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

Accumulation of GABA(A) receptors (GABA(A)Rs) at GABAergic synapses requires the cytoplasmic loop region and C-terminal transmembrane domain of the receptor gamma2 subunit. We here report a novel interaction of gamma2 with Calcium-Modulating cyclophilin Ligand (CAML), an integral membrane protein that regulates this mechanism. Interaction of GABA(A)Rs with CAML depends on both the cytoplasmic region and fourth transmembrane domain of the gamma2 subunit, CAML immunoprecipitates with GABA(A)Rs from transfected cells and brain lysates and colocalizes with gamma2 in ER vesicles in soma and dendrites of neurons. CAML shRNA treatment results in reduced expression of postsynaptic GABA(A)Rs, along with significant reductions in GABA-evoked whole cell currents and GABAergic synaptic function, while glutamatergic transmission is unaffected. Reduced surface expression of GABA(A)Rs in CAML mutant neurons is associated with selective deficits in recycling of endocytosed GABA(A)Rs to the cell surface. Our results indicate a specific role of CAML in functional expression and endocytic recycling of postsynaptic GABA(A)Rs.
