Antiepileptic drug-induced severe granulomatous interstitial nephritis.
Article in BMJ case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Granulomatous interstitial nephritis (GIN) is a type of tubulointerstitial nephritis characterised by tubulointerstitial infiltration of mononuclear cells and eosinophils. It accounts for about 6% of all tubulointerstitial nephritis and is detected in ∼0.5%-0.9% of all renal biopsies. GIN has been linked to several antibiotics, non steroidal anti-inflammatory drugs (NSAIDs), and granulomatous disorders like tuberculosis and sarcoidosis but is rarely reported with anti-epileptic medications like phenytoin and levetiracetam. We present a case report of a man in his early 20's with previously normal renal function who developed GIN following levetiracetam and phenytoin consumption for 7 years. After withdrawal of the causative drug and starting steroid therapy, his kidney function gradually improved. In cases of GIN, medication history is important in the evaluation of aetiology.
