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
Store-operated calcium (Ca(2+)) entry (SOCE) mediated by STIM/Orai proteins is a ubiquitous pathway that controls many important cell functions including proliferation and migration. STIM proteins are Ca(2+) sensors in the endoplasmic reticulum and Orai proteins are channels expressed at the plasma membrane. The fall in endoplasmic reticulum Ca(2+) causes translocation of STIM1 to subplasmalemmal puncta where they activate Orai1 channels that mediate the highly Ca(2+)-selective Ca(2+) release-activated Ca(2+) current (I(CRAC)). Whereas Orai1 has been clearly shown to encode SOCE channels in many cell types, the role of Orai2 and Orai3 in native SOCE pathways remains elusive. Here we analyzed SOCE in ten breast cell lines picked in an unbiased way. We used a combination of Ca(2+) imaging, pharmacology, patch clamp electrophysiology, and molecular knockdown to show that native SOCE and I(CRAC) in estrogen receptor-positive (ER(+)) breast cancer cell lines are mediated by STIM1/2 and Orai3 while estrogen receptor-negative (ER(-)) breast cancer cells use the canonical STIM1/Orai1 pathway. The ER(+) breast cancer cells represent the first example where the native SOCE pathway and I(CRAC) are mediated by Orai3. Future studies implicating Orai3 in ER(+) breast cancer progression might establish Orai3 as a selective target in therapy of ER(+) breast tumors.
