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
Introduction: Postoperative acute pain is a common challenge after breast cancer surgery. This randomized controlled trial compared the analgesic effects of ultrasound-guided erector spinae plane block (ESPB) and modified intercostal nerve block (MINB) in patients undergoing unilateral modified radical mastectomy. Methods: Seventy patients were randomly allocated to ESPB or MINB group. The primary outcomes were the 6-hour postoperative resting and movement-evoked Visual Analogue Scale (VAS) scores. Secondary outcomes included resting and movement-evoked VAS scores at 0, 3, 12, and 24 hours, intraoperative opioid consumption, rescue analgesic use within 72 hours, Quality of Recovery-15 (QoR-15) score at 24 hours, and hospital stay. Results: At 6 hours postoperatively, both resting VAS (median 2 [0-2] vs 2 [2-3], P=0.005) and movement-evoked VAS (median 3 [2-4] vs 4 [3-4], P=0.015) were lower in the MINB group. Resting VAS scores at 0 and 3 hours were comparable between groups. Movement-evoked VAS scores were lower in the MINB group at all post-surgery time points (P<0.05 for all). Intraoperative remifentanil consumption was lower in the MINB group (P<0.001). Fewer patients required rescue analgesics in the MINB group (P=0.038). No significant difference was observed in QoR-15 scores between groups (P=0.055). Conclusion: Ultrasound-guided MINB was associated with lower 6-hour resting and movement-evoked pain scores and reduced intraoperative opioid consumption compared with ESPB, without compromising recovery quality in patients undergoing unilateral modified radical mastectomy.
