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.

Abstract
Long-term potentiation (LTP) and long-term depression (LTD) in the spinal dorsal horn reflect activity-dependent synaptic plasticity and central sensitization in chronic pain. Tetanic high-frequency stimulation is commonly used to induce LTP in the spinal cord. However, primary afferent nerves often display low-frequency, rhythmic bursting discharges in painful conditions. Here, we determined how theta-burst stimulation (TBS) of primary afferents impacts spinal cord synaptic plasticity and nociception in male and female mice. We found that TBS induced more LTP, whereas tetanic stimulation induced more LTD, in mouse spinal lamina II neurons. TBS triggered LTP, but not LTD, in 50% of excitatory neurons expressing vesicular glutamate transporter-2 (VGluT2). By contrast, TBS induced LTD and LTP in 12-16% of vesicular GABA transporter (VGAT)-expressing inhibitory neurons. Nerve injury significantly increased the prevalence of TBS-induced LTP in VGluT2-expressing, but not VGAT-expressing, lamina II neurons. Blocking NMDARs, inhibiting α2δ-1 with gabapentin, or α2δ-1 knockout abolished TBS-induced LTP in lamina II neurons. Also, disrupting the α2δ-1-NMDAR interaction with α2δ-1Tat peptide prevented TBS-induced LTP in VGluT2-expressing neurons. Furthermore, TBS of the sciatic nerve induced long-lasting allodynia and hyperalgesia in wild-type, but not α2δ-1 knockout, mice. TBS significantly increased the α2δ-1-NMDAR interaction and synaptic trafficking in the spinal cord. In addition, treatment with NMDAR antagonists, gabapentin, or α2δ-1Tat peptide reversed TBS-induced pain hypersensitivity. Therefore, TBS-induced primary afferent input causes a neuropathic pain-like phenotype and LTP predominantly in excitatory dorsal horn neurons via α2δ-1-dependent NMDAR activation. α2δ-1-bound NMDARs may be targeted for reducing chronic pain development at the onset of tissue/nerve injury.
