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.
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
backgroundCKD has been recognized as risk factors for 25(OH) D deficiency, and Low levels of 25(OH) D have been suggested to be a trigger factor of decreased level of Hb. However, there is lack of information about the magnitude of 25(OH) D deficiency and Hb level in Nepalese CKD patients. Therefore, the aim of present study was to investigate the prevalence of abnormal 25(OH) D in non-dialyzed CKD patients, and further to examine its association with Hb level.
methodsIn this cross-sectional study, we examined 172 clinically stable patients with an eGFR at CKD stage2-5 not on dialysis. Serum 25(OH) D, Hb, levels were evaluated as a core variables and the other variables such as age, sex, co-morbidities (HTN, DM), eGFR, Hb, iPTH, serum phosphate, albumin, calcium, and phosphate level were evaluated as a covariates. Serum 25(OH) D, Hb levels and the factors associated with 25(OH) D level were evaluated.
resultsThe estimated prevalence of abnormal 25(OH) D metabolite (< 30 ng/mL) in this predialysis patients were (87.8%), with 32 and 55.8% deficiency and insufficiency 25(OH) D metabolite, respectively. On regression analysis, serum 25(OH) D was positively associated with male subjects (P = 0.02), serum albumin(P = 0.002), and eGFR (P = 0.042), while inversely associated with age (P = 0.006), iPTH(P = 0.025). Hb concentration was found to be positively correlated with 25(OH) D (P < 0.05) in both univariate as well as in multivariate analysis.
conclusionA high prevalence of abnormal 25(OH) D metabolite was observed in early CKD patients. Our study shows that lower level of 25(OH) D level are associated with lower level of Hb and higher level of iPTH, and could play a role in the development of anemia and hyperparathyroidism.
