Predictability of the preoperative lateral fulcrum radiograph of success in one-level vertebroplasty to treat painful osteoporotic vertebral fracture.

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
backgroundRestoration of height or angle has been reported following vertebroplasty (VP). The purpose of the study was to investigate the predictive value of the preoperative lateral fulcrum radiograph (LFR) of success in one-level VP for painful osteoporotic vertebral fracture.
methodsFrom January 2017 to January 2018, 71 patients (mean age, 76 years) receiving VP were retrospectively analyzed. Painful vertebra was defined as pseudarthrosis or edematous change in magnetic resonance imaging (MRI) scan. Fulcrum flexibility (FF) and fulcrum restoration index (FRI) of the vertebral wedge angle (VWA), regional kyphotic angle (RKA), and anterior vertebral body height (AVBH) were investigated. Back pain was evaluated using a visual analogue scale.
resultsThe 30 males and 41 females were followed for an average of 21 months. The sensitivity of LFR and MRI to detect pseudarthrosis was 92% and 97%, respectively. Preoperative FF of VWA, RKA, and AVBH was 52.4%, 58.3%, and 60%, respectively, indicating similar potential restoration ability. Postoperative average FRI for VWA, RKA, and AVBH was 1.29 ± 2.98, 0.46 ± 1.16, and 1.04 ± 1.68, respectively. Final average FRI was 0.94 ± 2.96, -0.03 ± 2.25, and 0.6 ± 2.04, respectively. VWA and AVBH had better immediate restoration, and VWA had better final maintenance. All parameters progressive lost significant levels of restoration to similar degrees but without increase in back pain.
conclusionLFR can help with evaluation for pseudarthrosis and the restoration effect of VP. VP had better immediate restoration of VWA and AVBH and better final VWA maintenance.
