Short-term results of intrathecal injection of low-dose bupivacaine in outpatients with chronic low back and lower extremity pain.
Trial report in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate the safety and efficacy of intrathecal injection as an alternative to epidural injection for analgesia.
methodsSeventy consecutive outpatients with chronic low back and lower extremity pain received lumbar intrathecal injection of low-dose isobaric bupivacaine using a 25-gauge pencil-point needle. The patients received 0.5, 1.0, and 1.5 mg of bupivacaine at 1-week intervals to determine the optimal dose. Thereafter, they received two more weekly injections with the optimal dose. The safety and efficacy of the treatment were assessed over a 1-year period.
resultsNo serious adverse events were encountered. The optimal dose of bupivacaine (1.0 mg in 60% of patients) alleviated pain and disability (both, p < 0.0001) and provided anesthesia below L1 (L5-T6). Motor block was negligible, and balance impairment improved relative to baseline (p < 0.0001).
conclusionIntrathecal injection of low-dose bupivacaine offers a safe and effective treatment for chronic low back and lower extremity pain.
