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
purposeTo determine the diagnostic performance of the Compression Overload Test (COLT) compared with the Straight Leg Raise Test (SLRT) in detecting lumbar intervertebral disc herniation (IVDH), using MRI as the reference standard. A secondary objective was to evaluate the correlation between each test and MRI results.
methodFifty-three 53 participants (mean age: 37.26 ± 12.16) with MRI-confirmed acute lumbar IVDH were included in the study. COLT and SLRT tests were conducted by the principal investigator, blinded to participant history, clinical findings, and MRI, while the co-investigator collected demographic and clinical data. Diagnostic performance was evaluated by sensitivity, specificity, and receiver operating characteristic (ROC) curve measures.
resultsCOLT demonstrated a higher diagnostic yield than SLRT, with a sensitivity of 92% and an overall diagnostic accuracy of 90.57%. It demonstrated moderate agreement with MRI findings (κ = 0.399) and a positive correlation (Φ = 0.428), with an area under the curve (AUC) of 0.793. In contrast, SLRT had no agreement (κ = -0.008) and no correlation (Φ = -0.0274) with MRI and a poor AUC (0.473). MRI predominantly identified L4-L5 herniations (47.5%) and disc bulges (54.5%). Vertebral endplate abnormalities, including Schmorl's nodes and Modic changes, were observed in 20 participants.
conclusionCOLT showed higher diagnostic utility than SLRT and correlated well with MRI results.
