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

In the present study, 200-m swim time in highly trained male swimmers was measured on two consecutive days (Trial 1 and Trial 2) and under three conditions [(1) acute loading, AcL; (2) chronic loading, ChL; (3) Placebo, PLA]. No sodium bicarbonate (NaHCO(3)) was administered between Trial 1 and Trial 2 under each condition. Blood lactate concentration ([La(-)]), base excess of extracellular fluid (BE(ecf)), plasma bicarbonate concentration ([HCO(3) (-)]) and pH were determined before and after capsule administration as well as at 0, 3, 5, 15 and 30 min after each 200-m swim trial. Swim time was not different among AcL, ChL or PLA for Trial 1 or 2 and we observed no change in 200-m swim time from Trial 1 to 2 under any condition (F = 0.48, P = 0.80). [HCO(3) (-)], pH and BE(ecf) measured after capsule administration was higher during AcL and ChL when compared with PLA (P < 0.05). We did not observe any difference in blood [La(-)] between the three conditions at any stage post-exercise (P > 0.05). The results indicate that acute and chronic loading of NaHCO(3) does not improve 200-m swim time in highly trained male swimmers.
