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

Introduction: Epidural steroid injections (ESIs) are commonly used for lumbosacral radicular pain, but clinical outcomes remain variable. Objective: This study aimed to identify predictive factors and determine short-term patient-reported outcomes in an understudied Southeast Asian population. Methods: A retrospective study involving 198 patients with chronic lumbosacral radicular pain undergoing lumbar ESI was conducted. Treatment success was defined as a ≥30% reduction in the Brief Pain Inventory worst pain score at 4-week follow-up. At follow-up, 167 patients had complete data and were categorized as responders (n = 83) or nonresponders (n = 84). Multivariable binary logistic regression was performed using observed complete-case data to identify factors associated with treatment success. Results: The observed 4-week response rate was 49.7%. In multivariable analysis, previous spine surgery was associated with lower odds of treatment success (adjusted odds ratio [aOR] 0.30, 95% confidence interval [CI] 0.11-0.80, Conclusion: Clinical history and treatment context were more informative than MRI findings for estimating short-term lumbar ESI response. Prior spine surgery was associated with poorer response, whereas unilateral TFESI was associated with higher odds of short-term treatment success.
