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

purposeThe aim of the present study was to examine the natural history in patients with lumbar spinal stenosis. The incidence of surgery for this condition has increased considerably during the past decades in spite of a fairly favorable natural history in previous studies.

methods146 consecutive patients with clinical signs and image findings of lumbar spinal stenosis, who were not recommended surgical treatment, were followed; the reason as to why surgery was not recommended was a moderate symptom level. The follow-up rate was 89% after 3.3 years. Group values for comorbidities and diagnostic imaging were comparable to patients selected for surgery, with the exception of a lower frequency of degenerative spondylolisthesis among the non-operative patients. The mean age of those observed was 68 (21-91), and 58% were females.

resultsDuring the observation period spontaneous improvements were found for pain and health-related quality of life, but not for walking. Using the minimum clinically important difference for VAS, leg and back pain improved in 32 and 36% of patients, respectively, were unchanged in 55 and 54%, and worsened in 13 and 10%. Findings on diagnostic imaging did not influence patient outcome, except for stenoses with cross-sectional area <0.5 cm

conclusionsThe natural history of LSS with moderate symptom levels rarely shows symptom deterioration over a median of 3.3 years; in fact, a slight improvement of symptoms was seen at group levels. The treatment decision was revised for 7%, and for the rest an increase in pain was seen in 10-13%. The results support reluctance towards surgery, if the symptom levels are tolerable for the patients.
