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

This study aimed to investigate the incidence of renal anemia, defined as hemoglobin < 11 g/dL, in elderly patients on maintenance hemodialysis (MHD) and to analyze the associated risk factors and protective factors using a multivariable logistic regression model. A follow-up period of 6 months was used. A retrospective study was conducted on 120 elderly patients who underwent MHD at our hospital from January to May 2025. Demographic characteristics, comorbidities, and laboratory parameters were collected. Patients were divided into a renal anemia group (n = 90) and a non-renal anemia group (n = 30) based on the occurrence of renal anemia during follow-up. Differences between the 2 groups were compared, and indicators with statistical significance in univariate analysis were included in the multivariate logistic regression model. The incidence of renal anemia in elderly MHD patients was 75.0%, which is higher than previously reported rates in similar populations (typically ranging from 60-120%). Compared with the nonoccurrence group, patients in the occurrence group had significantly lower serum calcium, phosphorus, and pre-albumin (pre-ALB) levels, while serum intact parathyroid hormone (iPTH) and C-reactive protein (CRP) levels were significantly higher (P < .05). Correlation analysis indicated that serum calcium, phosphorus, and pre-ALB were negatively correlated with renal anemia, while iPTH and CRP were positively correlated with renal anemia. Further multivariate regression analysis revealed that higher serum calcium, phosphorus, and pre-ALB levels were protective factors, whereas elevated iPTH and CRP levels were risk factors. In conclusion, low serum calcium, phosphorus, and pre-ALB levels are risk factors, while elevated iPTH and CRP levels act as protective factors for renal anemia in elderly patients on MHD. Clinical management should emphasize nutritional support, regulation of calcium and phosphorus metabolism, and control of inflammatory responses to reduce the incidence of anemia and improve patient outcomes.
