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

objectivesThis study aimed to investigate the relationship of serum hemoglobin (HB) level with disease activity and structural damage in Chinese patients with rheumatoid arthritis (RA).

methodsA total of 890 RA patients and 890 normal subjects were enrolled in the case-control study. A HB threshold of< 110 g/L (women) and < 120 g/L (men) was used to determine anemia. All the patients were divided into three groups: non-anemia group (HB ≥ 120 g/L (male) or 110 g/L (female)), mild anemia group ((90 g/L < HB < lower limit of normal), and medium to severe anemia group (HB ≤ 90 g/L). Serum HB level and anemia prevalence between RA patients and normal subjects were compared. Associations of HB level with disease activity, structural damage, and function of joint in different groups were also investigated.

resultsThe average of HB level in RA was (109.08 ± 17.96)g/l, which was lower than that in controls (136.75 ± 14.57)g/l (P < 0.001). Anemia was observed in 47% of the RA patients, while prevalence of anemia in control group was only 4.4%. In RA group, percentages of non-anemia, mild anemia, and medium to severe anemia were 47%, 38%, and 15%. Compared with non-anemia RA patients, RA patients with anemia had higher disease activity, severer structural damage and worse function of joint (P < 0.001). With the increase of anemia, the disease activity, structural damage, and dysfunction of joints increased significantly (P < 0.05-0.001). Linear regression analysis showed that HB level was negatively correlated with disease activity parameters, degree of joint destruction, and function (P < 0.05-0.001). Logistic regression indicated that serum HB level was protective factors for disease activity and structural damage in RA (P < 0.001).

conclusionHB level was significantly related to disease activity and structural damage in RA patients.Key Points• Inflammatory anemia was popular (about a half) in patients with RA.• HB level was related to disease activity and structural damage in RA patients.
