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: Loin pain is a frequently reported symptom in IgA nephropathy (IgAN), but its significance is unclear. No known data exists regarding its prevalence, characteristics, or its impact on daily life, resulting in little support being offered for its management. Methods: A UK-wide mixed-methods study was conducted in collaboration with the National Registry of Rare Kidney Diseases (RaDaR). This included an online survey analyzed using descriptive statistics and group mean comparisons with adjustments for multiple comparisons. In addition, separate semistructured interviews were analyzed with reflexive thematic analysis and applied to the framework of the survey findings. Results: A total of 358 patients with biopsy-proven IgAN completed the survey. Twety-one completed the semistructured interviews. Loin pain was highly prevalent among those surveyed ( Conclusion: Loin pain was highly prevalent among patients with IgAN surveyed in the UK. Pain experience was similar and appeared independent of CKD stage. The pain had negative impact on psychosocial wellbeing, and limited support was provided. A need for better understanding of the pain and suitable management strategies was expressed by patients with IgAN.
