The effect of ambient temperature and humidity on interdialytic weight gains in end-stage renal disease patients on maintenance hemodialysis.
Article in International urology and nephrology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeInterdialytic weight gain (IDWG) is both a measure of dietary compliance and a well-established predictor of future adverse outcomes in dialysis patients. The impact of environmental conditions on IDWG in end-stage renal disease is little studied to date.
methodsWe retrospectively reviewed IDWG for 100 consenting chronic end-stage renal disease patients undergoing thrice weekly in-center hemodiafiltration under three different climatic conditions in a Central European city: Weekend_1 was humid (93 %) and warm (24 °C); Weekend_2 was dry (38 %) and hot (33 °C); and Weekend_3 was dry (30 %) and warm (24 °C).
resultsThe cohort's mean age was 60.9 ± 14.7 years, all were Eastern European, and 56 % were men. Residual urine output measured 100 [25-75 % quartiles: 0, 612] mL/day, single-pool Kt/V 1.4 ± 0.25, and albumin 40.1 ± 3.9 g/L. Mean IDWGs measured as follows: Weekend_1 ("humid-warm"): 2973 ± 1386 mL; Weekend_2 ("dry-hot"): 2685 ± 1368 mL and Weekend_3 ("dry-warm"): 2926 ± 1311 mL. Paired-samples testing for difference showed higher fluid gains on the humid-warm (239 mL; 95 % CI 21-458 mL; p = 0.032) and on the dry-warm weekends (222 mL; 95 % CI -8 to 453 mL, p = 0.059), when compared to the dry-hot weekend. Under the latter, dry-hot climatic condition, residual urine output lost its significance to impact IDWG during multiple regression analysis.
conclusionWhile excess temperature may impact IDWG to a small degree, air humidity does not; the least weight gains occurred on the dry-hot weekend. However, the effects of both were minimal under continental summer conditions and are unlikely to explain large excesses of individual session-to-session variations.
