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: Population-based estimates of anaemia prevalence in patients with chronic kidney disease (CKD) vary, and data on the prevalence of severe anaemia of CKD are limited. This study examined the prevalence of anaemia and anaemia eligible for erythropoiesis-stimulating agent (ESA) treatment in patients with CKD in the USA. Methods: National Health and Nutrition Examination Survey (NHANES) data from 1999-2000 to 2017-18 were used to determine the prevalence of diagnosed anaemia (haemoglobin <12 g/dL in women; <13 g/dL in men) and anaemia eligible for ESA treatment (haemoglobin <10 g/dL) in survey participants aged ≥18 years with stage 3-5 non-dialysis-dependent CKD (estimated glomerular filtration rate <60 mL/min/1.73 m Results: Of 51 163 eligible NHANES participants, 2926 (5.7%) with stage 3-5 CKD were included. In all participants, the weighted prevalences of anaemia and haemoglobin <10 g/dL were 25.3% and 1.9%, respectively. Mean haemoglobin levels decreased numerically between 1999 and 2012 and remained stable thereafter. The prevalence of anaemia and haemoglobin <10 g/dL increased with advancing CKD stage. The odds of haemoglobin <10 g/dL were significantly higher in stage ≥3B versus 3A and in non-Hispanic Blacks versus other races. Conclusions: In our analysis, approximately 25% of individuals with stage 3-5 CKD in the USA had anaemia and approximately 2% had anaemia eligible for ESA treatment.
