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
introductionSymptomatic Adjacent segment disease presents in myriad ways with varying clinic-radiological presentation but the optimal management and the factors that predict need for revision surgery are unclear. METHODOLOGY: Consecutive patients (n = 132) who experienced significant back or leg pain after an asymptomatic period (minimum 1 year) following a lumbar fusion were evaluated with dynamic radiographs and MRI. ASD was classified anatomically as proximal (86.3%), distal (12.1%, or combined (1.5%) and, sub-classified pathologically into six sub-types: Type 1: Disc prolapse (17.4%), Type 2: Disc degeneration with intra-discal instability (15.1%), Type 3: Anterolisthesis and facet instability (6.8%), Type 4: Retrolisthesis (25%), Type 5: Stenosis (21.9%) and Type 6: Combined types (13.6%).
resultsThe mean duration between the index surgery and ASD was 5.9 ± 4.1 years. Surgery was required in 40.9% (54/132). Six factors were highly predictive of surgical treatment for ASD, viz., Diabetes mellitus (OR-4.3, p = 0.007), ASD- disc prolapse (OR 6.3, p = 0.018), ASD intra-discal instability (OR-16.8206, p = 0.003), ASD - anterolisthesis (OR - 8.2998, p = 0.043), Facet angle > 75° (OR 37.6, p = 0.02) and radiculopathy (OR 48.0, p = 0.002). Retrolisthesis was the most benign type as 84.8% patients were managed conservatively (p = 0.016). Among proximal ASD, retrolisthesis was the most common subtype (28.9%) while disc prolapse was the most common subtype in distal ASD 37.5% (p = 0.032).
conclusionThe study classifies the versatile clinic-radiological presentation of ASD, and identifies factors that predicted the development of the different sub-types of ASD. Knowledge about the six clinic-radiological factors that predict the need for surgical treatment in ASD is beneficial.
