Cesarean Section), which is not on this map. Cited by 17 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

Abstract
purposeTo investigate the hypothesis that the risk of high spinal block is not increased in obese parturients undergoing cesarean delivery compared to non-obese parturients.
methodsThis is a retrospective study at an academic center. We searched the perioperative database for women who underwent cesarean delivery under spinal or combined spinal epidural anesthesia with hyperbaric bupivacaine ≥10.5 mg. A body mass index (BMI) ≥30 kg/m
resultsThe analysis included 5015 women. High spinal blocks occurred in 29 patients (0.6%). The risk of high spinal was significantly different according to BMI (p = 0.025). In a multivariate model, BMI (p = 0.008) and cesarean delivery priority (p = 0.009) were associated with high blocks. BMI ≥50 kg/m
conclusionsAt standard spinal doses of hyperbaric bupivacaine used in our practice (≥10.5 mg), there were greater odds of high block in those with BMI ≥50 kg/m
