The analgesic efficacy of paravertebral block for percutaneous nephrolithotomy: A meta-analysis of randomized controlled studies.
Synthesis in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
introductionThe analgesic efficacy of paravertebral block for percutaneous nephrolithotomy remains controversial. We conduct a systematic review and meta-analysis to explore the analgesic efficacy of paravertebral block for patients with percutaneous nephrolithotomy.
methodsWe have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases, and randomized controlled trials (RCTs) assessing analgesic efficacy of paravertebral block for percutaneous nephrolithotomy are included in this meta-analysis.
resultsFive RCTs are included in the meta-analysis. Overall, compared with control group after percutaneous nephrolithotomy, paravertebral block is associated with the decrease in analgesic consumption (standard mean difference (Std. MD) = -1.55; 95% confidence interval (CI) = -2.18 to -0.92; P < .00001) and additional analgesics (risk ratio (RR) = 0.17; 95% CI = 0.07 to 0.44; P = .0003), prolonged time to first analgesic requirement (Std. MD = 1.51; 95% CI = 0.26 to 2.76; P = .02). There is no statistical difference of adverse events including nausea or vomiting (RR = 0.51; 95% CI = 0.11 to 2.35; P = .38), or itching (RR = 0.69; 95% CI = 0.26 to 1.81; P = .45) between 2 groups.
conclusionsParavertebral block is effective for pain control after percutaneous nephrolithotomy.
