Effects of Peripheral Nerve Block on Perioperative Recovery following Major Thoracic and Abdominal Surgery: A Retrospective Cohort Study With Propensity-score Matching.
Article in Annals of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo test the hypothesis that peripheral nerve block (PNB) use might be associated with improved perioperative outcomes after major surgery.
backgroundPNB has been used to improve postoperative analgesia.
methodsThis was a retrospective cohort study with propensity score matching. We included patients aged ≥65 years who underwent major (≥2 hours) non-cardiac thoracic and abdominal surgery under general anesthesia. Data were analyzed according to whether patients received PNB or not during anesthesia. Our primary outcome was the length of hospital stay; secondary outcomes included occurrence of major complications in hospital after surgery.
resultsA total of 1915 patients were included in the full cohort, of whom 1316 received PNB and 599 did not; 1174 patients remained in the cohort after matching, with 587 in each group. Length of hospital stay after surgery was shorter in patients who received PNB than in those who did not [7 days (5-9) with PNB vs 7 days (5-11) without PNB: hazard ratio: 1.15, 95% CI: 1.02-1.29, P = 0.012]. When compared with patients who did not receive PNB, those who received PNB developed fewer major complications during hospital stay (relative risk: 0.41, 95% CI: 0.30-0.58, P < 0.001). Patients with PNB required less supplemental analgesia within 72 h (relative risk: 0.70, 95% CI: 0.59-0.84, P < 0.001).
conclusionsThe use of PNB was associated with shortened length of hospital stay and reduced major complications in older patients after major non-cardiac thoracic and abdominal surgery, possibly due to improved analgesia.
