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

STUDY

designRetrospective cohort study.

objectiveTo evaluate the relationship between early physical therapy (PT) for acute low back pain and subsequent use of lumbosacral injections, lumbar surgery, and frequent physician office visits for low back pain. SUMMARY OF BACKGROUND DATA: Wide practice variations exist in the treatment of acute low back pain. PT has been advocated as an effective treatment in this setting although disagreement exists regarding its purported benefits.

methodsA national 20% sample of the Centers for Medicare and Medicaid Services physician outpatient billing claims was analyzed. Patients were selected who received treatment for low back pain between 2003 and 2004 (n = 439,195). To exclude chronic low back conditions, patients were excluded if they had a prior visit for back pain, lumbosacral injection, or lumbar surgery within the previous year. Main outcome measures were rates of lumbar surgery, lumbosacral injections, and frequent physician office visits for low back pain during the following year.

resultsBased on logistic regression analysis, the adjusted odds ratio for undergoing surgery in the group of enrollees that received PT in the acute phase (<4 weeks) compared to those receiving PT in the chronic phase (>3 months) was 0.38 (95% confidence interval [CI], 0.360.41), adjusting for age, sex, diagnosis, treating physician specialty, and comorbidity. The adjusted odds ratio for receiving a lumbosacral injection in the group receiving PT in the acute phase was 0.46 (95% CI, 0.44-0.49), and the adjusted odds ratio for frequent physician office usage in the group receiving PT in the acute phase was 0.47 (95% CI, 0.44-0.50).

conclusionThere was a lower risk of subsequent medical service usage among patients who received PT early after an episode of acute low back pain relative to those who received PT at later times. Medical specialty variations exist regarding early use of PT, with potential underutilization among generalist specialties.
