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.

Abstract

backgroundOral nutritional supplements (ONS) are commonly prescribed to provide protein and energy to hemodialysis (HD) patients. There is a debate about the appropriate timing to administer ONS. We aimed to study the effect of different timings of ONS on variable outcomes in HD patients.

methodsThis research is a prospective, randomized, multicentric clinical trial (RCT) that included 120 patients on regular HD. Patients were allocated to receive ONS (25 gm protein powder/HD session) for 8 weeks either predialytic (1 h before the start of the session), intradialytic (2 h after the start of the session), or interdialytic (on non-dialysis days). Laboratory parameters, blood pressure (BP), dialysis adequacy, and nutritional parameters were assessed during the study.

resultsAt study end, BP at the end of HD dropped significantly in the intradialytic group compared to the other groups (p < 0.001). Serum albumin improved significantly in the predialytic (p < 0.001) and intradialytic (p = 0.039) groups. The mean subjective global assessment score increased significantly in the interdialytic group (p = 0.040). The Kt/V and urea reduction ratio decreased significantly only in the intradialytic group (p value < 0.001 and 0.001). Serum sodium, potassium, phosphorus, cholesterol, triglycerides, and adverse events did not significantly differ between the different groups.

conclusionsPredialytic ONS supplementation is a favorable option due to improved serum albumin with minimal effects on hemodynamics and dialysis adequacy compared to intradialytic and interdialytic supplementation.
