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

aimsSmall fiber neuropathy (SFN) is a peripheral neuropathy causing neuropathic pain, reduced quality of life (QoL), and high societal costs. Previous studies assessed these societal costs before a definitive diagnosis was established, leaving it unclear whether diagnostic confirmation affects costs, pain intensity, or QoL. This study assessed changes in these outcomes before and after diagnosis.

methodsPatients referred to the tertiary SFN expertise center in the Netherlands completed questionnaires before diagnosis (at placement on the waiting list, approximately 7 months before consultation) and at 3 and/or 6 months after confirmation. Healthcare utilization, patient and family costs, and productivity losses were assessed using the iMTA Medical Consumption and Productivity Cost Questionnaires. QoL was measured with the EQ-5D-5L and pain intensity with a numeric rating scale. Missing data were handled using multiple imputation, and changes over time were analyzed using within-subject comparisons and generalized linear mixed models.

resultsEighty-four patients completed both pre- and postdiagnosis questionnaires. After follow-up, total healthcare costs, patient and family costs, productivity losses, pain intensity, and QoL remained unchanged. However, diagnostic confirmation of SFN was associated with fewer medical specialist visits, lower related costs, and improved health perception.

interpretationThese findings suggest that diagnostic clarification alone is insufficient to reduce the overall burden of SFN, highlighting the need for more effective symptom management and supportive care strategies.
