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

backgroundCurrent trends in spine surgeries have shifted to minimally invasive procedures. Minimally invasive approaches are getting more popular for lumbar interbody fusion procedures.

objectivesThe objective of the study was to report technical modifications, learning curve, and short-term clinical results in minimally invasive transforaminal interbody fusion (MITLIF). MATERIALS AND

methodsAll MITLIF cases performed from 2018 July to March 2020 were included. First three authors were operating surgeons. Visual analog scores (VAS) scoring for pain, Macnab criteria, and Oswestry disability index (ODI) were used for outcome assessment. Operating time, radiation exposure, and complications were assessed separately in a group of 20 as per time sequence in series to assess the learning curve.

resultsA total of 61 patients were included. Various indications included spondylolisthesis, failed back surgery, calcified lumbar disc, and spondylodiscitis. Mean age was 47.08 ± 12.06. Intraoperative blood loss was 97.04 ± 25.58. Mean operating time and number of C-arm shots were 190.75 ± 37.11 and 159.3 ± 74.54, respectively, in initial 20 cases which however reduced in later operated cases. Significant improvement in VAS and ODI scores was observed at follow-up of 6.34 ± 4.67 months. Three cases needed surgical revision in the initial 20 cases, and there were no revision surgeries in later operated cases.

conclusionMITLIF could be done in failed back surgery cases, spondylodiscitis, and deformity corrections in addition to spondylolisthesis. It has advantages of less injury to soft tissues, maintaining the posterior tension band, decrease in blood loss and hospital stays, and early mobilization. However, it has longer learning curve and takes minimum 20 cases for the surgeon to acquire reasonable experience and confidence.
