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

backgroundKlotho is a circulating anti-ageing hormone that predicts progression of cardiovascular and renal disease. The role of Klotho in diabetic retinopathy is unknown.

methodsWe performed a single-centre observational study of 81 people (males 62%) with type 2 diabetes followed for a median of 44 months. Circulating levels of Klotho and other markers, were measured from stored samples. The primary outcome was progression of retinopathy defined as new onset retinopathy or step change in retinopathy grading.

resultsDuring follow-up, 46 (57%) people reached the primary outcome. People with progression of retinopathy had lower levels of serum Klotho as compared to those without (median (interquartile range) 226.9 (171.1-394.0) vs 484.5 (221.8-709.9) pg/ml,

conclusionIn people with type 2 diabetes, lower circulating levels of the vascular protective hormone Klotho are associated with increased risk of progression of diabetic retinopathy. Klotho may be a novel biomarker and potential treatment target for diabetic eye disease.
