1 · What the graph read from it

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.

2 · The registry

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

backgroundSurgically managing multilevel thoracic ossification of the posterior longitudinal ligament (mT-OPLL) remains technically challenging. Recently, a novel technique called thoracic controllable antedisplacement and fusion (TCAF) has been proposed as an encouraging procedure for this disorder. This study aimed to offer evidence regarding the safety and efficacy of TCAF surgery through a case series of mT-OPLL patients treated with this new technique.

methodsBetween August 2021 and May 2025, 3 consecutive cases of mT-OPLL treated by the TCAF surgery were retrospectively reviewed, and their surgery-related data and complications were collected. Additionally, the modified Japanese Orthopedic Association (mJOA) score, American Spinal Injury Association (ASIA) grade, and imaging parameters, including the type, involved levels, maximal thickness (mT) and maximal occupation ratio (mOR) of T-OPLL, spinal canal area (SCA) and diameter (SCD) at the narrowest level, and antedisplacement distance (AD) of the thoracic column, were evaluated before surgery and/or at the final follow-up.

resultsTCAF surgeries were successfully conducted in all patients (1 male and 2 females), and the average surgical level, operation time, blood loss, and hospitalization length were 8.33 ± 1.53, 530.00 ± 105.36 min, 600.00 ± 100.00 ml, and 20.00 ± 6.25 days, respectively. The mean mT and T-OPLL were 7.73 ± 1.05 mm and 7.67 ± 2.08, respectively. The average AD was 5.90 ± 0.20 mm. At the last visit, each patient achieved solid bony fusion with improved mOR, SCA and SCD. The average mJOA scores at the final visit were relatively greater than that before the operation (8.00 ± 1.00 vs. 3.67 ± 1.15), with a mean recovery rate of 59.72 ± 8.67%. In addition, the ASIA grades at the last visit improved in 2 patients but remained unchanged in 1 patient. No neurological deterioration or other serious complications occurred postoperatively, except for 1 case of cerebrospinal fluid leakage.

conclusionThe TCAF procedure, which allows canal decompression with no need for removal of T-OPLL, could be a promising surgical alternative for safely and effectively managing mT-OPLL.
