Downregulation of Na
Article in Chinese medical journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
background: Calcium regulatory proteins-L-type Ca
methods: After 30-min balanced perfusion, isolated hearts from rats were subjected to 30-min ischemia followed by 60-min reperfusion. Totally 40 isolated hearts were randomly assigned to four groups (n = 10/group): time control group, I/RI group, SevoPoC group, and DRIPC group. The effect of SevoPoC (3% v/v) and DRIPC were observed. Myocardial infarct size (IS), cardiac troponin I level, and heart function were measured. The protein and messenger RNA levels of LTCCs, RyR2, and NCX1 were determined.
results: Both SevoPoC and DRIPC improved the recovery of myocardial function, and reduced cardiac troponin I release after I/RI. The decrease in IS was more significant in the SevoPoC group than that in the DRIPC group (16.50% ± 4.54% in the SevoPoC group [P = 0.0006], and 22.34% ± 4.02% in the DRIPC group [P = 0.0007] vs. 35.00% ± 5.24% in the I/RI group, respectively). SevoPoC, but not DRIPC significantly inhibited the activity of NCX1 (0.59 ± 0.09 in the I/RI group vs. 0.32 ± 0.16 in the SevoPoC group, P = 0.006; vs. 0.57 ± 0.14 in the DRIPC group, P = 0.072). No statistical significant differences were observed in the expression of LTCCs and RyR2 between SevoPoC and DRIPC. In addition, subsequent correlation analysis showed a significantly positive relationship between the cardiac troponin I level and the protein expression of NCX1 (r = 0.505, P = 0.023).
conclusion: SevoPoC may be more effective in the cardioprotection than DRIPC partly due to the deactivation of NCX1.
