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

purposeTo investigate the influence of facet tropism (FT) on spinal parameters and clinical symptoms of degenerative lumbar spondylolisthesis (DLS) after posterior lumbar intervertebral fusion (PLIF).

methodsA total of 108 patients with DLS who received PLIF surgery from June 2016 to June 2020 were retrospectively analyzed and divided into non-facet tropism (NFT) group and FT group according to bilateral facet joint angle (FJA) difference of more than 10°. Pre-postoperative clinical data compared between groups. Correlation analysis was performed between imaging parameter changes and symptom score changes. Groups were divided by preoperative FT segments to compare imaging parameters and symptom score changes with the NFT group.

resultsOverall, 54 patients were included in NFT group and 54 patients were included in FT group. The FT group had a lower lumbar range of motion (ROM) than the NFT group, with similar preoperative clinical data. Both groups showed improved imaging parameters and symptom scores after PLIF compared to preoperative levels. The ROM in the FT group was lower than those in the NFT group (P < 0.01). Both groups showed similar symptom improvements, but the FT group had significantly higher VAS and ODI scores at follow-up than the NFT group (P < 0.05). Improvements in VAS and ODI were significantly correlated with changes in imaging parameters and ROM in both groups.

conclusionPLIF improves DLS symptoms and lumbar curvature but restricts postoperative ROM. FT compromises correction efficacy, necessitating preoperative FT evaluation for optimal surgical planning.
