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

background and purposeObesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. PATIENTS AND

methodsWe retrieved pre- and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005-2018. 4,069 patients had normal weight, 7,044 were overweight, 3,377 had class I obesity, 577 class II obesity, and 94 class III obesity ("morbid obesity"). Patient-reported outcome included satisfaction after 1 year, leg pain (Numerical Rating Scale [NRS], rating 0-10), disability (Oswestry Disability Index [ODI], rating 0-100). Complications were also retrieved.

results1-year postoperatively, 69% of patient of normal weight, 67% who were overweight, and 62% with obesity (classes I-III aggregated) were satisfied (p < 0.001) and 62%, 60%, and 57% in obese groups I-III, respectively (p = 0.7). NRS leg pain improved in normal-weight patients by 3.5 (95% CI 3.4-3.6), overweight by 3.2 (CI 3.1-3.2), and obese by 2.6 (CI 2.5-2.7), and 2.8 (CI 2.7-2.9), 2.5 (CI 2.2-2.7), and 2.6 (CI 2.0-3.2) in obese classes I-III, respectively. ODI improved in normal weight by 19 (CI 19-20), overweight by 17 (CI 17-18), and obese by 14 (CI 13-15), and 16 (CI 15-17), 14 (CI 13-16), 14 (CI 11-18) in obese classes I-III, respectively. 8.1% of normal weight, 7.0% of overweight, and 8.1% of obese patients suffered complications (p = 0.04) and 8.1%, 7.0%, and 17% among obese classes I-III, respectively (p < 0.01).

conclusionMost obese patients are satisfied after laminectomy due to CLSS, even if satisfaction rate is inferior compared with normal-weight patients. The morbidly obese have more complications than patients with lower BMI.
