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

Plasma membrane Cl(-)/HCO(3)(-) anion-exchange (AE) proteins contribute to regulation of intracellular pH (pH(i)). We characterized the transport activity and regulation by pH(i) of full-length AE3 and the cardiac isoform, AE3c, both of which are expressed in the heart. AE3c is an N-terminal variant of AE3. We also characterized AE1, AE2 and a deletion construct (AE3tr) coding for the common region of AE3 and AE3c. AE proteins were expressed by transient transfection of HEK-293 cells, and transport activity was monitored by following changes of intracellular pH or intracellular chloride concentration associated with anion exchange. Transport activities, measured as proton flux (mM H(+).min(-1)), were as follows: AE1, 24; AE2, 32; full-length AE3, 9; AE3c, 4 and AE3tr, 4. The wide range of transport activities is not explained by variation of cell surface processing since approx. 30% of each isoform was expressed on the cell surface. pH(i) was clamped at a range of values from 6.0-9.0 to examine regulation of AE proteins by pH(i). Whereas AE2 was steeply inhibited by acid pH(i), AE1, AE3 and AE3c were essentially insensitive to changes of pH(i). We conclude that AE3 and AE3c can contribute to pH(i) recovery after cellular-acid loading.
