Thoracic paravertebral regional anesthesia for pain relief in patients with breast cancer surgery.

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
backgroundThe present study aimed to assess the efficacy and safety of thoracic paravertebral regional anesthesia (TPVBRA) in patients with breast cancer surgery.
methodsIn total, 72 patients undergoing breast cancer surgery were randomly divided into an intervention group and a control group; each group contained 36 subjects. Both groups received TPVBRA with 20 mL 0.25% bupivacaine. In addition, subjects in the intervention group also received an additional 1 μg/kg dexmedetomidine. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), pain intensity (measured by visual analogue scale, VAS), and analgesic consumption were assessed; adverse events were also recorded.
resultsSignificant differences were observed in HR (P < .05), SBP (P < .05), and DBP (P < .05) at the 30-minute point during surgery between the 2 groups. In addition, the time of the first administration of analgesia (P = .043) and the mean consumption of analgesic agents (P = .035) in the intervention group were much better than those in the control group. However, no significant differences in HR or VAS were found at any time point after surgery (P > .05). Furthermore, similar adverse events were detected in both groups (P > .05).
conclusionThe results of this study showed that TPVBRA combined with bupivacaine and dexmedetomidine can enhance the duration and quality of analgesia without serious adverse events.
