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
Purpose: To evaluate the impact of bilateral ultrasound-guided erector spinae plane blocks (ESPBs) on pain and opioid-related outcomes in a surgical population with chronic pain. Methods: A retrospective, observational cohort study. Clinical data were extracted from the electronic medical records of patients who underwent lumbar fusion (February 2018 - July 2020). Eligible patients had a confirmed history/diagnosis of chronic pain starting >3 months before surgery and received either bilateral ESPBs or no ESPBs. Patients were matched on demographic variables (sex, age, race, BMI, ASA Classification, and preoperative opioid use) in a 1:1 ratio. The primary outcome was median opioid consumption (morphine equivalent dose, MED) 24 hours post-surgery (hydromorphone iv-PCA and oral). Secondary outcomes included Numeric Rating Scale (NRS) pain scores, opioid consumption up to 48 hours post-surgery, and hospital length of stay (LOS). Group differences were analyzed using bivariable and multivariable regression. Results: Of 72 patients, 36 received ultrasound-guided ESPBs and 36 did not. Baseline demographics showed no significant differences. On bivariable analysis, ESPBs were associated with significantly lower 24-hour opioid consumption (79 mg MED vs 116 mg MED, p=0.024) and shorter LOS (82 hours, 95% CI 51-106 vs 126 hours, 95% CI 101-167, p<0.001). No significant differences in NRS pain scores were found up to 48 hours post-surgery. Multivariable analysis confirmed significant reductions in 24-hour opioid consumption (-44, 95% CI -1.06 - -87.55, p=0.044), IV-PCA use (-22, 95% CI -1.59 - -56.77, p=0.038), and LOS (-38, 95% CI -10.074 - -66.22, p=0.008) in the ESPB group without differences in NRS pain scores. Conclusion: ESPBs were associated with statistically and clinically significant reductions in 24-hour opioid consumption and LOS, without differences in NRS pain scores after spinal fusion in a chronic pain surgical cohort. Given these effects, patients with chronic pain may disproportionately benefit from ESPBs for spine surgery.
