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

The aim of study was to assess the correlation between the changes in serum CK activity after a resistance exercise and renal function measured by glomerular filtration rate (eGFR). Twenty-nine trained women (32 ± 10 years; 157 ± 4 cm; 58.8 ± 6.4 kg) performed a resistance exercise session with 17 exercises with 3 × 12 repetitions in a circuit training fashion. Subjects provided blood samples prior to exercise session (PRE), and at 24, 48, and 72 h following exercise session for creatine kinase (CK) and creatinine. 24-Urine samples were collected before and 72 h after exercises. eGFR was obtained by the three most recommended methods (MDRD; MCQE; Cockcroft-Gault). After the exercise session, serum CK activity increase up 1.68 times (P < 0.01). Serum creatinine increased 25.5% (P = 0.0000) while urinary creatinine decreased on average 6.4% (P = 0.0422). eGFR decreased in all formulas: MDRD by 21.5%, MCQE by 14.2%, and C-G by 17% (all with P < 0.01). Ccr also decreased (-22.9%, P < 0.01). The index of correlation was significant for MDRD (r = -0.924; P < 0.01), C-G (r = -0.884; P < 0.01), and MQCE (r = -0.644; P < 0.05). In conclusion, we observed a significant negative correlation between CK activity and the eGFR indices of renal function.
