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
backgroundTo date, the most commonly used endothermal ablation method is endovenous laser ablation (EVLA). The objective of this work is to assess the initial and short-term outcomes of a 1940 nm diode laser compared with 1470 nm diode laser utilization for the treatment of lower limb varicose veins.
methodsThis is a randomized controlled prospective study that included patients with varicose veins. The allocated patients were randomized according to the technique used: group I, which was treated using EVLA with a 1940 nm diode laser, and group II, which was treated using EVLA with a 1470 nm diode laser.
resultsThis study initially included 216 patients. After the exclusion of patients lost during follow-up, group I consisted of 105 patients, and group II consisted of 101 patients. There were high rates of anatomical success in the two groups with obliteration of the treated vessels at the 1-month follow-up (100% and 99%, respectively) and the 6-month follow-up (100% and 99%, respectively). A very low rate of adverse events was encountered (1%). Group II showed obviously longer median days to return for usual activities (11.5 compared with 7 days). They showed significantly higher pain scores, which was evident at the 7-day and 1-month follow-ups (P < .001).
conclusionsBoth lasers provided excellent outcomes in terms of anatomical success and low rates of adverse events. The 1940 nm diode laser was associated with lower median days to return for usual activities and significantly lower pain scores. Evidently, lower power and linear endovenous energy density were required for this laser.
