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.
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
purposeMinimally invasive tubular microdiscectomy is an effective treatment for lumbar radiculopathy with similar outcomes compared to open approaches based on short and mid-term data. This study examines patient-reported outcomes (PROMs) after minimally invasive tubular microdiscectomy with > 10 years of follow-up.
methodsConsecutive patients who underwent tubular microdiscectomy for lumbar disc herniation from May 1, 2010, to July 31, 2013 by a single surgeon at our institution were retrospectively reviewed. We measured VAS leg, VAS back, Oswestry Disability Index (ODI), EQ-5D-3 L and EQ-VAS scores as well as achievement of minimal clinically important difference (MCID). Multivariate analysis was conducted to assess factors associated with outcome measures and reoperation.
results103 patients were included, with a mean age of 52.0 ± 14.9 years, and 52 (50.5%) were female. Patients were assessed at baseline, short-term (6 weeks), long-term (3.8 ± 1.2 years), and very long-term (11.6 ± 1.4 years) follow-up. All PROMs improved significantly after surgery and continued to improve with longer periods of follow-up (p < 0.01). The 10-year reoperation rate was 8.7%. Multivariate analysis showed Worker's Compensation Board status to be associated with worse outcomes at short-term follow-up and BMI > 30 to be associated with increased reoperation.
conclusionsWe found continued improvement in PROMs after tubular microdiscectomy with > 10 years follow-up. Tubular lumbar microdiscectomy is a procedure with minimal risk, low revision rate, and lasting clinical benefit after more than a decade.
