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

purposeCompare the efficacy of full-endoscopic lumbar decompression surgery (FELDS) and open decompression and fusion surgery (ODFS) for lumbar spinal stenosis (LSS). PATIENTS AND

methodsA retrospective analysis of 358 LSS patients treated by FELDS ("FELD" group) or ODFS ("open" group) was undertaken. There were 177 patients in the FELDS group with a mean age of 65.47±9.26 years and 181 patients in the open group with a mean age of 64.18±10.24 years. Duration of follow-up was 38.63±11.88 months in the FELDS group and 38.56±12.29 months in the open group. Visual analog scale (VAS) score, Oswestry Disability Index (ODI), and Modified MacNab criteria were used to access clinical outcomes. Surgical outcomes (duration of surgical procedure, blood loss, complications, duration of postoperative hospital stay (DOPHS), prevalence of revision procedures) were evaluated. Magnetic resonance imaging was used to evaluate the change in the Pfirrmann grade at adjacent segments.

resultsVAS score (leg and back) and ODI improved significantly in both groups (P<0.001). Success rate reached 86.55% and 90.60% in the FELDS group and open group (P>0.05), respectively. Procedure duration (84.12 vs 112.08 min), blood loss (7.97 vs 279.67 mL), and DOPHS (2.68 vs 4.78 days) of the FELDS group were significantly better than those of the open group (P<0.05). Total prevalence of complications and procedure revisions was 14.69% and 10.73% in the FELD group, respectively, but did not show a significant difference with that in the open group (12.15% and 9.39%, respectively). The Pfirrmann grade increased in 13.04% of adjacent segments in the FELDS group, significantly better than that in the open group (32.67%) (P<0.05).

conclusionFELDS had the same efficacy as ODFS for LSS treatment. FELDS had the advantages of minimal invasiveness, less surgical trauma, rapid recovery, and lower risk of degeneration of adjacent segments compared with that of ODFS.
