Electromagnetic Induction for Treatment of Unspecific Back Pain: A Prospective Randomized Sham-Controlled Clinical Trial.
Trial report in Journal of rehabilitation medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectiveTo evaluate the effects of high-energy pulsed electromagnetic fields on unspecific back pain.
methodsA prospective, randomized, sham-controlled clinical trial with repeated measurements was performed. The study included 5 visits (V0 to V4) with 3 interventions during V1, V2 and V3. Sixty-one patients aged between 18 and 80 years with unspecific back pain (acute inflammatory diseases and specific causes were reasons for exclusion) were included. The treatment group (n = 31) received 1-2 pulses/s, with an intensity of 50 mT, and an electric field strength of at least 20 V/m on 3 consecutive weekdays for 10 min each time. The control group (n = 30) received a comparable sham therapy. Pain intensity (visual analogue scale), local oxyhaemoglobin saturation, heart rate, blood pressure, and perfusion index were evaluated before (b) and after (a) V1 and V3 interventions. Change in visual analogue scale for V1 (ChangeV1a-b) and V3 (ChangeV3a-b), and ChangeData between V3a and V1b (ChangeV3a-V1b) for the remaining data were calculated (results were mean (standard deviation) (95% confidence interval; 95% CI)).
resultsConcerning the visual analogue scale: (i) compared with the control group, the treatment group had higher ChangeV1a-b (-1.25 (1.76) (95% CI -1.91 to -0.59) vs -2.69 (1.74) (95% CI -3.33 to -2.06), respectively), and comparable Change V3a-b (-0.86 (1.34) (95% CI -1.36 to -0.36) vs -1.37 (1.03) (95% CI -1.75 to 0.99), respectively); and (ii) there was a significant marked decrease in Change V3a-1b in the treatment group compared with the control group (-5.15 (1.56) (95% CI -5.72 to -4.57) vs -2.58 (1.68) (95% CI -3.21 to -1.96), p = 0.001, respectively). There was no significant ChangeV3a-V1b in local oxyhaemoglobin saturation, heart rate, blood pressure or perfusion index between the 2 groups and for the same group (before vs after).
conclusionNon-thermal, non-invasive electromagnetic induction therapy had a significant and rapid influence on unspecific back pain in the treatment group.
