Microcirculatory function deteriorates with advancing stages of chronic kidney disease independently of arterial stiffness and atherosclerosis.

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
Cardiovascular disease is the main cause of mortality in chronic kidney disease (CKD). Endothelial dysfunction and capillary rarefaction are established cardiovascular risk factors. Nailfold video capillaroscopy provides a thorough assessment of capillary density and functional reserve. This study aimed to examine possible differences in structural and functional capillary density in CKD stages 2-4 with nailfold video capillaroscopy. Ninety-six CKD patients, divided into four equally sized groups according to CKD stage (2, 3a, 3b, 4), underwent nailfold video capillaroscopy, during which capillary density was measured at baseline, after 4-min arterial occlusion and after 2-min venous occlusion. Arterial stiffness and wave parameters were measured with applanation tonometry and common carotid intima-media thickness (ccIMT) with ultrasound. Baseline capillary density showed a progressive reduction with advancing CKD stages (stage 2: 32.6 ± 2.8, stage 3a: 31.2 ± 3.8, stage 3b: 32.5 ± 3.3, stage 4: 28.5 ± 3.1, p = 0.011). Similar reductions were observed during postocclusive hyperemia (39.4 ± 3.0, 37.6 ± 4.2, 38.4 ± 3.8, and 33.8 ± 3.3, respectively; p = 0.021) and after venous congestion (41.1 ± 3.1, 39.0 ± 4.4, 39.9 ± 3.5, and 35.2 ± 3.4; p = 0.032). Office PWV and ccIMT showed nonsignificant increasing trends with advancing CKD. In multivariate analysis, eGFR showed a positive association (per ml/min increase; β: 0.053, 95% CI: 0.004-0.101), whereas diabetes (β: -1.706, 95% CI: -3.176 to -0.236) and parathyroid hormone (PTH) (per pg/ml increase; β: -0.022, 95% CI: -0.036 to -0.008) had negative associations with postocclusive capillary density. Both structural and functional capillary density progressively decrease with advancing CKD stages. Apart from reduced eGFR, diabetes and increased PTH levels are independently associated with this reduction. This capillary rarefaction may largely contribute to the increased cardiovascular risk of CKD patients.
