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
Background: Postoperative pain is a significant concern following percutaneous nephrolithotomy (PCNL). While tubeless PCNL has reduced discomfort, effective and simple analgesic techniques are still needed. Materials and Methods: A double-blind, randomized controlled trial was conducted at two tertiary hospitals with 120 adult patients having solitary renal pelvic stones <3 cm. Patients were randomized into two groups: the intervention group received 20 mL of 0.25% bupivacaine infiltrated into the tract at surgery end, and the control group received no infiltration. Postoperative pain was assessed using the visual analog scale (VAS) at 6, 12, and 24 h. Both patients and outcome assessors were blinded. Data from 57 intervention and 56 control patients were analyzed. Results: Baseline demographic, anatomical, and perioperative characteristics were well-matched between the two groups (all Conclusion: Infiltration of the nephrostomy tract with 0.25% bupivacaine is a simple and effective method for significantly reducing postoperative pain at 6, 12, and 24 h after tubeless PCNL. This technique provides a sustained analgesic benefit and should be considered for routine implementation to enhance patient recovery.
