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
To assess the value of contrast-enhanced lumbar MRI in guiding the selection of surgical approaches for recurrent lumbar disc herniation (RLDH) treated with full-endoscopic surgery. Clinical data were retrospectively analyzed from 237 patients with RLDH who underwent preoperative contrast-enhanced lumbar MRI. Surgical approaches were selected based on the location and degree of nucleus pulposus extrusion observed on MRI. The disc levels involved were as follows: L2/3 (1 case), L3/4 (11 cases), L4/5 (111 cases), and L5/S1 (114 cases). Surgical duration, intraoperative blood loss, length of hospital stays, and surgical complications were recorded. Clinical outcomes were evaluated using the Oswestry Disability Index (ODI) and visual analog scale (VAS) scores for low back and leg pain. All patients successfully underwent full-endoscopic discectomy. At one month postoperatively and at the final follow-up, VAS and ODI scores showed significant improvement compared to preoperative values (final follow-up vs. preoperative: lower back pain VAS [0.34 ± 0.50 vs. 2.54 ± 1.82], leg pain VAS [0.06 ± 0.29 vs. 5.53 ± 1.65], and ODI [0.51 ± 0.98 vs. 66.08 ± 47.14]). According to the modified MacNab criteria, outcomes were rated as excellent in 195 cases, good in 35, fair in 5, and poor in 2, yielding an excellent-to-good rate of 97.0%. No serious intraoperative, postoperative, or follow-up complications were observed. Contrast-enhanced lumbar MRI provides clear visualization of intraspinal anatomical structures in patients with RLDH, facilitating accurate preoperative determination of decompression boundaries. By assessing the spatial relationship between the reherniated nucleus pulposus and the pedicle, and incorporating iliac crest height and surgical history, the optimal surgical approach can be selected. This enables safe and effective removal of herniated disc material, adequate nerve root decompression, and favorable clinical outcomes.
