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 introduce and report early outcomes of an innovative surgical strategy to stabilize L5 PSOs with minimum 6 rods utilizing bilateral dual pelvic fixation consisting of both traditional iliac screws and osseointegrative S2AI screws.
methodsAdult patients at a single institution who underwent a L5 PSO reconstructed with a minimum of 6 rods using dual pelvic fixation were reviewed. Accompanying a description of the surgical technique is patient demographics, perioperative sagittal radiographic alignment parameters, and early surgical and clinical outcomes, including incidences of mechanical complications.
resultsSeven patients (4 females; average age 68 ± 8 years) met inclusion criteria. In addition to the L5 PSO, operative strategies were mixed [86% revisions, 86% lower thoracic UIV, 86% interbodies (ALIF, TLIF, DLIF) at either L3-4, L4-5, and/or L5-S1]. Average L5 PSO angle was 34.1
conclusionsBilateral dual pelvic fixation consisting of traditional iliac screws and osseointegrative S2AI screws to facilitate creation of "super" multi-rod constructs (minimum 6 rods) across L5 PSOs is a safe surgical strategy with promising early clinical results. Larger cohorts from multiple centers with longer follow-up will aid in determining its long-term efficacy.
