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

backgroundApproximately 400,000 diagnostic lumbar punctures (LPs) are performed by neurologists yearly in the United States. There has been a transition from neurologists performing >40% of LPs 2 decades ago to now <15% of the time. High body mass index (BMI) is one of the key obstacles of LP for neurology residents, and the success rates drop to 58% when BMI is >35 kg/m

methodsA prospective intervention study was conducted from March 2017 to March 2018 at an academic medical center. Patients were divided into ultrasound-guided LP or conventional LP. The primary outcome was the success rate of LP. The secondary outcome was the parameters regarding LP performance, the patients' feedback after procedures, and the residents' feedback about the learning modules.

resultsEighty-two patients were enrolled with inclusion criteria of age >18 years, BMI ≥25 kg/m

conclusionsThis study suggests that using ultrasound to localize before LP could increase the LP success rate and improve other related LP outcomes in the overweight populations. Our study also provides evidence that brief, targeted teaching modules are feasible and effective for ultrasound-guided LP training. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with BMI ≥25 kg/m
