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

backgroundHaptoglobin (HP), a plasma glycoprotein, binds to free hemoglobin and prevents the loss of iron and kidney damage. The variations of HP gene affect its enzyme activity, resulting in varied antioxidant, angiogenic and anti-inflammatory properties. HP 2-2 genotype showed 3.84 fold increased risk for the development of CKD in Taiwan population. With this background, the present work focused to conduct a prospective case-control study in South Indian population to evaluate whether the HP variants are associated to nondialysis (ND) (CKD stages 1-4) and ESRD (CKD stage 5) conditions. METHODS AND

resultsTotally 392 CKD patients (nondialysis, ND; n = 170, end-stage renal disease, ESRD; n = 222) and 202 healthy individuals were enrolled. The blood samples collected from the patients were used to determine biochemical parameters and HP genotyping. Gene frequency and biochemical parameters were statistically analyzed for disease association. Results showed that HP 2-2 genotypes were significantly associated with ND and ESRD disease development compared to controls. Higher HP2-2 genotype frequency showed an increased hazard ratio for overall disease progression among ND patients (hazard ratio = 3.86; 95% CI 1.88 to 7.93; P = 0.0002). Survival analysis also showed that non-HP2-2 patients have a statistically significantly decreased risk for mortality compared to patients with the HP2-2 genotype (ESRD patients hazard ratio = 4.05; P = 0.04).

conclusionThe present study confirms that HP2-2 polymorphism is statistically associated with the risk of CKD incidence, progression, and mortality among South Indians. Concluding our results, the HP2-2 genotype could be an independent predictor of all-cause mortality and disease progression in patients with CKD.
